And inside a chain-link pen covered to keep out predators are scores of rare, threatened, sand-colored desert tortoises.
Their captivity helps show how complicated it is to combat climate change without collateral damage. The foot-long (30- centimeter) creatures are being removed from their burrows for a project to harvest solar energy in the California desert. Trucks groan down sunbaked roads, cranes pivot with 750-pound (340- kilogram) mirrors and mechanical post-pounders drive steel pylons into the packed desert floor, destroying their habitat.
Construction of such large-scale green-energy projects has splintered environmental groups. When concern over global warming was at a peak, national organizations such as the Sierra Club and the Natural Resources Defense Council threw their support behind industrial-scale wind and solar installations on public land. Now some smaller conservationist groups object to what they consider an environmentally destructive gold rush.
