Opinion: Biodiversity crisis threatens humankind

Golden toads were discovered in Coata Rica in 1966. None have been seen since 1989, despite intensive surveys. They are presumed extinct. PHOTO COURTESY U.S. FISH AND WILDLIFE SERVICE.

It’s Endangered Species Day, so hug a boreal toad (if you can find one)

By Bob Berwyn

SUMMIT COUNTY — May 20 is Endangered Species Day, a good time to consider that the global wave of species extinction currently under way threatens human existence in ways we can’t even begin to understand.

It’s time to get serious about protecting habitat on a global scale to try  and preserve as many species as we can. At the same time, we have to put forth every effort to try and understand those species. Until we do, we’ll be “flying blind in the biosphere,” as biologist E. O. Wilson said.

Here’s a bit more from Wilson, the pre-eminent scholar in the field of biodiversity. I’m using a big quote because he is so much smarter and more eloquent than I am.

“How can we fully understand the ecology of a pond or forest patch without knowledge of the thousands of species–indeed millions when bacteria are included–the principal channels of materials and energy flow? How can we anticipate and control the spread of new crop diseases and human diseases if we do not know what they might be, or the location of their endemic reservoirs, or the identity of the insect and other vectors that carry them? And, finally, and I mean finally in the literal sense, how can we save Earth’s life forms from extinction if we don’t even know what most of them are?”

There are hundreds of species of plants and animals already listed as threatened or endangered, and another 330 species in the U.S. deserving of protection that have yet to be placed on the endangered species list.

There are 74 animals on the Colorado endangered and threatened species list, including 19 birds, 23 fish, and 14 mammal species. Click here to see the full list.
