Since the Endangered Species Act became law in 1973 under President Nixon, over 1,600 species have been put under its protection, and they are all still with us.
The California condor, humpback whale, bald eagle and grizzly bear have been growing in number, as well as some plants and insects. However only 51 are considered recovered sufficiently to be delisted.
There are good conservation practices that can be followed that let development occur and endangered species survive.
However, our current Trump administration and Secretary of the Interior Ryan Zinke are auctioning off tens of millions of acres for gas and oil development and planning for removal of protections for endangered species on those lands.
In 2018, House Republicans have offered up 18 bills aimed at weakening this very effective act.
