Is the environment a moral cause?

Where liberals view environmental issues as matters of right and wrong, conservatives generally do not….People think quite differently when they are morally engaged with an issue. In such cases people are more likely to eschew a sober cost-benefit analysis, opting instead to take action because it is the right thing to do. Put simply, we’re more likely to contribute to a cause when we feel ethically compelled to. – Robb Willer, NYT
