I mean, shrinking the population would absolutely help assuming that you shrunk it enough.

It’s hard to destroy an environment when the destroyers dont exist.

Sure, or we could just ban super yachts, private jets, cruise ships and empower those indigenous communities who have had such meaningful successes to spread their ideas and understanding so that we can begin to develop a sustainable culture, and we don’t need to kill half the worlds population.

¿por que no los dos?

Also, not half the population, more like 99.9% of it. Start with the richest first, and work your way down.
