The Endangered Species Act has become a blunt instrument that environmentalists and NIMBYs can use to shut down almost any major infrastructure project. No one wants to see any species go extinct but the time has come to make some hard choices. We may have to sacrifice the six-toed purple salamanders or whatever in order to preserve the rest of the biosphere.
We're not really saving these species, anyway. Climate change will eventually come for them. We can either make a few hard choices now or watch as a few... hundred... thousand choices are made for us.
