I still don't see what is bad with the idea to try and change the environment for the better – this is one way of doing so
Only for the wealthy? It's not some luxury boat we're talking about. But for the feel-good middle class perhaps?
And I always think it's good when people care even if their "one person action" doesn't change the world, many people's personal action together can – at least somewhat.
That's the idea. Lots of "little bits" add up.
