When stratospheric ozone is depleted, the dangers of severe sunburn and skin cancer due to the sun's ultraviolet radiation increase...
...tropospheric ozone levels, in the layer of the atmosphere extending from ground level to the stratosphere, act as a crucial buffer between the earth's surface and the rest of the atmosphere.

Bush ridiculed this threat during the '92 campaign, calling Gore "Ozone Man," but in fact the loss of the world's upper atmospheric shield is one environmental threat that has people genuinely scared...
