Does human harmed the Earth or make it a better place to live?
I think that people have not been thinking about saving the world
they live in and have been damaging it for a very long period of
time. And now many international organizations are doing their
best to heal the `wounds` of the Earth.
Since scientists discovered that there is a hole in the Earth`s ozone
layer we have been trying to find out which of people`s activities
harm world and whether it can be undone. Since this terrifying
discovery new ozone friendly deodorants have been invented. They
are becoming more and more popular every day because people do
care about the destiny of Earth and they do not want to be “baked”
by the solar energy.
Another problem that we have caused to the world is cutting of
forests. Every little child studies at school that forests are the lungs
of our planet and we are taught that it is very good if in our life we
plant at least one tree. Many hectares of forests are being cut just
because a fat businessman has decided to build there either a
supermarket with parking lot, or a highway.
Next comes the problem with the nuclear energy. Are these nuclear
power stations as important as it is stated? Is there a completely safe
nuclear fusion used in these power- plants? No, there is not. Many
people still remember the tragedy on 26 April 1986 called
Chernobyl. And nobody wants it to happen again.
If my statement that people harm the Earth is not true how can we
explain that new things are being invented just to stop or slow down
the Earth`s destruction?
