Everyday, animals are becoming extinct throughout the world. What do
you think the causes of this are? What solutions can you suggest?
Nowadays,
there are many wild animals are under threat of extinction. Although
occasionally some species disappear from the Earth naturally, the causes of
this phenomenon are mainly human activities. Humans, the smartest species in
the world, must take responsibility for this loss.
The
most important reason is widespread deforestation. People cut down trees
haphazardly, especially in developing countries. As we know, the number of
species living in forests is much more than in any other habitats.
Unfortunately, almost all forests are belonged to poor and developing countries
such as countries in South America, South Asia and Africa .
These countries consider forests as one of the most important natural
resources. They cut down trees to export timber to rich countries and import
basic goods such as food, drugs… Because it is very difficult for these
countries to escape from the cycle of poverty, they still continue deforesting
as a way to earn their living.
The
other reason is the rising of the world population. It leads to many problems.
Firstly, people need more space to live or to build their houses, so they
invade habitats of wildlife species. Secondly, in order to supply enough food
to seven billion people, they must exhaustively exploit the nature. They hunt terrestrial
animals on lands, catch fishes in the seas and trap birds. They do all possible
manners to satisfy human needs without worrying about the stress of nature.
There are many animal species become extinct and endangered because of illegal
hunting activities.
The
development of industry is also a main reason; it connects with the rising of
the world population. The more they develop industry, the more natural
resources they need to operate and the more waste they discharge into the
environment. Therefore, many species, also comprising human, are suffered from
toxic substances; thus, the number of individuals of certain species has been decreasing to levels of extinction. Industry also discharges carbon dioxide and
other gases into the air. People believe that these gases cause two serious
environmental problems called green house and climate change. These phenomena are
leading to a great change of natural environment in the world. On one aspect, the
temperature is gradually increasing; it makes ice on mountains and poles melt,
thus the sea levels also are rising. Some coastal areas will be flooded under
seawater, so species in these areas will loss their habitats and become fewer.
What
can we do to protect wildlife animals? Firstly, I think rich countries should help
poor countries create some nature reserves and develop their own economies.
Countries having nature reserves can develop the tourism industry. If the lives
of the poor become better, they will not need to deforest and hunt animals in
order to earn their living. Secondly, governments should improve knowledge of
people about this problem through education and mass media. Thirdly, we need to
use natural resources more wisely and stop poaching.
