科学课上,科学老师告诉了我们,我们不可以去任意的猎捕生物,因为每一个生物都和许许多多的生物有关。以前有一个国家猎捕狼,之后,狼所剩无几了但是情况没有好转,因为牛羊大批大批的繁衍,结果草原的草不够了,变成了另一种灾难。
In the science class, the science teacher told us that we can't hunt animals at will, because every creature is related to many creatures. There used to be a country that hunted wolves. After that, there were few wolves left, but the situation did not get better. Because of the large-scale reproduction of cattle and sheep, there was not enough grass on the grassland, which became another disaster.
如果把蚊子、苍蝇……那一些害虫消灭了,反而还会危及到益虫,为什么叫益虫呢?大多是因为他可以消灭害虫,如果害虫被消灭光了,那么益虫都会被饿死,也有可能因为食物的关系,变成更强大的害虫,这也不是没有可能,熊猫以前不是吃肉的吗?为什么现在改成吃素的了,这都是因为生物链被别人破坏了。
If mosquitoes, flies When some pests are eliminated, they will endanger beneficial insects. Why is it called beneficial insects? Most of it is because it can kill pests. If the pests are wiped out, all the beneficial insects will starve to death. It is also possible that they will become more powerful pests because of the food. Isn't it impossible that pandas used to eat meat? Why is it now vegetarian? It's because the biological chain has been destroyed by others.
