The
loss of outdoor sports
The release of greenhouse
gases into the atmosphere has led to
some dangerous consequences such
as depletion of the ozone layer
that surrounds the earth and protects
us from harmful UV rays that can
cause cancer. Over the last 200
years the ozone layer in Antarctica
in spring has fallen by up to
40 percent. This is largely due
to the release of man-made chemicals
such as Chlorofluorocarbons (CFC).
In the southern hemisphere the
situation has reached the point
where it is unsafe to go out at
certain times of the day. The
possibility of enjoying outdoor
sports and recreation is vanishing
along with the ozone layer itself.
The
loss of mountain ecosystems
Deforestation:
Mountain ecosystems are being
destroyed, threatening the very
existence of animal and plant
populations. Mountain are not
just lifeless snow-covered rocks,
they support unique varieties
of fauna and flora. Felling trees
destroys their habitats and allows
soil erosion from rainfall. Mountains
are an indispensable feature for
over half the world's population - from the waters that flow down
to their effects on climate, their
destruction will effect our lives
and reduce the possibility of
enjoying hiking, trekking, climbing,
alpine sports and other mountain
activities.
The destruction of ocean ecosystems
Sea
pollution: Through pollution and
development, the oceans have reached
a critical state. The oceans are
very adaptable but through our
endless xploitation of the oceans
we've pushed their limits. In
parts of the world it is not safe
to swim in the seas, and the possibility
of enjoying swimming, surfing,
windsurfing or fishing is ever
decreasing.
