Indiana Jones Takes on Deforestaion and New Posts!


Hey all, seeing as things have gotten rather stagnant here, I have decided to change things up a little…again…I will be posting as I normally do on Sunday still (by the way, that post will be tomorrow).  But, I will also be posting on Monday, Wednesday and Friday.  Instead of the long posts, I will be posting a cool picture or video.  So, here we go…

As promised in the title…

And Now For Something Completely Different: Traffic


I decided to mix things up a bit around here.  Instead of my normal news post, I will be writing a story.  I hope you enjoy.

We started this whole operation almost five years ago.  We set up a front: a small exotic pet store which specialized in corals and tropical fish.  The store was fully operational.  Customers walked in and out without a clue of the ulterior motives we had.  I ordered fish that were nearly impossible to obtain in the United States.  Then, after what seemed to be an eternity of waiting, we launched our trap.

I sent a letter to one Anson Wong.  We had first heard his name when we interviewed animal traffickers.  Initially, we thought that he was simply a big player in the game.  Eventually, however, we learned that he wasn’t just a big player.  He was the player: the man who organized almost all foreign animal trafficking in South eastern Asia.

—–

Animal trafficking may not seem like a particularly big deal, but believe me, this is no simple import/export business.  International treaties like CITIES are in place to prevent the trafficking of endangered animals, but they don’t have any teeth.  First off, many countries do not abide by the rules because they did not sign it.  Also, it allows people to trade the animals if they were bred in captivity.  The problem here is that many people simply claim that their animal was “bred in captivity,” even though it was caught in the wild.  Once captured, the market is fairly specific for each animal.  Bears have their gall bladders removed for traditional medicines.  Tigers and big cats are killed for their pelts.  Monkeys are captured as pets.  Reptiles killed for skins and sometimes sold as pets.   The way these creatures are collected is also cruel.  Most traders will kill animals just for the parts with monetary value.  If an animal must be kept alive, they will commonly kill babies’ mothers and fathers and simply take the baby out of the wild.

I worked undercover in Wong’s organization for some time.  He, like most organized crime leaders, and make no mistake, it is highly organized, Wong bordered on megalomania.  I was supposed to be his biographer.  Wong showed me his captive breeding zoos.  They were little more than cages placed in his large estate.  There was no great difficulty in seeing through the mirage.  These animals were not bred in captivity.  There is a certain look in a wild animal’s eye when it is imprisoned.  It seems to ask, “Why?”  In one of our last meetings, Wong told me that he had to leave the country for a time to take care of some business.  I asked him where he was going.

“India,” he retorted.  “An associate tells me that I can have some tigers.”

“Tigers,” I thought to myself, “There are only about 4,000 left in the wild.  And I could guess what the tiger’s fate was going to be.  Tigers cost $6,000 annually to keep, but a bullet costs only a few cents.  The math is easy.

Before he left in his plane, he grabbed my shoulder.

“I have shown you much of my world.  Some people would like it dearly to see me behind bars for my….work.  Just remember, bad things happen to people who betray me.”

A chill went up my spine.  Wong was not one to make empty threats.  However, immediately on his departure, I went to the chief Wildlife Department official.  I told her that I had information regarding Anson Wong.  She laughed.  I asked for an explanation of her giggle.

“He is my friend,”  she simply replied.

I studied her face.  She did not blink.  Her smile displayed two rows of slightly angled white teeth.

“Nevermind,” I quickly said and turned and left.  Wong has his hand in every government agency I later learned.  His influence was far-reaching and solid as a rock.  If anything was going to be done, it would have to be in the United States.  Unfortunately, that meant for us to get charges to stick, we would need to catch him in the act.  But there was a hitch.  Wong never traveled with his animals.  It was always done through middle men.  We needed a good plan for this to work.

—–

My letter told Wong that I was a rare fish dealer and wanted to get some corals to add to my inventory.  This seemed like a low enough rung from which to start off.  We did not want to make a splash.  One toe at a time.  We also asked for a list of what he had to offer.  A month letter, we had a letter back.  It included a list of corals, including a few endangered ones.  We were on our way.  We ordered the endangered ones and asked to see what he had in way of fish and small reptiles.  He gladly complied with a similar list.  After another two years of correspondence, gaining Wong’s trust, we asked for a favor.

