面对一望无际的大海, 你一定会为它浩瀚而惊叹不已吧。广阔的海洋为人类提供了极其丰富的资源和生存空间。调查表明,海洋中的动物有10万-20万种,植物有1万多种。海洋中的植物依靠吸收海水中的养分而生长,而海洋中的动物就是靠吃这些植物而生存,动、植物死亡后又被海水中的细菌分解成为植物所需的养分,这就形成了包括植物、动物和细菌在内的海洋生态系统。这个生态系统如果没有外界杀手的破坏,就始终处于平衡的状态,即使是小环境的影响,它也能通过自身的净化而重新达到平衡。然而,近几个世纪以来,海洋生态系统的平衡已遭破坏,部分海洋已被弄得很脏很脏了。那么,究竟谁是破坏海洋生态平衡的杀手呢?
In the face of the endless sea, you will marvel at its vastness. The vast ocean provides humanity with extremely rich resources and living space. Surveys show that there are 100,000 to 200,000 species of animals in the ocean and more than 10,000 species of plants. Plants in the oceans rely on the absorption of nutrients in seawater to grow, and the animals in the oceans survive by eating these plants. After the animals die, the plants in the sea are decomposed into the nutrients needed by the plants, Plants, animals and bacteria in the marine ecosystem. This ecosystem, if left untouched by outside killers, is always in a state of balance, and even with the effects of a small environment, it can regain its balance through its own purification. However, the balance of marine ecosystems has been destroyed in recent centuries, and some of the oceans have been rendered dirty and dirty. So who is the killer that undermines the marine ecological balance?
