I'm neither a politician nor a celebrity, I'm just an ordinary working man who understands the folly and tragedy of a human-created mass extinction event.
Every 100 million years or so.
Don't you realize how long that is? Humans have only been here for a relatively short period of time.
That doesn't mean we should have a man made extinction. The solar system is more stable now, fewer comets than there were. Over the past 65 million years, many have crashed into the gas giants (Jupiter and Saturn) due to their much higher gravity than earth.
And there won't be another supernova close enough to damage the earth for at least 10 (probably 100-200) million years. Mu Cephei, NML Cygni and VY Canis Majoris will be a bright as a full moon when they explode, but are too distant to destroy most of the life on earth.
Some life forms like Sharks, which evolved some 420 million years ago survived FOUR of the FIVE major extinctions (late Devonian, end Permian, Triassic/Jurassic, Cretaceous-Paleogene).
But Sharks will not survive the 21st century if current declines in ALL shark species continues.
