> Since when is "assigning virtuous environmental brownie-points" the topic of discussion?

I think it's very straightforward. Here's a recap of the thread, you can see it in the quote for the first item:

1. khanhnguyen8386 implied that they were "sophisticated ecosystem engineers, shaping the rainforest for centuries without destroying it."

2. smt88 challenged that by pointing that 97% of "the rainforest" was probably untouched by this group, as opposed to shaped deliberately.

3. I (Terr_) chime in to emphasize that we shouldn't assume a region was intentionally left-alone when the much simpler explanation is that it wasn't practical to exploit it.

You have also confused me with some other user.
