We want to protect wild animals,because we protect wild animals,wild animals on our human will be very friendly.
For example,swallows,swallows can help us to eat the pests of the field.If we kill people to capture them,they will eat those who often come to harass our mosquitoes,let us live better? No swallow,we become a lot of pests around,these pests on our human great harm it!
I also give an example.For example,frogs,frogs can also help us to eat the pests of the field,can be said that the field of the police.We kill them,once there is no frog,the field of pests more and more pests continue to eat,do we have a good harvest it?
I also give an example.For example,woodpecker,woodpecker is a doctor in the forest,it can help us eat the pests in the tree,so that the tree back to health.We kill them,trees will be more and more pests,trees will slowly reduce.There is no tree on earth,will flood,earthquake.
I finally give an example.For example,owls,owls catch voles,is good for our human beings,but humans often hunt them.No owl,the vole will increase.The voles eat more crops and vegetables,and we do not have a good harvest.
So we have to protect the animals above.At the same time,we have to protect other wild animals!
