The world's population has increased by about three billion since 1968 and it's getting uncomfortably crowded. In their new book, the Ehrlichs step back and analyze the big picture, looking carefully at how humans have evolved, and in the process how we are laying waste to the planet. As biologists, they are particularly concerned about the sixth major extinction: humans wiping out other species. But they explore all the other problems such as dwindling energy resources including peak oil, poverty, looming water shortages, toxification of the world, and atmospheric degradation including global warming.
They conclude that cultural evolution has not kept pace with technological progress, and that for solutions, humans should look to social changes, including improving governance and eradicating poverty, rather than counting on miracle technological fixes.
When I interviewed Ehrlich, he said, "We need to vastly improve human ethics and re-design North America around people, not cars and possessions." Dominant Animal is a compelling book by two scientists who have spent their lives studying human population, its development and the impact on the environment. We should listen to them.
Let me know what you think about Dominant Animal.
