>Capitalism is the root cause here.
That is not how capitalism works, it works by providing value to the greater whole of people, that's how it obtains money. If a business isn't doing something we like, we don't purchase products, services, advice, etc. or at least that's how it should work. The bigger problem is why do we value the wrong things? or why are we unable to develop better solutions?
I agree there are things we can improve about the environment (for example plastic in oceans, etc.) but saying capitalism is the root cause is foolish and unsubstantiated.
