Kangaroos do not release as much flatulence as cows. Now, I know what you are thinking right now, “Uhhhh. So what?” Well, this is much more important than you think.
Cow farts contain a lot of methane, which is a gas that adds to global warming by thickening the ozone. And seeing how much they flatuses they release and how many cows are currently being raised, you can do the math. In fact, about 14 percent of greenhouse gas emissions are emitted from bovine behinds.
Kangaroos, on the other hand, have a specialized bacteria in its stomach that cuts methane content to next to nothing. Scientists believe that if the bacteria can be transferred to cows and sheep, the 14 percent of harmful emissions from bovines can be eliminated.
There are added bonuses for farmers who otherwise may not want to pay for the procedure. Adding the bacteria to cow stomachs will make the animal’s digestive process more efficient, and save millions of dollars in feed cost. Athol Klieve, a senior research scientist with the Queensland government, said, “Not only would they not produce the methane, they would actually get something like 10 to 15 per cent more energy out of the feed they are eating.”
Researchers are quoted as saying it could take up to three years just to isolate the kangaroo bacteria, before the process of transferring them to cows and sheep can even be contemplated. This is where bioengineers like me can do work that can help the environment.
