Some people say that the main environmental problem is the loss of particular species of plants and animals. Others say that there are more important environmental problems. Discuss both these views and give your own opinion.
According to some people, the extinction of plants and
animals
is the biggest environmental threat we face today. While I do not admit that this
is a major issue, in my opinion, there are even bigger causes for concern.
The loss of some plants and animals
certainly poses a challenge. It will break the food chain and cause problems
. For example
, when predatory animals
like lions and tigers at the top of the pyramid disappear, it will lead to an uncontrollable increase in the number of herbivores. Unfortunately, this
development will hurt farm yield as animals
like deer, rabbits and pigs will become vermin and eat up farm produce. This
will lead to food scarcity all over the world.
On the other hand
, climate

caused by human activity is an even bigger challenge. Due to pollution and the resultant Correct your spelling

leads to more frequent occurrences of droughts and flooding. This
affects food production. Another issue is the health problems
in both humans and animals
. Many forms of birds and animals

such
places are facing various health problems
like asthma and cancer. If the temperatures continue to rise at this
pace, the planet may become inhabitable 2 or 3 centuries down the lane. Obviously, climate
change
is a bigger threat than the extinction of wildlife.
In conclusion, the extinction of wildlife and the resultant loss of biodiversity is certainly a grave issue. However
, climate
change
and the associated problems
are even bigger challenges as they can threaten the very existence of life on the planet.Submitted by mhdshmnsr on
