It will. I've said for a very long time that we can simply choose to drive whatever we want, or use coal or anything like that as long as we're willing to reduce our global population by at least 1/10th and keep it there first. Even better if we get it down to 0.5BB.
I don't know if you ever had an opportunity to accidentally overgrow petri dishes, or tissue culture plates... I did it plenty of times in my youth. It's most visible with tissue culture media. You have to constantly change out the media, because the waste products of the cells literally change the environment. Without our intervention, they overgrow, contaminate the micro-environment they are in, and ultimately kill themselves.
Same thing actually happened with our planet 2.4 billion years ago when anaerobic bacteria polluted it with a waste product (oxygen)
