I recently saw one report on this news while eating more meat, that means heat from human beings releasing would raise atmosphere temprature, is it true or not? But by the way like Elephant and Rhinos ,who are eating a quite amount of plants whereas other African animals need commonly, that also can release more heat energy to outside is a good things or not, I am wondering. So coming the question, what is the affect in case of the "Big Guy" extination, although I am not expecting a killer in all.
Cows release a lot of methane gas due to cow their digestive systems work, and we've bred a lot of cows for consumption - far more than would occur naturally A quick google tells me that about 13% of global emissions come from agriculture, and about 25% (about a quarter of a pi chart that didn't include numbers) of that comes from methane release of livestock. That's a total of roughly 3% of global emissions.
Regarding to the group of meat defeaters, it is not quite attractive news hearing about the conclusion from UN report that I have to say. The meat would be more reproduced by humans anthropic involvement, which is reasoned by our selfish stomache in engoging. If someone like eating beef or cutton in restaurant or house, more than two cows or sheep that could be prepared to be killed in market. That urgency is the root reason that more than four shepherd who will feed themselves upon esculent animanls themselves as an example. While after in all , geometric multiples of animals are able to die from our executioner, hahaha.
The key to issue of earth warming is how to reduce humans' activities in industry or factory as reported long time ago, although it is under discussion, I agree. But it should not be only existing factor that warmer atmosphere ,at meanwhile, it should be realized in deep thinking.
Just now I found online that "According to a 2006 report by the United Nations Food and Agriculture Organization (FAO), our diets and, specifically, the meat in them cause more greenhouse gases carbon dioxide (CO2), methane, nitrous oxide, and the like to spew into the atmosphere than either transportation or industry."
If I didn't have any sources, I would say it doesn't, but apparently it does... It's surprising to me, I would think all the CO2 and other chemicals released by farm animals are part of the ecosystem. They aren't being added, just moved around.
But apparently my intuition is wrong on this one. Maybe there is an indirect way that is causes these chemicals to be released (like machinery, or feeding chemicals that aren't part of the ecosystem).
(Regardless if whether it causes global warming, it will be easier to solve world hunger if more people go vegetarian or vegan, so it's definitely something to consider even if you don't care about animals).
