Looking around it seems to me these are failures of government and government policy (i.e. failures of the people - I can't even convince people to stop buying plastic bottles of water) . Capitalism and businesses operate within the context of the environment they're in.

China has lots of environmental problems and they have an autocracy. Maybe the less capitalistic you country is the less environmentally friendly your country is instead. One has to think that to the extent that resources aren't subjected to the tragedy of the commons, capitalists tend to be concerned with not killing the golden goose.

Look around and ask yourself which countries are at least on paper most concerned with the environment and then ask yourself what kind of economies they have.

Look at Europe: Norway, Switzerland, Sweden, United Kingdom, France, Denmark, Belgium, etc... -> all highly concerned with the environment and all highly capitalist countries.