We had a “friend who was interested in Komodo Dragons.”  She “wanted” to meet Wong to set up a deal.  No good, he replied, he does not do business deals face to face, much less in North America.  But, she insisted.  Komodo dragons do not have a huge market as they are so conspicuous, so Wong did not want to lose this one.  After haggling on a location, we settled on Mexico, a country not known for its strict animal law enforcement.

It was a warm morning.  I waited outside of the airport tunnel entrance with a group of Mexican soldiers behind me.  Wong walked around the tunnel.  He had a Hawaiian shirt on, as though expecting to have some fun in the sun.  I greeted him with a smile and handcuffs.

“Hello old friend.”  I chided.

Wong’s face fell momentarily.  He knew the game was up.  But then, surprisingly, he smiled at me.

“Well done.  You really had me going there.  But no worries.  Just let my wife know that I will be gone for a while and that she should take over the store during my absence…”

For nearly two years Anson fought extradition to the U.S., but eventually he signed plea agreements, admitting to crimes carrying a maximum penalty of 250 years in prison and a $12.5-million fine. On June 7, 2001, U.S. District Judge Martin J. Jenkins sentenced him to 71 months in U.S. federal prison (with credit for 34 months served), fined him $60,000, and banned him from selling animals to anyone in the U.S. for three years after his prison release.  His main company, Sungai Rusa Wildlife, continued to ship despite the ban. Now that he’s free, Anson has launched a new wildlife venture, a zoo that promises to be his most audacious enterprise yet.

This story is, for the most part, sadly true.  To get the full story, check out http://ngm.nationalgeographic.com/2010/01/asian-wildlife/christy-text/1

Science and Soul: Nopenhagen


Science News in Brief

The discovery of a 4.4 million year old fossil skeleton that may have belonged to an early human ancestor was discovered in October.  Now, this discovery is hailed by the journal Science, as the greatest scientific breakthrough of the year.

Poll:

The Copenhagen Climate Summit has come to a close and here are some of the stipulations the loose agreement includes:

  1. recognition to limit temperature rises to less than 2 degrees Celsius.
  2. promises to deliver 30 billion dollars of aid for developing nations over the next three years, and 100 billion by 2020.
  3. includes a method for verifying industrialised nations’ reduction of emissions.

Turd Polishing: Making something crappy look better than it actually is.  That is how I define the above agreement.  It doesn’t look as if it will help much at all.  We are willing to admit there is a problem (the first step), but not willing to change.

Members of the European Space Agency have given final approval to plans to explore Mars.  The mission is to depart in 2018.

Mars Attacks: There have been 15 rovers sent to Mars.  There have been 6 manned missions to the moon.  One seems to interest scientists more than the other.

Cool Creature

The Northern blue-tongued skink, or Tiliqua scincoides intermedia, grows to 24 inches long, making it the largest of the blue tongued lizards.  These azure tongued beasties live in forests, woodlands, and grasslands of Northern Australia.  It is diurnal, and hunts for insects, snails, fruits, berries and wildflowers during the day.  At night, they are much less active and can be found resting in the hollows of logs.

Don't stick your tongue out at me.

Feature Story

Sorry I have once again neglected to post for a week, but exams take precedence.

Anyway, I have decided to post about the Copenhagen Climate Summit: formerly known as Hopenhagen, now seen as Nopenhagen.

I will now admit that I don’t really think that I should blog about this.  So much has already been said about Copenhagen that I will probably just wind up repeating what you have heard.  So, I just want to share with you what I consider an excellent assessment of the Summit.

By Amy Goodman

Denmark is the home of renowned children’s author Hans Christian Andersen. Copenhagen is dotted with historical spots where Andersen lived and wrote. “The Little Mermaid” was one of his most famous tales, published in 1837, along with “The Emperor’s New Clothes.”

