What we choose to eat has an enormous impact on planetary health. The IPCC’s recently-released report made clear that either we pull out ALL of the stops and drastically reduce greenhouse gas emissions everywhere we can NOW (especially methane), or we accept responsibility for causing a climate catastrophe and bequeathing to our kids and grandkids a severely degraded planet, far less suitable for human habitation. Dietary change is simple, fast, and effective. It doesn’t require political will, new technology, trillions of dollars of investment nor decades of implementation. And it can dramatically shifts the detrimental level and kinds of impacts on our environment.
