The leading cause of carbon emissions in the world is animal agriculture and no one is talking about it. This is the real issue that is driving climate change. … As a vegan I save 1,100 gallons of water a day. … If we are talking about a sustainability message, you cannot leave out the animal message – absolutely impossible. … We are looking at a world that is facing ultimate destruction if we don’t make better, smarter choices, and that starts with you. Every dollar you spend goes to feed a corporation that is either responsible or not responsible. … There are three things I want to make movies about: environmental problems, animals and human rights. Those are the three things I look out for all the time.

[To help combat climate change] Give up meat for one day (per week) initially, and decrease it from there. In terms of immediacy of action and the feasibility of bringing about reductions in a short period of time, it clearly is the most attractive opportunity.

President Herbert Hoover promised “a chicken in every pot and a car in every garage.” With warnings about global warming reaching feverish levels, many are having second thoughts about all those cars. It seems they should instead be worrying about the chickens. … It turns out that raising animals for food is a primary cause of land degradation, air pollution, water shortage, water pollution, loss of biodiversity, and not least of all, global warming. …The researchers found that, when it’s all added up, the average American does more to reduce global warming emissions by going vegetarian than by switching to a Prius. … Now that we know a greener diet is even more effective than a greener car, we can make a difference at every single meal, simply by leaving the animals off of our plates. Who would have thought: what’s good for our health is also good for the health of the planet!

Going vegetarian may be the most effective way to fight global warming. Buddhist practitioners have practiced vegetarianism over the last 2000 years. We are vegetarian with the intention to nourish our compassion towards the animals. Now we also know that we eat vegetarian in order to protect the earth...

If you can’t go vegan for the animals, why not go vegan for yourself? By switching to a plant-based diet, you won’t just help save animals’ lives, you might just save the planet. The meat and dairy industries kill 70bn animals every year – and a new report has found that they are on track to become the world’s biggest contributors to climate change. … Eventually, a tipping point will come, and the planet will turn into a gigantic slaughterhouse. It won’t be just calves and piglets these industries are killing – it will be you, your children and the children they could have gone on to raise. … So each time you eat bacon, or drink milk, you have not only invested in the slaughter of pigs or the abuse of cows, you’ve signed your own death warrant. For this is a problem that is predicted to escalate in the coming decades and emissions for agriculture are projected to increase 80% by 2050. In the 1980s, people started saying ‘meat is murder’, but it could become even worse than that – meat could mean Armageddon.

If anyone wants to save the planet, all they have to do is just stop eating meat. That's the single most important thing you could do. It's staggering when you think about it. Vegetarianism takes care of so many things in one shot: ecology, famine, cruelty.

There are however some things individuals can do to contribute to climate change reduction, adaptation and mitigation drive. For instance every individual needs to: educate himself/herself and others more about the climate change risks and the realities of adaptation. There is need for consciousness on the part of individuals to build capacity in adapting to climate change effects irrespective of his/her field in the economy in order to adapt to climate change. Activities that lead to pollution of the environment must be curtailed.

Human activities are the highest contributors to climate change.

We need to make decisions that make us less consumptive and reduce our reliance on nitrogen. It's like a carbon footprint. But you can reduce your nitrogen footprint. I do it by not eating much meat -- I still like a little every now and then -- not using corn oil, driving a car that I can put nonethanol gas in and get better gas mileage. Just things like that that can make a difference. So I'm challenging, not just you, but I challenge a lot of people, especially in the Midwest -- think about how you're treating your land and how you can make a difference. So my steps are very small steps. To change the type of agriculture in the US is going to be many big steps. And it's going to take political and social will for that to happen. But we can do it. I strongly believe we can translate the science, bridge it to policy and make a difference in our environment. We all want a clean environment.

Human activities are the main contributors to climate change

By eating meat we share the responsibility of climate change, the destruction of our forests, and the poisoning of our air and water. The simple act of becoming a vegetarian will make a difference in the health of our planet.

The single biggest impact a person can have on the Earth is driving a car, either driving a fuel-efficient car or just driving it less.

Identify an agrarian problem—greenhouse gas emissions, overuse of antibiotics and dangerous pesticides, genetically modified crops, salmonella, E. coli, waste disposal, excessive use of water—and trace it to its ultimate origin and you will likely find an animal. … Research shows that veganism, which obviates the inherent waste involved in growing the grains used to fatten animals for food in conventional systems, is seven times more energy efficient than eating meat and, if embraced globally, could reduce greenhouse gas emissions from conventional agriculture by 94 percent. … But with rare exception, those in the big, lumpy tent have thrown down a red carpet for “ethical butchers” while generally dismissing animal rights advocates as smug ascetics (which they can be) and crazed activists (ditto) who are driven more by sappy sentiment than rock-ribbed reason. It’s an easy move to make. But the problem with this dismissal—and the overall refusal to address the ethics of killing animals for food—is that it potentially anchors the Food Movement’s admirable goals in the shifting sands of an unresolved hypocrisy. Let’s call it the “omnivore’s contradiction.”

["Do you see a tie in between being a vegetarian and helping the environment?"] All of our cleaning products, lotions, shampoos, and toothpaste are organic and non-chemical, non-animal tested. You don’t have to be a vegetarian to be against animal testing, but it goes hand in hand. You know the rainforest that’s cut down or the land that’s cleared for cattle and factory farm animals, the destruction of the rain forest specifically for beef cattle is mind boggling to the both of us that they would destroy a very precious eco system just so cows have a place to eat grass. The people in South America don’t even really get to eat that beef but the land is being destroyed for it, and definitely the methane that’s produced from the cows and pigs. It’s definitely contributing to global warming. It’s hard for people to wrap their minds around the fact that their cheeseburger is making global warming worse. I think it’s an important message for people to get, but it’s hard for people to put the two together and make the connection.
