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.

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:

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.
