"Save the PLANET?!?!?...folks, the planet ain't going anywhere....it was here a long time before us and it will be here a long time after us...the PLANET is fine, its not going anywhere...WE ARE! And after we're gone, the Earth is going to shake us off like a bad case of fleas..."
I just can't get too upset about our plight because 99.9% of every species that EVER lived on this planet - animal, plant, bacteria - is already extinct and pretty much all of the species around today won't be here as soon as 100,000 years from now. Once humanity gets done poisoning itself and the rest of the organisms unfortunate enough to come on the life stage at the same as us, the Earth will pause, reset and go on.
Comets, volcanos, Ice ages and Tropical poles, mass extinctions on several occasions...acidic oceans, carbon dioxide levels that we are going to see again soon...glaciers that once carved as far south as Indiana and left the Great Lakes, inland seas that have come and gone and left chalk deposits as a grim headstone of sorts....impact craters like the majority of the Gulf of Mexico....none of this could extinguish life on Earth and neither will we.
Humanity itself is doomed because of greed and stupidity; but life on Earth will go right on cycling through emerging species and extinctions until the Sun eventually burns out and consumes the entire inner planetary system as far as Mars.
But don't fret...if you run the clock forward enough, the entire universe seems destined to die a long, slow heat death anyway! Happy Wednesday!!
