〖首段〗 背景介绍 + 作家立场
Alarmingly，although the economy keeps on prospering, we have been facing a number of environment-related issues such as air pollution, the depletion of various natural sources. Meanwhile，some improper human activities such as hunting rare animals or conducting animal experiment have been exerting a harmful impact on many precious creatures. This essay aims to prove that the government and every individual should make joint efforts to protect the plants and animals.
Virtually, we should never underestimate our efforts in preserving animals and plants. First，biodiversity is one of human beings’ greatest assets because the disappearance of wild animals might trigger some problems. For example，the decrease of owl will lead to the multiplication of voles that are big eaters of crops. Even worse, a many species such as Tibetan antelopes or Manchurian tigers cannot escape the destiny of being killed. Considering biological diversity is a key factor in maintaining ecological balance, it is high time we took effective measures to safeguard animals. Also, some of our improper behaviors in hurting the natural environment, to some extent, ruin our own living space. Over-industrialization and deforestation can serve as convincing examples. Hence, efforts should be made to preserve the natural reserves and thus realize the sustainable development of natural resources.
Others, however, might think differently. Some people might argue that our endeavors in rescuing endangered animals and protecting wildlife habitats are trivial because what is done cannot be undone. Another argument hold by some people is that we have more pressing social problems that need to be given priority to. What I want to refute, however, is that the protection of creature and addressing social problems is not mutually exclusive as long as governments properly allocate financial budget.
Overall, a proverb can justify my stand, namely, a stitch in time save nine. It is the unshakable obligation of governments to protect animals and plants. This wise option can help us utilize natural resources maximally, which can benefit our generations in the long term.
