How come things on Earth don't get sucked out through it?
I know it's only one part of the atmosphere, but in order to damage that, wouldn't things have to get through the outter layers first?

If there's supposedly a hole in the ozone layer...?

Ozone comes from the process where infra red radiation of high energy strikes an oxygen molecule, splitting it in two free oxygen atoms. As they meet other oxygen molecules they recombine into ozone molecules.

"For nearly a billion years, ozone molecules in the atmosphere have protected life on Earth from the effects of ultraviolet rays.

In the past 60 years or so human activity has contributed to the deterioration of the ozone layer. Only 10 or less of every million molecules of air are ozone. The majority of these ozone molecules resides in a layer between 10 and 40 kilometers above the Earth's surface in the stratosphere.

At higher altitudes, where 90 percent of our planet's ozone resides, “good” Ozone does a remarkable job of absorbing ultraviolet radiation. In the absence of this gaseous shield in the stratosphere, the harmful radiation has a perfect portal through which to strike Earth.

At sea-level Ozone is “bad” since it is harmful pollutant. The amounts of "good" and "bad" ozone in the atmosphere depend on a balance between processes that create ozone and those that destroy it. An upset in the ozone balance can have serious consequences for life on Earth."

Ultraviolet radiation is a danger to all living organisms, as well as plants.
Ultraviolet radiation

And the 'hole' they speak of is the absence of those protective molecules stopping the ultraviolet radiation.
