More UV radiation will reach the surface of the planet. The Kyoto Protocol is an international attempt to limit the production of greenhouse gases. . Greenhouse gases bounce heat back to the surface of the Earth, rather than allowing it to escape into space. Computer models of the Earth's atmosphere are used by meteorologists to predict the temperature of the Earth's atmosphere in the future. Ozone depletion is greater over the Arctic than the Antarctic.
Ozone depletion allows higher levels of UV radiation to reach the Earth's surface.
The Montreal Protocol is an international agreement to limit CFC production. Industries producing CFC's responded quickly to develop alternative chemicals when it was learned CFC's were involved in ozone depletion. Increased incidence of cataracts in vertebrates. Damage to the DNA of the eggs of some frog species. Expansions of the geographic ranges of some species.
