I don’t disagree with you, but this is unrealistic.

But…we don’t have a choice if we are to survive. Continuation with any system like our current system (i.e. exploitation of nature for economic growth) will lead to obvious ecological collapse. Why is certain ecological collapse viewed as the more realistic choice?

This is akin to a person well on their way to a heart attack saying “well, eating healthy is unrealistic, so let’s switch to diet coke and pretend that’s enough”
