The 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.

Humanity is exalted not because we are so far above other living creatures, but because knowing them well elevates the very concept of life.

These slender little people (Homo Habilis), the size of modern 12 year olds, were devoid of fangs and claws and almost certainly slower on foot than the four legged animals around them. They could have succeeded in their new way of life only by relying on tools and sophisticated cooperative behavior

Biophilia, if it exists, and I believe it exists, is the innately emotional affiliation of human beings to other living organisms.

Sstudying ants just quickly became part of me because I was allowed to wander, explore and find things and figure things out myself. And I saw how much was there and what could be done and how I could make a life of it.

Biological diversity is the key to the maintenance of the world as we know it... Eliminate one species, and another increases to take its place. Eliminate a great many species, and the local ecosystem starts to decay.

Biology is a science of three dimensions. The first is the study of each species across all levels of biological organization, molecule to cell to organism to population to ecosystem. The second dimension is the diversity of all species in the biosphere. The third dimension is the history of each species in turn, comprising both its genetic evolution and the environmental change that drove the evolution. Biology, by growing in all three dimensions, is progressing toward unification and will continue to do so.
