You're confounding two separate issues.

One is preserving the environment, often (global warming, ocean acidification, mercury pollution, acid rain, background radiation elevation, plastics pollution, ozone depletion, antibiotics overuse) in ways which affect the global environment and pose existential risks to all of modern civilization, if not humanity.

The other is equity and fairness.

Achieving a few years or decades of growth to lose it all really doesn't strike me as particularly rational behavior.

Addressing the whole scope of challenges facing the world is going to be exceptionally difficult.
