7. Thanks again.

First, I don't know that the idea of green growth can be proven (or disproved) in a scientific sense. It's a question of what the preponderance of evidence that we currently have indicates. So far, there is zero evidence that economic growth can be sufficiently detached from material throughput. Perhaps that will change, but the consequences of pursuing economic growth HOPING that things turn out otherwise would be catastrophic.

Based on my reading (from multiple sources), there seems to be a rough consensus on what the various categories of planetary boundaries are, although there is not a consensus on what the limits are for a few of them. I've seen different terms assigned to the categories, but they're usually described something like this: climate change, land use, freshwater use, ocean acidification, biodiversity loss, nitrogen & phosphorous loading, ozone depletion, chemical and air pollution. There are a lot of articles, papers and books out there about this; here's one: https://science.sciencemag.org/content/347/6223/1259855

My thoughts about your #3 point are similar to my thoughts about your #1. Scientific "proof" for a question as complex as this is a pretty high bar. What we can do is observe our current trajectory with respect to planetary boundaries and note the correlation to growth in global GDP. The consequences of erring in one direction are pretty severe, and the consequences of erring in the other direction aren't.

Finally, I don't think it matters in the least what Bill Gates knows or doesn't know, or what he believes. No doubt Hitler thought he was doing the right thing...
