David Attenborough is very gloomy about
much of what he's seen. What's depressed
him most has been the huge speed and
scale of change that human beings are
inflicting on the world. People destroy
everything around them. For example they
cut down forests just because they need
firewood to keep warm. And they don’t
think about the future. When they cut
down forests, the good soil have no
umbrellas to protect them from the heavy
rains. Water washes all good soil and in
the future we will have no soil, no
forests. Every year people destroy about
29,000 square miles. That is an area the
size of the whole Scotland disappearing
every year. Forty per cent of our drugs,
our medicines, are derived from plants
and most of those come from the tropical
rain forests, and most of those come
from the Amazon. But if nothing will be
doing Amazonian jungle will disappear
in just few years. Trees are a vital
part of the water cycle, and of course
they give us the oxygen. That means that
we’ll have nothing to drink, to eat and
no oxygen to breathe. Cutting down
forests also causes floods. But we can’t
say to these people that they mustn’t
cut down that tree in order to cook
their food. And it is an important
problem of mankind – thinks David. But
there are also other environmental
problems today. Some of these problems
are : the ozone holes, global warming (
or green-house effect ), acid rain … And
the tragedy is that the people who
suffer first are the deprived people,
the people who are living on the edge of
prosperity. And if they think that they
are insulated from that, they are wrong.
I think now a lot of people are
beginning to realize that environmental
problems are not somebody else’s. They
make different organization, whose aim
is conservation. For example “ GREEN
PEACE ” , “ FRIEND OF THE EARTH ” and
others. Everyday millions people from
all over the world do everything to
protect our environment , and they need
for our help. I think we ought to help
them , just to make our future better.
