Resistance to Change

In today's New York Times there is an article Green Development? Not in My (Liberal) Backyard which discusses an interesting phenomenon. People claim to care about the environment, but when it actually comes down to making sacrifices or changes in order to protect and preserve the environment, many people resist and oppose the changes. This article focused specifically on how this is common in liberal areas that claim to care the most.  This is an interesting conundrum. Does this mean that people support the environmental cause, as long as this support does not necessitate changes in their own daily lives? And if it does, what does this mean for environmentalism?
