Natural rate of extinction is 1 species/day
Man-accelerated rate of extinction is 137species /day (that’s 50,000 sp/year) –current updates say it’s now 20 species an hour. That’s # / yr? _____________
#1 reason organisms are endangered is habitat destruction !
150 acres of rainforest are destroyed each min (that’s like 1-2 football fields a sec!!!)
For every keystone species that disappears, soon follow)
175,000!
