Are some areas lower in oxygen levels than in other areas?

Besides in the city areas where traffic pollution depletes oxygen levels, when its muggy hot and hard to breathe where the clouds hang low in the sky, are the oxygen levels in that area lower?

Creating A Worm Hole?

Can worm hole science be proven on a much smaller scale by using water as an example and spinning it so that the middle does not contain water. If you drop a bead in the center of the spinning water, it will reach the bottom or other side faster than if you dropped the bead in the still water itself. The time it takes to travel to the bottom or out the other side would be significantly faster. We are advanced enough to make this technology in space....not just entangled particles, but spinning them maybe?

Acid Rain

What happens when the clouds absorb enough pollution to kill all the trees on the planet?  Do we become like Mars?
