The future of life
The book starts with a look at the breadth of life on Earth and then goes on to look at population growth, and what resources are available to support it. This is followed by chapters on habitat destruction and species extinction. Wilson then examines the different ways of assessing the value of the biosphere for humanity. The final chapter considers what can be done about the problem, drawing on Wilson's extensive involvement in the area.
Following the furore over Sociobiology, it is interesting to see how Wilson is much more tentative about such ideas, and clearly wants people to see what he really considers to be important.
