Senator Andrew Bartlett - Member of Australian Parliament - Queensland, Animal welfare advocate & vegetarian:Global
 warming is probably the most important issue facing all of us and for 
taking the long term view we're facing an extremely serious threat of 
major climate change.
And frankly 
if we allow the current growth in livestock production to continue to 
occur then all of the other things that we try and do in changing the 
way we generate our energy is going to be cancelled out. 
Dr.
 Jonathan Patz, Lead author of United Nations Intergovernmental Panel on
 Climate Change reports, Professor of Environment and Public Health:
This
 is a challenge that is quite urgent. I mean it's really quite urgent, 
according to climatologists. We need to act soon, as in now.
"Three stops" critical for reversing global warming
Supreme Master Ching Hai :You see, we all know already through scientific evidence,and UN report that the stock raising causes a lot of methane gas, yes? 
And
 also, nitrous oxide, which is 300 times approximately more deadly than 
CO2, yes? If we stop the worst cause of global warming, meaning stock 
raising, animal breeding, then we will be able to save the planet. 
We have to stop the killing of man or animals. We have to stop producing animal's products. 
And we have to stop using it, ok? Three stops: 
Stop killing, 
stop producing, 
stop using. 
And stop eating it of course; stop eating the meat. 
Then the methane gas and the nitrous oxide gas will stop! 
And then we cut already, a big chunk of pollution off our air, and WE
 CUT OFF THE GLOBAL WARMING PROCESS. AND I SAID ALREADY 80% OF IT, WILL 
BE CUT ALMOST IMMEDIATELY, AND WE CAN SEE THE RESULTS IN A FEW WEEKS. 
3 Stops to 
Global Warming:
1. Stop Killing
2. Stop Producing
3. Stop Using/Eating