As the United Nations’ climate summit, called “COP 15,” enters its final week, with more than 100 world leaders arriving amid growing protests, the notion that a binding agreement will come from this conference looks more and more like a fairy tale.

The reality is harsher. Negotiations have repeatedly broken down, with divisions between the global North, or industrialized countries, and the global South. Leading the North is the United States, the world’s greatest polluter, historically, and a leader in per capita carbon emissions. Among the Southern nations are several groupings, including the least-developed countries, or LDCs; African nations; and nations from AOSIS, the Alliance of Small Island States. These are places where millions live on the edge, directly impacted by climate change, dealing with the effects, from cyclones and droughts to erosion and floods. Tuvalu, near Fiji, and other island nations, for example, are concerned that rising sea levels will wipe their countries off the map.

New conceptions of the crisis are emerging at COP 15. People are speaking of climate justice, climate debt and climate refugees. Indian scientist and activist Vandana Shiva was among those who addressed a climate justice rally of 100,000 Saturday in Copenhagen. Afterward, I asked her to respond to U.S. climate negotiator Jonathan Pershing, who said the Obama administration is willing to pay its fair share, but added that donors “don’t have unlimited largesse to disburse.” Shiva responded, “I think it’s time for the U.S. to stop seeing itself as a donor and recognize itself as a polluter, a polluter who must pay. … This is not about charity. This is about justice.”

Shiva went on: “A climate refugee is someone who has been uprooted from their home, from their livelihoods, because of climate instability. It could be people who’ve had to leave their agriculture because of extended drought. It could be communities in the Himalayas who are having to leave their villages, either because flash floods are washing out their villages or because streams are disappearing.”

Both inside and outside the summit there is a diverse cross section of nongovernmental organizations, or NGOs, from indigenous-peoples delegations to environmental and youth groups. Their separate but connected efforts have been coalescing into a new movement, a movement for climate justice. Broad consensus exists among the NGOs and the global South that any agreement coming out of the U.N. process must be fair, ambitious and binding, or as they put it, “FAB.”

The Bella Center itself, where the summit is being held, is said by the U.N. to be at capacity. Thousands of people line up daily in the cold, vainly hoping to get in to the Bella of the Beast. Thousands more, from the NGOs, are having their access stripped, ostensibly to make room for visiting heads of state, their entourages and security.

Outside, Copenhagen is seeing an unprecedented police crackdown, with the largest and most expensive security operation in Denmark’s history. More than 1,200 people were detained over the weekend, and as this column goes to press, targeted arrests of protest organizers and police raids of public protest convergence spaces are being reported. Heavy-handed police tactics give another meaning to “COP 15.”

After South African Archbishop Desmond Tutu spoke at a candlelight vigil for children, I asked whether he thought President Barack Obama was following through on climate change. He responded: “We hope he will, yes. He has given the world a great deal of hope. I have said he’s now a Nobel laureate—become what you are.”

Last week, as a polar bear ice statue melted downtown, revealing the dinosaur skeleton hidden within, a small ice replica of Copenhagen’s famous Little Mermaid statue sat outside the Bella Center, melting. She is now gone. Obama is making his second attempt to win a prize in Copenhagen, after the Chicago Olympics embarrassment. Unless he uses the U.S. Environmental Protection Agency’s new determination that carbon dioxide is a public health hazard and nails down a fair, ambitious and binding agreement, we may see Andersen’s “The Emperor’s New Clothes” played out on the global stage.

The Cosmic Perspective

When will we ever learn?  I will be the first to admit that we cannot “prove” that global warming is occurring.  But, there are two problems with doing nothing.  First, we have very strong evidence to support that assessment.  The so-called “Climategate,” has been largely debunked as overblown sensationalism and nitpicking on the part of climate change deniers.  At this point, countless studies have been done and the most of the ones not backed by large corporations indicate that the climate is most definitely warming:

Second, we don’t have time to wait and see.  We need to act now if we wish to avert the worst that could occur.  I like to use the precautionary principle.  The precautionary principle states that if an action or policy has suspected risk of causing harm to the public or to the environment, in the absence of a scientific consensus that harm would not ensue, the burden of proof falls on those who would advocate taking the action.  If I see a mushroom in the forest, I will not eat it if I am not sure that it is safe.  Likewise, we should not continue on our track of aggressively using up fossil fuels to power our excess.

