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.
