"So, what are scientists going to do about this? I mean, if cow farts cause global warming."
We cannot rely on scientists for everything. The only solution is for all americans to pitch in and do their part. We have to each hold our own gasses in internally and never release them. In an effort to diminish warming greenhouse gasses al gore has not farted since 1990. Yes, this causes the body to expand into a rotund shape, but the environment should be our first priority.
No, no...I saw a better solution. It was a patent( wish I could find it but I can't seem too) for a device to catch farts. A tube would be inserted up your anus and you would fart into it and the gas would be transmitted to a bottle worn under the clothes. I swear this was a real application for a patent, sometime in the 1890s. We could simply modify the bottle to have spark device that would periodically burn off the methane, or we could transfer the gas into the fuel tanks of our methane burning cars! Hows that, great idea huh? /humor off...
