“The Death of Environmentalism” has stimulated a lot of debate, and not just at tables where environmentalists gather. It asks questions that are legitimate and necessary to consider: how to fight Wal-Mart, how to win universal health care, how to create a world of limitless opportunity instead of widespread hunger and disease. It suggests the need for a completely new approach to combating global warming -- an approach that must reach across the planet to address megacorporate power, economic interests, cultural differences, and individual expectations.
