The historical circumstance of interest is that the tropical rain forests have persisted over broad parts of the continents since their origins as stronghold of the flowering plants 150 million years ago.
Ants make up two-thirds of the biomass of all the insects. There are millions of species of organisms and we know almost nothing about them.
People need a sacred narrative. They must have a sense of larger purpose, in one form or another, however intellectualized. They will find a way to keep ancestral spirits alive.
The biological evolutionary perception of life and of human qualities is radically different from that of traditional religion, whether it's Southern Baptist or Islam or any religion that believes in a supernatural supervalance over humanity.
In many environments, take away the ants and there would be partial collapses in many of the land ecosystems.

The two major challenges for the 21st century are to improve the economic situation of the majority and save as much of the planet as we can.
I tend to believe that religious dogma is a consequence of evolution.
I had in mind a message, although I hope it doesn't intrude too badly, persuading Americans, and especially Southerners, of the critical importance of land and our vanishing natural environment and wildlife.
When you get into the whole field of exploring, probably 90 percent of the kinds of organisms, plants, animals and especially microorganisms and tiny invertebrate animals are unknown. Then you realize that we live on a relatively unexplored plan.
I grew up as a Southern Baptist with strict adherence to the Bible, which I read as a youngster.
Well, let me tell you, ants are the dominant insects. They make up as much as a quarter of the biomass of all insects in the world. They are the principal predators. They're the cemetery workers.
So in my freshman year at the University of Alabama, learning the literature on evolution, what was known about it biologically, just gradually transformed me by taking me out of literalism and increasingly into a more secular, scientific view of the world.
Religious beliefs evolved by group-selection, tribe competing against tribe, and the illogic of religions is not a weakness but their essential strength.
