Caitalism and Democracy do not make good bed fellows. Democracy requires power to be or seem to be vested in the populous though various related systems. Capitalism requires power to be vested in a few with the goal of profit. Democracy is public, capitalism is private.
Ummm..... not quite. Democracy requires political power to be vested in the populous. Capitalism requires the ownership of productive assets to be predominantly in private hands. They aren't necessarily incompatible. The fact that you own a farm or a factory doesn't mean that I don't get to vote.
They can coexist reasonably happily. There have been countries that are both broadly democratic and broiadly capitalist that have existed and prospered for a long time.

Saving the planet is almost impossible with Capitalism.
As opposed to what alternative? The Soviet Union and East Germany weren't capitalist, but didn't exactly have stellar environmental records.
If you think the planet can't be "saved" (whatever you mean by that?) is private ownership of assets is allowed, then what better system are you proposing?
