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, but the causes of
this phenomenon mainly are human. We, the smartest species in the world must
take responsibility for this loss.
The most
important reason is widespread deforestation. People cut down tree 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 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 to these countries to escape from the cycle
of poverty, so they still continue deforesting as a way to earn their living.
The other
reason is the raising 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 around seven
billions people, they must exhaustively exploit the nature. They hunt terrestrial
animals on lands, catch fish in seas and trap birds on the sky. They do all
possible manner to satisfy human needs without worrying about the stress of
nature. There are many animal species becomes extinct and endangered because of
human hunting.
The
development of industry also is a main reason, it connects with the raising of
the world population. The more they develop industry, the more natural
resources they need to operate and the more waste they discharge to the
environment. So, many species, also comprising human, are suffered from toxic
substances, thus the number of individuals of certain species has decreasing to
levels of extinction. Industry also discharges carbon dioxide and other gases
to the air. People believe that it causes 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 mountain 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 the rich countries should help the poor countries to create some nature reserves and help them develop their
own economies. Countries having nature reserves can develop the tourism
industry. If the life of poor people becomes 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
other mass media. Thirdly, we need to use natural resources more wisely and stop
poaching.
