Dioxin is natural.
Ok, stop reading and go no further. Only if you think you can handle the truth, then you may proceed.
Very well. You were warned...
If you don't believe in God, and you are pretty sure that UFOs didn't plant Humans on this earth, then Humans are just as natural as a snail darter, or a spotted owl. We maybe over populated, but it's a natural occurrence.
We evolved on this planet, just like every other critter, and everything we create from artwork, to Toxic waste is as completely natural as a bird nest. We are just animals, no more, no less. If we create nuclear weapons and atomize the earth, then it is as natural an event as lemmings running off a cliff. It doesn't matter if lemmings don't destroy the planet. It is still a naturally occurring event, because we are just dumb animals..
If we cut down every inch of rain forest, don't blame us, we are just animals. It's our nature. It's a perfectly natural event.
You may think, I'm and idiot, but I challenge you to refute the evidence above.
It doesn't matter, if we are smart enough to prevent this. If it happens, then obviously we aren't that smart. Either way, that is not the argument. The argument is that since we as human animals evolved on this planet and are indigenous to it, with no help from a God, Spirit, or other super-human being, then anything that happens to us is NATURAL..
