Now when you cut a forest, an ancient forest in particular, you are not just removing a lot of big trees and a few birds fluttering around in the canopy. You are drastically imperiling a vast array of species within a few square miles of you. The number of these species may go to tens of thousands. Many of them are still unknown to science, and science has not yet discovered the key role undoubtedly played in the maintenance of that ecosystem, as in the case of fungi, microorganisms, and many of the insects.
E. O. WilsonIf we lose half the species, which could happen by the end of the century if we don't do anything, that's going to create a big difference down the line in the stability and even the economic potential in the living world. Irreversibly.
E. O. WilsonWe have to create a sustainable environment, worldwide, and we're not doing it. The best thing we can do with the rest of this century is aggressively acquire - and put aside - the richest natural reserves that we can, and then do our best to manage the needs and desires of the 11 billion people we expect to have by the end of the century. This is where biology is headed. For that reason, the sooner we get on with mapping biodiversity on Earth, the better off biology will be - not to mention the whole subject of saving it before we carelessly throw it away.
E. O. WilsonThe one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.
