To be anthropocentric is to remain unaware of the limits of human nature, the significance of biological processes underlying human behavior, and the deeper meaning of long-term genetic evolution.

The global conservation organisations are doing everything they can on modest budgets. They essentially promote setting aside reserves and parks around the world.

We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity.
