As global population surges toward 9.1 billion people by 2050, Western diets rich in meat and dairy products will become unsustainable, according to a U.N. Environment Program report re-leased in May.
The report was prepared by the International Panel of Sustainable Resource Management, drawing on dozens of smaller studies. It notes that agricultural production accounts for 70 percent of global freshwater use, 38 percent of land use and 19 percent of greenhouse gas emissions.
The panel concludes that, just as fossil fuels will be gradually replaced by renewable, pollution-free energy sources like wind and solar power, meat and dairy products in the world’s diet will need to be replaced by vegetables, fruits and grains. Both shifts are absolutely necessary to reduce the production of greenhouse gases and the consumption of natural resources, as well as to ensure planetary survival.
As Americans, we have a special obligation to lead the rest of the world in a healthful diet of vegetables, fruits, and grains—a diet designed to prevent global starvation, while protecting our natural environment and safeguarding personal health. Each of us can start with our next trip to our supermarket.
