Wild animals have no place in the 21st century, and the protection is a
waste of resources.
To what extent do you agree or disagree?
The current global extinction crisis is one of the greatest challenges
posed by the rapid expansion of human populations. The protection of endangered
species, as far as I can see, should be a top priority for three main reasons:
economic value, scientific value, and survival value.
Wild animals provide many valuable substances, such as meat, skins and
furs. The financial value of wild species is important to the economies of many
nations. In many countries the recreational viewing of animals at zoos is also a
source of revenue.
The study of wildlife, on the other hand, provides valuable knowledge about
various life processes. Such study has helped scientists understand how the
human body functions and why people behave as they do. Scientists have also
gained medical knowledge and discovered important medical products by studying
wildlife. In addition, by observing the effect of environmental pollution on
wild animals, scientists have learned how pollution affects human life.
Furthermore, every species of wildlife plays a role in helping maintain the
balanced, living systems of the Earth. These systems must continue to function
if life is to survive. Thus, the loss of any species can threaten the survival
of all life, including human beings.
In conclusion, the protection of wild animals in the 21st century is by no
means a waste of resources; on the contrary, its importance should ever be more
stressed by international organizations, government agencies, industry and
individuals for the valuable resources the wild animals provide us and for human
survival. (250 words) |
