David Attenborough
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.
