The diversity of life on Earth, generally, is astonishing. But despite those large numbers, it's also important to recognize that every species, one way or another, is vulnerable to extinction. And in our time on Earth... our impact on the diversity of life has been profound.

Meat reared on land matures relatively quickly, and it takes only a few pounds of plants to produce a pound of meat.

Nearly all of the major kinds of life, divisions of life, phyla of animals, occur in the sea. Only about half of them can make it to land or freshwater.
