But we should. This is a taboo topic but pretending that these consequences are either disconnected from capitalism or that capitalism is some natural law of the universe that should never be challenged is, for lack of a better word, delusional.
These consequences are inherent to capitalism because people benefiting from it demand infinite growth and nobody is incentivized to care about the environment. People who care about it get outcompeted by those who don't in ruthless pursuit of "efficiency".
We can try to regulate it to the point that people wouldn't call it capitalism anymore but the nature of a system where the only incentive is maximizing profit will always have a natural tendency to harm the environment, so it should be disputed.
