Even minor problems of ozone depletion can have major effects. Every time even a small amount of the ozone layer is lost, more ultraviolet light from the sun can reach the Earth.
Every
time 1% of the ozone layer is depleted, 2% more UV-B is able
to reach the surface of the planet. UV-B increase is one of the most
harmful consequences of ozone depletion because it can cause skin
cancer.
The increased cancer levels caused by exposure to this ultraviolet light could be enormous. The EPA estimates
that 60 million Americans born by the year 2075 will get skin cancer
because of ozone depletion. About one million of these people will die.In
addition to cancer, some research shows that a decreased ozone layer
will
increase rates of malaria and other infectious diseases. According to
the EPA, 17 million more cases of cataracts can also be expected.
The
environment will also be negatively affected by ozone depletion. The
life cycles of plants will change, disrupting the food chain. Effects
on animals will also be severe, and are very difficult to foresee.
Oceans
will be hit hard as well. The most basic microscopic organisms such as
plankton may not be able to survive. If that happened, it would mean that all of the other animals that are
above plankton in the food chain would also die out. Other ecosystems
such as forests and deserts will also be harmed.The
planet's climate could also be affected by depletion of the ozone
layer. Wind patterns could change, resulting in climatic changes
throughout the world.
THE FUTURE
ΕΎ Complete recovery of the Antarctic ozone layer will not occur until the year 2050 or later.
