Future of Life [Englisch] [Taschenbuch]

Wilson begins with an open letter to the patron saint of environment defenders, Henry David Thoreau. He offers a comparative view of today's Walden Pond with that of Thoreau's day. Wilson will use such comparisons for the remainder of the book. The issue is clear: humanity has done grave damage to its home over the millennia. The growth of human population, but more importantly, the usurpation of the biosphere for limited human purposes, threatens a world losing its ability to cope with the intrusion. Can this planet, with human help, be restored to biodiversity levels that will ensure its ongoing capacity to provide for us?

Wilson's writing skills readily match his talents as a researcher. Presenting sweeping ideas with an economy of words, he avoids vague assertions or the need for the reader to fill in information. With each stop of our global voyage in his company, he provides detailed information describing examples of human "erasure of entire ecosystems." At this pace, he informs us, we will soon require four more planets of our resource levels to sustain humanity's intended growth. In the classic tradition, he introduces a protagonist for continued economic growth debating an environmental defender. Both views can be accommodated, he assures us, but only if a population limiting bottleneck is achieved. What level of humanity can the planet endure? The numbers frighten, but the resolution, Wilson stresses, isn't inevitable.

Diversity, he argues, is the key. Even our agricultural crops can benefit. A mere hundred species are the foundation of our food supply, of which but twenty carry the load. Wilson counters this precarious situation by urging investigation of ten thousand species that could be utilized. Further, and this point will give many readers qualms, Wilson urges genetic engineering to apply desired traits between crop species. He urges these strong measures as a means of reducing the clearing of habitats to enlarge farming acreage. In conclusion, he stresses the application of ethical values in considering the environment. Each of us must make ourselves aware of our impact on our nest. If you are to survive, it may well rely on whether you read and act on the ideas in this book. Although other works on this topic are available, Wilson's stands above the others for clarity, scope and suggestions for survival. Are you, he asks, willing to add one penny to the cost of a cup of coffee to retain the world's natural reserves? It's the question confronting us all.

It is more easily readable than his more heavily foot-noted and astonishingly deep earlier work, but all the more valuable for its smooth overview of why life on the rest of the planet matters to the American heartland; why we must deal with the limits of food production and control population (both in terms of numbers and in terms of consumption per capita).

The heart of the book, for me, can be found in three profound numbers--numbers that we must all appreciate:

Value of the Ecosystem/Cost to Replace: $33 trillion per year in increased Gross National Product (GNP)--and presumably everything would be artificially recreated.

One-Time Cost of Fund for Preserving Nature: $24-72 billion one-time funding. His numbers vary from $24 billion (one -time) to preserve 800,000 square kilometers already under protection, to $28 billion to preserve a (different?) representative sample. The bottom line: for a one-time $100 billion investment, 25% of what the US spends on its military *every* year, we could, at our own expense, save the world.

Subsidies for Unsound Acts Against Nature: $2 trillion per year and rising ($2000 per American alone--this refers to energy, water, deforestation, and agricultural subsidies that encourage and perpetuate unsound acts against nature as well as unneeded exploitation--one example: $20 billion a year in subsidies for fishing--this is the difference between the actual value of $100 billion and the lower subsidized revenues of $80 billion a year).

Wilson's book, in combination with those by Brian Czech and L. O. Stromberg, is in my view a capstone endeavor that moves the environment to the forefront of any intelligent person's agenda. As he concludes, we have entered the century of the environment--we must save it or lose it.
