在浩瀚的宇宙中，有一颗美丽的星球，之所以它会显得这样美丽，是因为那复杂多样的生物链使它富有生机，富有力量。但是，如果我们的生物链被毁坏，那在这无穷无尽的宇宙中还是否可以找到这颗美丽的星球呢？

In the vast universe, there is a beautiful planet. The reason why it looks so beautiful is that the complex and diverse biological chain makes it full of vitality and strength. But if our biological chain is destroyed, can we find this beautiful planet in this endless universe?

从古到今，世界上的所有生物都是相互依赖，共同存亡的，因此，1927年时，英国动物学家埃尔顿首次提出了这个名词“生物链”。那究竟什么是生物链呢？通俗地讲，就是由动物、植物和微生物互相提供食物而形成的相互依存的链条关系。而这，在生态学上就被称为生物链。

From ancient times to the present, all living things in the world are interdependent and exist together. Therefore, in 1927, British zoologist Elton first proposed the term "biological chain". What is the biological chain? Generally speaking, it is an interdependent chain relationship formed by animals, plants and microorganisms providing food for each other. This is called the biological chain in ecology.

生物链的毁坏，首先是因为它的自然原因。，就比如，如果一种有毒物质被被草吸收，虽然含毒量浓度很低，不影响草的生长，但兔子吃草后有毒物质很难排泄，当因为它经常吃草，有毒物质会逐渐在它体内积累，而鹰吃大量的兔子，有毒物质会在鹰体内进一步积累。因此食物链有累积和放大的效应。

The destruction of the biological chain, first of all, is due to its natural causes. For example, if a toxic substance is absorbed by the grass, although the concentration of the toxic substance is very low and does not affect the growth of the grass, it is difficult for the rabbit to excrete the toxic substance after eating the grass. When it often eats the grass, the toxic substance will gradually accumulate in its body, while when the eagle eats a large number of rabbits, the toxic substance will further accumulate in its body. Therefore, the food chain has the effect of accumulation and amplification.

美国国鸟白头鹰之所以面临灭绝，并不是被人捕杀，而是因为有害化学物质DDT逐步在其体内积累，导致生下的蛋皆是软壳，无法孵化。

The extinction of the American national bird, the bald eagle, is not caused by human killing, but because the harmful chemical DDT is gradually accumulated in its body, resulting in the laying of eggs are soft shells, unable to hatch.

由此可见，一个物种灭绝，就会破坏生态系统的平衡，导致其物种数量的变化，因此食物链对环境有非常重要的影响。

It can be seen that the extinction of a species will destroy the balance of the ecosystem and lead to the change of the number of species, so the food chain has a very important impact on the environment.

生物链的毁坏，还因为人类的参与。也许，在许多人心中，我们所做的种种行为都是在保护那一些动物，但是，一些不恰当的行为却起了“越帮越忙”的反效果，1907年美国人在开巴高原所做的事情就是一个很好的例子。大家可能也看过，《狼图腾》的作者姜戎先生几乎是用他自己亲身的经历，以人与狼、狼与食草动物、动物与草原的故事，诉说着古老的蒙古草原生物链怎样被人的贪婪和欲望，人的愚昧和武断一节一节地破坏掉。而这，也是不可否定的现实。人类为了自己的私心，不断猎杀动物，不断毁坏生物，严重导致了生物链的毁坏。

The destruction of the biological chain is also due to human participation. Perhaps, in many people's minds, all our actions are to protect those animals. However, some inappropriate actions have the opposite effect of "more help more help". What the Americans did in the Kaiba plateau in 1907 is a good example. You may have seen that Mr. Jiang Rong, the author of wolf totem, almost uses his own experience to tell the story of man and wolf, wolf and herbivore, animal and grassland about how the ancient Mongolian grassland biological chain was destroyed by man's greed and desire, man's ignorance and arbitrariness one by one. And this is also an undeniable reality. Human beings hunt animals and destroy living things for their own selfish heart, which leads to the destruction of the biological chain.

综上所述，生物链的毁坏，是因为它的自然原因，还因为人类的任意参与。

To sum up, the destruction of the biological chain is due to its natural causes, as well as the arbitrary participation of human beings.
