But much of today's controversy revolves around the preservation of species and habitat, or biodiversity. What I should have done is repealed the whole Endangered Species Act. Before anybody realized what had happened. Unless land-use policies that are driving salmon to the brink of extinction are changed, we will lose 9 out of 10 salmon species. And they are disappearing in record numbers.
Habitat fragmentation is one of the key problems.
Where development has replaced flowers and fields with spans of concrete, energy depleted pollinators are starving to death. Hopefully, that is not a portend for our own species. Here's another agricultural imperative for the preservation of habitat. It is estimated that as much as one fifth of the world's cropland is suffering from some form of radical deterioration. Arable land and topsoil are limited global resources.
