I suspect most of you already do many things to help preserve the viability of the planet we all call home. Perhaps you recycle glass, plastic and paper and compost organic waste; shop with reusable bags; rely heavily on public transportation or bicycles or, failing that, at least drive fuel-efficient cars.

But have you given serious thought to the planetary effects of what you eat and made changes that will protect not only terra firma and surrounding waters but also your health and the well-being of generations to come?

In January, The New York Times described a comprehensive new report from the EAT-Lancet Commission on Food, Planet and Health. It was compiled by 37 scientists and other experts from 16 countries, with the aim of establishing a global food economy that could combat chronic diseases in wealthy nations like ours and provide better nutrition for poor ones, all without destroying the planet. The scientists’ goal was to outline a healthy sustainable diet that could feed the nearly 10 billion people expected to inhabit the world by 2050.

For more than a century, most Americans have been eating far too high on the hog for the sake of their own health and the health of the planet. In 1900, two-thirds of our protein came not from animals but from plant foods. By 1985, that statistic was reversed, with more than two-thirds of our protein coming from animals, primarily beef cattle. They consume up to eight pounds of grain to produce one pound of meat and release tons of greenhouse gases in the process while their saturated fat and calories contribute heavily to our high rates of chronic diseases.
