Quote Me, Quote You

There's so much pollution in the air now that if it weren't for our lungs there'd be no place to put it all.
- Robert Orben, magician (b. 1927)

I think this is the natural progression of evolution (the survival of the fittest, if you will), wherein only the organisms that adapt to their surroundings stand a chance to continue their stay on earth.

Several centuries from now, human lungs would have built-in air filters to process the air they breathe. If we transport a present-day dude 400 years into the future, his lungs won't be able to handle the airborne toxins considered "normal" to creatures of the era.

That eerie thought reminds me of Avatar. And it reminds me why I am afraid of the idea of time travel.
