Answer to 'Preserving natural ecosystems?'

Abstract

I’d like to contribute to preserving natural ecosystems and biodiversity. Has there been an investigation into effective ways to do so? If not, is there a process for funding such an investigation? My perspective is that ecosystems are impossible to regenerate (in reasonable time) once they’re gone and they support many generations of life. I understand that climate change is somewhat correlated, but we could fix climate change and still destroy ecosystems, and vice versa. I found one post from 2 years ago asking something similar, but without an actionable answer.
