Just thought I'd ask.
I don't know who "Bill Nye the science guy" is - but I would guess either he is not a very good "science guy", or perhaps you are misquoting him. Whichever is the case, the statement "cows are responsible for 20 percent of global warming
" is just silly. I suspect that your science guy is probably trying to tell you that after electricity generation, agriculture is the biggest source of anthropogenic greenhouse gas emissions. This is perfectly true, and something that is often overlooked. However, it is not in any way correct to say "cows are responsible for 20 percent of global warming
Perhaps you heard that agriculture and land clearing is responsible for some 20% of greenhouse emissions from anthropogenic sources. That is probably about right. And of that, methane emissions from livestock form a not insignificant proportion.
Or perhaps you heard that methane makes up about 20% of all anthropogenic greenhouse emissions. That is also probably about right. And of that, methane emissions from livestock, again form a not insignificant proportion of methane emissions from human activities.
But essentially - yes, you are right. We should reduce the amount of meat we eat. Land clearing, use of fossil fuels in agriculture, manufacture and use of fertilisers and methane generated by ruminants all contribute significantly to anthropogenic greenhouse gas emissions.
And ideally yes - cows should be gotten rid of, and instead eat the local native or feral herbivores. We have roos and camels and buffalo here. Can't you lot eat moose or something? Or better still, perhaps your government could set a bag limit to allow you to catch and eat any Americans that stray over the border. That would be a sensible policy for a better tomorrow.
