The planet has. But living organismsâŚnot so much.
Also - how can you not see how manâs activity - which on a geological time scale went from zero to incredibly high in about 0.00000000001% of the earthâs life? Itâs just unreal.
For millions of years of the relatively stable ecosystemâs life - in which this stable system was bothered only by occasional natural disasters (which still will occur BTW, making matters worse) - there were zero cars. Zero mining. Zero factories. ZERO EMMESSIONS other than natural ones.
And now we cover the plate in things that burn carbon and emit gas. Literally cover it.
A two hour time frame movie on the USA taken from space over the course of the earthâs life since our atmosphere stabilized would be one hour, 59 minute and 59 seconds of nothing but the rocky mountains, the great lakes and the mississippi river visible from spaceâŚnight would be completely dark. The last second of the movie and you would see massive cities everywhere, smog that is visible from space and night would be like looking at the stars.
Not really. Rescinding regulations imposed in the last days of the Obama Administration is a far cry from eliminating environmental rules. 40 plus years of environmental regulations that have served us well are still in effect.
