Actually it's caused skin cancer for thousands of years. The hole in the ozone has been almost exclusivly limited to an area over Antarctica, and ozone isn't the only ultraviolet (the wavelength that causes skin cancer) blocker in the atmosphere. There's evidence of skin cancers in dinosaurs, although nothing proven at the moment.

Our skin excretes a large amount of toxins. These toxins in our diet combined with malnurished bodies that can't break down the sun's energy as well, combined with an increase in the sun's strength due to depleting ozone can cause cancer!

Yeah, this is pretty much nonsense. Our skin doesn't excrete "toxins" on a regular basis. Diet has virtually nothing to do with the occurrence fo skin cancer, and as I mentioned, the "depleted" ozone layer has little to do with skin cancer in, say, northern Europe.

I'm sure in the beginning the sun didn't BURN. It was probably more a warm caress, but over time it gets corrupted by us just like everything else. In some countries the local water gives you cancer. I'm pretty sure it didn't used to, but after the nearby plants dump all their waste into the streams you can get the idea...

You're sure? Sure you're wrong? 'Cause you are. If we go back to the "beginnning", the sun's rays were felt even stronger on earth (the strength off the earth is, for our purposes, a constant). Over the last few million years, the atmosphere has changed.
As far as "nearby plants dumping waste into streams", what does water pollution have to do with the depletion of the ozone layer? That kind of conclusion is laughable.
Sorry for the threadjack, but I can't leave this kind of stuff alone...
