So the denier lives until he’s 75. That seems to encourage denial, which I don’t think is the point of the cartoon.
How about this to scare you:
Right now, there are eight tropical storms happening on the planet. One is about to hit Japan and two are headed in the direction of Hawaii. Four are hurricanes (typhoons, cyclones, whatever you want to call them). Notice how they’re all around the red band? That’s because the oceans are warming and that allows the storms to build.
We are on track for the hottest year in recorded history. The coasts are going to be underwater sooner than you realize.
So let’s say some intergalactic alien race, let’s call them Kanamits, came up with a special use for humans and took us all with them to their planet. What would happen to this third rock from the sun?
Well that’s depressing. If humans disappeared, the world would be a better place from nature’s perspective. It wouldn’t take that long: 500 years or so. And 500 years is nothing in the life of a 4.5 billion year old Earth. Hell, 500 years is nothing even if you’re deluded into believing the Earth is only 6,000 years old.
We have doors like this where I work. And people are always doing the wrong thing. But the other flaw with our doors is that if you don’t do certain things in a specific sequence, it sets off an alarm, which annoys everybody in the immediate vicinity.
