The one thing that every individual can do blunt the impact of climate change is change to a plant based diet. Farm animals, particularly beef cattle, produce massive quantities of methane gas, which is 20 times more potent as a greenhouse gas than carbon dioxide. Not only, is eating less or no meat good for the Earth, it’s also is good for the health of those that make that choice. It’s also very good all the billions of commodified animals that would other wise be killed and eaten by humans.

Our collective minds are stuck on this idea that talking about food’s environmental impact risks taking something very intimate away from us. In fact it’s just the opposite. Reconsidering how we eat offers us hope, and empowers us with choice over what our future planet will look like. And we can ask our local leaders – from city mayors to school district boards to hospital management – to help, by widening our food options.
On Monday and Tuesday, the city of Chicago is hosting a summit for the Global Covenant of Mayors for Climate and Energy to discuss climate solutions cities can undertake. Strategies to address and lower food’s impact should be front and center.
Animal agriculture is choking the Earth, and the longer we turn a blind eye, the more we limit our ability to nourish ourselves, protect waterways and habitats, and pursue other uses of our precious natural resources. Raising livestock for meat, eggs and milk generates 14.5% of global greenhouse gas emissions, the second highest source of emissions and greater than all transportation combined. It also uses about 70% of agricultural land, and is one of the leading causes of deforestation, biodiversity loss, and water pollution.
On top of this, eating too much meat and dairy is making us sick, greatlyincreasing our risk of heart disease, type 2 diabetes, several major cancers (including breast, liver and prostate) and obesity. Diets optimal for human health vary, according to David Katz, of the Yale University Prevention Research Center, “but all of them are made up mostly of whole, wholesome plant foods”.
So what gives? Why can’t we see the forest for the bacon? The truth can be hard to swallow: that we simply need less meat and dairy and more plant-based options in our food system if we’re to reach our climate goals.
To create change at the scale needed, this will take more than individual choice – we need to get climate leaders on board about the impact of food. Cities and counties have used their buying power to transition fleets from diesel to electric, and we need to do the same with how we purchase food. We have done this in our own community, moving the lunch program of Muse School, in Calabasas, California, and the Avatar movie set to plant-based menus. Scaling up initiatives like these can make a big difference: if the US reduced meat consumption by 50%, it’s the equivalent of taking 26 million cars off the road. We think that’s damn hopeful.
Yes, food is inherently personal. It’s the cornerstone of holidays, it fuels high school athletes and long workdays, and it nourishes nursing mothers and growing children. And yes, Americans love meat and cheese. But more than that, we love our majestic national parks, family beach vacations and clean air and water for our children and grandchildren.
As individuals, we can make choices on how to better nourish our families, and as citizens, we can encourage local leaders to make choices that will allow us to enjoy our land and natural resources now and in the future.