The entire Copenhagen summit was a debate between developed and undeveloped nations.  Developed nations decry developing nations for using dirty energy to advance their states, while developing nations yell back that developed nations use much more fossil fuels per capita and are already developed, so who are they to say others should not.  After much back and forth nothing much has been done. The developed accord is toothless, and not even binding at that!  It looks unlikely to contain temperature rises to within the 2 degree Celsius  climate change threshold that UN scientists say is needed to avert serious climate change.  Nor will it bring back the levels of CO2 in the atmosphere to 350 parts per billion, the level that scientists believe is the maximum to avert the aforementioned 2 degree change.  Unfortunately, since we are insulated by the bubble of wealth, we do not yet feel the effects of this oncoming storm.  But eventually, every bubble pops.  Will we be ready to deal with it?  Perhaps the one silver lining that I can draw from this meeting is that globally, we have recognized that there is a problem.  Now, we must act and make actual attempts to fix it.

Science & Soul: Cellular Automata


Science News in Brief

Turns out that the Iron Curtain helped isolate Eastern Europe from more than the Western world.  It also blocked the import of alien bird species.  Restrictions on the movement of people and trade in Soviet bloc countries prevented invasive birds being imported, a problem which has plagued much of Western Europe.

There is a difference: An introduced, alien, exotic, non-indigenous, or non-native species is one found outside its native range, having been brought their by humans through deliberate or accidental means.  Invasive species are introduced, but also have a detrimental effect on the environment.

The Intergovernmental Panel on Climate Change (IPCC) released a statement that the emails hacked from scientists’ computers did not contain information which indicated that human created greenhouse gases were not a factor in global warming.

Quirky Quote: “There is an anti-change group. There is an anti-reform group. There is an anti-science group, there is a flat Earth group, if I may say so, over the scientific evidence for climate change.” –Gordon Brown

Researchers have released a study showing that there are large variations in the amount of carbon being absorbed in the North Atlantic: as much as 10%.   They are still doing research to understand what causes these differences.  Currently, the ocean absorbs about half of carbon emissions from human activities.

Apocalypse Scenario: Here’s a nice positive feedback loop for ya: as the climate warms, the ability of liquids to absorb gases decreases (think pop cold vs pop warm), increasing global temperatures, decreasing the ability of the ocean to absorb carbon dioxide…crap.

Cool Creature: Superb Fairywren

Cute Superb Fairywren

The Superb Fairywren, Malurus cyaneus,  is a a small bird found across south-eastern Australia.  The male of the species has a bright blue head, back and tail, with a dark mask, and buff belly.  The female, however are a dull brown colour.  This example of sexual dimorphism is fairly common in the bird world.  The bird is known for its strange mating behavior.  The male wren will pluck yellow flower petals and display them to females.  Although it is socially monogamous, in that they will form fairly regular pairings, but one male will father many chicks with multiple females.  And, he will help raise most, if not all of them.  This causes a rather complex social dynamic.

Feature Story: Cellular Automata

So this is my first post where I talk about what I do as a bioengineer.  People often tell me, “So you mess with genes and stuff, right?”  First, nobody is “messing” with anything.  Second, not really.  I specifically enjoy working with complex ecological systems.  I work to better understand the causes and effects of environmental changes due to natural and human-caused events. Bioengineering allows me to have a holistic look at ecological systems.  Emergent behaviors result from nonlinear interactions between individuals in these ecological systems.  Eventually, I plan to do field research as well as computer modelling to help change the many problems our environment faces.   One of my tools as a bioengineer is cellullar automata.  Have no fear: this is not going to be a trip down molecular biology lane.  Not necessarily anyway.

