Is there a body of thought that links global population growth and declining biodiversity with karma and reincarnation?

Recently a family member was explaining to me her particular Buddhist doctrine and mentioned (in the context of karma and reincarnation) that it was somewhat a rare experience to be born human. Somewhere that got me thinking about whether (in this context) the global population explosion and the decline in biodiversity is an indicator that we as spiritual beings are simply moving up the karmic ladder—that we’ve been around long and well enough to move up from animals to humans.

Obviously, you are welcome to agree or disagree with this idea to your heart’s content, but my main question is whether there’s any substantive writing out there pertaining to this idea.
