The New York Times published an article highlighting the schism in the environmental movement between those who choose to fight development of alternative energy programs which may cause some environmental harm and others willing to cede some ground for progress in broader environmental goals. For example, strict environmentalists are fighting against the development of wind power off the coast of Massachusetts as it might alter marine life and kill birds. Other moderate environmentalists, however, believe a few birds and some marine life may have to be lost to make progress on reduction of greenhouse gases, which they feel pose greater concerns.
The more moderate, nuanced approach to the environment will likely find a wider ear in Washington, as an all or nothing tack will not work in a country trying to find cleaner ways to power its needs domestically.