Networks are built when individuals interact with their local neighborhood, their surroundings.  Thus, range and links are important in a network.  If a system is a complex system with multiple networks, nonlinear interactions among individuals can spontaneously create patterns from an initially random or uniform area. A grid model made up of many individuals represented by cells, or automata (us engineers like to make things complicated sounding), whose possible states are finite and distinct can be updated based on a function which refers to the state of each automata’s neighbors.

Perhaps a good way to explain this is to delve right into an example.  Image a 100 x 100 grid.  This represents a theater.  Each grid space represents a person in the theater.  We want to test the effects of fire on the movie goers.  Let’s say that if 4  people or more around an individual is scared, the middle person is scared.  Otherwise, the cell’s status is normal.  By using a computer program, we can quickly perform multiple iterations of these tests on each of the 10,000 individuals in the test to see if there is any emergent behavior.  Emergent behavior is such that results from nonlinear interactions between autonomous agents in a complex system. That is, it is neither completely random nor completely structured.

So how does this relate to the environment you ask.  Well, I recently completed a project to model ecological succession from bare soil.  Each individual tree species is predisposed to a certain environment.  In turn, each tree affects the environment.  For example, most climax trees are shade tolerant, that is, they grow well in light deficient conditions.  This allows them to grow where there are already a number of pioneer (fast-growing, light-loving) trees.  They in turn create more shade, helping climax trees compete against pioneer trees.  In developing my model, I decided to focus on three main variables which determine plant growth: the soil’s water content, the soil’s pH, and the amount of light in the area.  I also chose the most common trees in an Eastern deciduous forest as my possible states.  To account for the possible variables in the environment, I calculated the amount of trees surrounding a given cell.  The higher the number of trees, the higher the amount of shade, and the less sunlight will reach the trees. I also totaled the number of trees surrounding each cell to calculate water usage.  The more trees there were (as opposed to blank spaces), the less water there was for that area of land.  There are no units for the variables per se, but they can be interpreted as described above.  I then developed a function which would analyze the current state of a cell and compute what the future state of the cell will be.  So, if the current state in the cell is bare soil, then it will either continue to be bare soil or a tree will grow there.  The simulation began with a white field (all blank) as would a piece of land after a disaster leaving bare ground.  In the next time step, pioneer trees came on the scene.  Following this, a few climax trees appeared, and more pioneer trees grew, removing many more of the plots of bare ground.  In the subsequent time steps, more climax trees grew and ultimately dominated the field in the simulation.  By the tenth time step, there was some flux, but most of the trees were of the climax varieties.  There would always be some pioneer trees.  When a tree “died” and resulted in open ground, the first trees to fill the gap would often be pioneer trees, but these are quickly weeded out.  Thus, I used cellular automata to model a biological phenomenon involving emergent behavior.

Secondary Succession: A Cellular Automata Application

Cosmic Perspective

What am I, as a bioengineer, doing with this information?  In my example, I modeled secondary succession, an already understood process.  However, there are other applications.  I know individuals who have used this technique to model forest fires based on forest density.  I have seen the effects of the surroundings on a cell’s (living cell, that is) processes modeled to test new drugs.  The future is truly limitless, but we must understand that we must also ask ourselves whether or not our methods are being applied in such a way to help, rather than harm, the world.  Science is useless without ethics.

Science & Soul: I’m Back!


Sorry about the long wait, but work comes first.  Anyway, I am getting back in the swing of things for a little while.

Science News in Brief

The Large Haldron Collider has resumed operation and set a new world record for energy.  Its particle beams were accelerated at over one trillion volts.  This was just a precursor to the Collider’s primary scientific tests set for the year 2010.

Still No Black Hole: Just to give you a sense of the energy involved here: a lightning strike hits with about 1 billion volts.

A cross-disciplinary team of researchers from universities across America have released a study which indicates that climate change could increase the likelihood of civil war in sub-Saharan African countries by as much as 50% in the by 2050.  These wars would be fueled by decreased water supplies, fewer food sources, and increased poverty rates.

Talking World War III Blues: Already, 5.4 million people have died from civil war the civil war in the Democratic Republic of Congo, making it the deadliest conflict since World War II.

