The number one way to prevent water pollution is to not dump waste materials into bodies of water. You can also clean street trash to prevent it from blowing into the waters.
The thermosphere is the first layer of the atmosphere where there are enough heavier molecules (oxygen) to absorb a significant anount of the Sun's radiation. Below the thermosphere, much of the heat is dissipated by convective currents.
Although technically "hot", the gas in the thermosphere is so thin that it can pass little heat to other molecules, and loss of heat by radiation would still cool objects in this part of the atmosphere.
the sun's radiation strikes it first
Chlorofluorocarbons damage the protective ozone layer.

IT is closest to the sun
Aurora Borealis is caused by particles hitting earth's atmosphere thermosphere and they are stopped, so they give of their energy in the "Northern Lights" or Aurora Borealis.
An increase in skin cancer can be trace to a decrease in atmospheric ozone.
