Second, with the increase of human activities, modern people take up more and more space. Which has a great impact on other species. Finally, the problem of pollution becomes more and more serious with the development of modern industry. More and more animals have to adapt themselves to the decaying environment or move to a totally different place, but not all of them are fortunate enough to survive the changes.
Solving this problem calls for, above all, the government’s efforts to control population growth, to decrease industrial pollution and to enhance the laws to forbid wildlife hunting. Moreover, common citizens should be aware of this ecological crisis and take on the responsibility of wildlife protection. In a word, only when the government and the common people make joint e f forts can we hope to find a satisfactory solution to this problem.
首先，隨著人口的增長，人們消耗更多的自然資源，這往往導致過度狩獵。其次，隨著人類活動的增加，現代人占據了越來越多的空間。這對其他物種有很大的影響。最后，隨著現代工業的發展，污染問題越來越嚴重。越來越多的動物必須適應退化的環境，或者搬到一個完全不同的地方，但并不是所有的動物都有幸在變化中幸存下來。
解決這個問題首先需要政府努力控制人口增長，減少工業污染，并加強法律禁止野生動物狩獵。此外，普通市民也應該意識到這一生態危機，承擔起保護野生動物的責任。總之，只有當政府和百姓共同努力，才能找到一個令人滿意的解決辦法。