Scientists seem to have discovered the reason for the hammerhead shark’s strange head shape.  The shape allows sharks to see almost in 360 degrees in binocular vision.

Weird Animal Fact: The mantis shrimp has the best eyesight in the animal world.  It is the only animal to to have hyperspectral colour vision.  That is, it can see across the electromagnetic spectrum.  We can only see visible light.

Cool Creature

I already covered the kakapo, but I have been dying to post this video.

Feature Story: Remember Me

Are some animal species more important than others?  A recent study which examined 222 carnivore species around the world points to the fact that certain carnivores should be more protected than others due to their ecological importance and individuality.

Even though carnivores are probably the most studied animal group, their taxonomic connections are not well understood.  Thanks to genetic testing, scientists are now able to construct much more accurate taxonomic maps.

The study supports the theory that describes the split of carnivores into two main evolutionary groups: dog-like carnivores (Caniforms) and cat-like carnivores (Heliforms).  The same study also revealed some so-called Confused carnivores which do not fit neatly into the aforementioned classification.

Researchers performing the study also isolated a number of carnivores which are unique in the ecological services they perform and the way they evolved.  They suggest that these species, including monk seals, red pandas, and walruses, should be more protected than others because they are so unique.  Because they are evolutionarily distinct, they have genes and evolutionary history not found in any other species.  This makes it important with regards to biodiversity: by increasing genetic variability.

The Cosmic Perspective

All people value equality: the right to be treated with equal respect and dignity as any other human being.  Those who value the environment tend to extend that to the animal world.  We do not like to show preferential treatment to certain animals just because they are cute and cuddly.  So, this study which claims that certain animals are more important from an evolutionary perspective comes as a bit of a shock.  Why should a walrus be more important than a snow leopard?

I look at this from two points of view: that of a scientist and that of an environmentalist, because I consider myself to be both.  As a scientist, I definitely see the merit of protecting certain species.  Different animals perform different tasks in an ecosystem.  Certain animals’ roles are more critical to the functioning of the system as a whole than others.  It is a principle of network systems thinking that  nodes (animals) in a system (ecosystem) can be ranked based on the number of nodes which connect to them and the importance of those nodes.  So, the more important connections an animal has, the more important it is in an ecosystem.  However, even a few important links can prove to elevate a species to a higher status than one with many relatively commonplace connections.

That being said, all animals play an important role in biodiversity.  Biodiversity provides for the astounding variety of different organisms, genes, ecosystems in which they exist, and biological services these organisms provide for life to adapt to changing environmental conditions throughout history.  It would be foolish not to save as much as we can of the already dwindling amount of biological diversity we have on this planet.  We often do not know how important something is before it is gone altogether.

A Strange System: Food: What We Can Do


I’m all ranted out for now, so I shall bring this series to a close.  I have hinted at a number of things we, the average consumer, can do to improve the system.  So, to finish off the series, I am posting a list created by a professor of Environmental Studies, Dr. Richard Andrus, which I think is completely reasonable to attain.

For personal health-

  1. Eat more whole foods and avoid processed sugars & starch.
  2. Avoid factory farmed meat, dairy & eggs wherever possible.
  3. Eat modest amounts of grass-fed meat.

For the environment-

  1. Avoid factory farmed meat.  They cause massive pollution issues from concentration of nitrates and massive erosion from corn & soybean production for animal feed.
  2. Buy local. This cuts back of food miles and helps reduce CO2 emissions.
  3. Buy unprocessed food, as processing takes huge amounts of fossil fuels.
  4. Avoid any processed drinks that come in a non-reusable container. The only reusable containers available currently are glass beer bottles from Canada. Recyclable does NOT mean reusable. Most recycled containers end up in the landfill.
  5. Buy organic, as long as it’s unprocessed.
  6. Grow, cook and brew your own.

For everything!

1. Purchase as little food as possible that results in profits for corporations. There are two reasons. One is that by law they are bound to maximize profits for shareholders, which means they are bound to take advantage of human weaknesses that attract us to unhealthy foods. The second reason is that a prime way to increase profits is do whatever you can legally do to externalize the costs of your activities. This results in pollution from agricultural fields, abuse of farm workers. contamination from factory farms, abuse of farm animals,and  huge production of packaging solid waste.

