Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

What Migeru said. I'd add that any core sample through the right layers in seabed sediments or (much later) rock would show clear markers of chemicals, soot, and strange particles of various sorts.

"The sad truth is, once the humans get out of the picture, the outlook starts to get a lot better..."

The collision of human beings with the natural biosphere is ugly, getting worse, and has enormous momentum. Looking at what's already happened, consider that agriculture has consumed enormous areas, and that it has (of course) selectively destroyed regions of high biological productivity. For similar reasons, we tend to think of "primitive" people as living in hostile environments -- the arctic, deserts, mountains, hell-holes of tropical disease -- but this is because the nicer places were quickly grabbed by more powerful cultures, and largely for agriculture.
