Why?--to all in this thread. I do not understand.
Since this appeared, 7.54 million years ago,

.......we have risen to the top of the food chain on this planet. We also have had little impact to the rest of the world, outside the 11 major cities on Earth, which holds 90% of the planet's population and other than Europe and the USA, the Earth is a very very empty place of people--(Example: Patagonia, the size of the USA; pop: 1840). Thus, we are here.
If Extinction is a goal, there are vehicles for that on local-- it is called suicide.
Just a thought.
