为什么要保护鲨鱼？

鲨鱼是海洋生态系统中的重要一环，对于维持海洋生态平衡起着至关重要的作用。然而，由于各种原因，鲨鱼种群正面临严重的威胁，因此保护鲨鱼显得尤为重要。以下就是我们需要保护鲨鱼的原因：

1. 生态平衡：鲨鱼作为海洋食物链的顶端掠食者之一，对于维持海洋生态平衡起着关键作用。当鲨鱼数量过多时，它们会捕食过多的猎物，导致海洋中的其他生物数量减少。当鲨鱼数量减少时，海洋中的其他生物数量可能会增加，这可能会导致整个海洋生态系统的失衡。英文翻译：

Why do we need to protect sharks?

Sharks are an important link in the marine ecosystem and play a crucial role in maintaining marine ecological balance. However, due to various reasons, shark populations are facing serious threats, making it particularly important to protect sharks. Here are the reasons why we need to protect sharks:

1. Ecological balance: As one of the top predators in the marine food chain, sharks play a crucial role in maintaining marine ecological balance. When there are too many sharks, they may over-consume their prey, leading to a decrease in other marine biota. When the number of sharks decreases, the population of other marine biota may increase, which may lead to imbalance in the entire marine ecosystem.
