Too many people, too much consumption, and growth

mania. At the age of 90, biologist Paul Ehrlich

may have lived long enough to see some of his

is not sustainable. To maintain, uh, our lifestyle,

yours and mine, basically for the entire planet,

you'd need five more Earths. Not clear where

they're gonna come from. Just in terms of the

resources that would be required. Resources

that would be required, um, the systems that

support our lives, which of course are the biodiversity,

uh, that we're wiping out. Uh, humanity is very

busily sitting on a limb that we're sawing off.
