Do you think that saving the world is a lost cause?

People keep campaigning for the rest of the world to try save the planet but do you think that it is pointless? Or is it just that people are sitting back and letting everyone else do the job for them? Personally i think that changing the collective lazy attitude towards saving the environment to enthusiasm is the first step before people solely focus their energy on trying to save the planet. I mean that it’s fine that people are trying to help the environment, but wouldn’t it be better for them to try get everybody enthused about doing it so everybody can help make a difference?