A Strange System: Food: Hard Travelin’ Blues


You walk through the aisles of your local supermarket.  Apples in June.  Watermelons in February.  Oranges in December.  Weird star fruit in….well I don’t actually know if star fruit have a picking season.  So how do we have these fruits and vegetables when it is not time for them to be picked.

Most of our food doesn’t come from the good ol’ USA.  As I previously mentioned, we mainly grow corn.  Most of that is used for biofuels and livestock feed.  So where do we get all this stuff?  Well, where is it warm and rainy all year-round (and cheap to grow)?  Thing South.  We get a vast majority of our produce (when not in season) comes from Mexico, Brazil, Columbia, and Brazil.  If you have time, I suggest you actually go to your local supermarket and ask the manager from where the produce is coming.  99 times out of 100, you will get a blank stare.

As a nation, we have become so disconnected from the very sustenance we need for survival.  Most urbanites think farmer as being synonymous with country bumpkin, redneck, hillbilly, or quaint.  There is a social stigma to be a farmer.  But should those farmers disappear, well, the high and mighty urbanites are in for a world of hurt.  In fact, this may not be as strange as one would think.  Since 1979, 300,000 small farms have disappeared in the United States, and since 1946 the number of people who make their living by farming has been cut in half. Increasingly, large companies like Monsanto and Carghill take over and force farmers out of their land.

Farmers' Numbers Decrease

Farmers' Numbers Decrease

Back to the food.  So these crops are being grown in countries far away from all of us.  The workers who are spraying the pesticides we previously mentioned, working long hours in the hot sun are probably not being paid very well.  But that is not a problem: we get our watermelons cheap!  The crops are finally picked.  Now what?  The crops are put in an air-conditioned airplane and flown to packaging and distribution centers throughout the United States.  Then, they are shipped in air-conditioned trucks all over the country on our wonderful highway system.  This is hugely energy intensive.  It is estimated that the average American family’s meal has traveled almost 10,000 miles before it reaches the plate (in December, to be fair).   Scientists have clocked energy usage as being 10 calories of fossil fuels for 1 calorie of food.  Talk about inefficient.

The Cosmic Perspective

Perhaps for the purposes of this series the Cosmic Perspective should be retitled to What You Can Do.  Oh well, too late.

If ever there was a simple way to make a difference it is to: buy local and in season!  Simple!

Don’t buy those apples in June or watermelons in February.  Eat what is available in your zone when you plan to eat it.  That might mean doing without some things.  Unfortunately, most Americans are still in the mentality that they want it all and they want it now.  So visit your local farmer’s markets.  Not only will you help support the local economy (that is all the rage), but you will be eating better: better for you and for the environment.  Build a relationship with those great folks who grow your food.  Check out this link to find more links regarding local eating:

http://www.animalvegetablemiracle.com/LocatingLocal.html

I don’t mean that you have to drop oranges altogether.  I have eaten a star fruit.  Guilty as charged.  But all good things in moderation.  Once in a while is fine, every day is where the problem arises.

In her book, Animal, Vegetable, Miracle, Barbara Kingsolver notes,

“The main barrier standing between ourselves and a local-food culture is not price, but attitude. The most difficult requirements are patience and a pinch of restraint – virtues that are hardly the property of the wealthy. . . We’re raising our children on the definition of promiscuity if we feed them a casual, indiscriminate mingling of foods from every season plucked from the supermarket, ignoring how our sustenance is cheapened by wholesale desires. Waiting for the quality experience seems to be the constitutional article that has slipped from the American food custom…We have the illusion of consumer freedom, but we’ve sacrificed our community life for the pleasure of purchasing lots of cheap stuff. Making and moving all that stuff can be so destructive: child labor in foreign lands, acid rain in the Northeast, depleted farmland, communities where the big economic engine is crystal meth. We often have the form of liberty but not the substance.”
