I think a million years after we are gone, or even 50 million years, one could find our curious layer in the rocks rather easily. The soils we fertilize, the above ground atomic weapons testing, the enormous amount of coal we burn and the plastic will all leave little clues. I think our impact viewed in the geologic record will be fairly significant. It won't rate up there with the Stromatolites or the Siberian Traps, but I believe we are going to leave a lot more than fossilized bones.
yeah, I agree mostly. good points.
I wonder, though:
Just because we can think about our impact, and,maybe know what it'll do, how will we know if the choices we make are correct? and, correct, for whom?
the big asteroid/comet that hit earth and caused the mass extinctions was a bummer for T-Rex, but, a pretty good thing for mammals and, ultimately, us............
Will the plastic in the layer we leave, end up feeding some microbe that comes and repopulates earth with wise, all knowing, all caring creatures?
I guess all I'm getting at is that all the doom and gloom, back and forth of the different groups, projecting the ultimate outcome of a certain action, or lack thereof, is, IMHO, speculation in the long term.
Many of the "learned, opinionated, influential" people that make proclamations about how we should live and what we should do, feel their "opinions" (which often is just what it is) are sacrosanct.
I feel, do minimal harm, don't waste or be wantonly destructive, but, don't live in mud huts and eat grubs either.........
it seems very ego-centric (if I use the term correctly) to think we are powerful enough to ruin the entire earth, to have such impacts that the earth can't heal. Sure, in the short term views that we have, at most multi-generational, things happen.
But, clearcut a mountain, and, we think it's lost for ever............probably not. but, it is lost for a generation or two.
Does the earth care about 100 years of desolation? I'd look at Mt. St. Helens, and, say, probably not............
wow, I'm rambling.........sorry.........(not so sorry as to delete it, though........grin......)
