Yeah-buts know when things are bad for the environment. They know about the dangers of throwaway plastic, whether it be bags, straws or bottles. They know that eating farmed meat, leaving the tap running, and driving cars powered by fossil fuels are not good for the world we live in.

They know this situation is not sustainable and that someone must do something about it. They might even be willing to make an occasional donation to an environmental charity. But ask them to take action themselves, especially if that involves even a low level of inconvenience, and the Yeah-buts sound their call.
