单选题 Don"t you find fewer and fewer animals can be seen in nature? How to protect the endangered
animals is a great problem for us all. I think that the best way to do this is to build more national
wild animal parks.
Firstly, national parks protect the animals" natural home. The forests that farmers clear for
new fields and the trees that are cut down to be used for buildings are just animals" home. If their
home is destroyed, many animals are unable to live any longer. And more of them will disappear.
Secondly, national parks protect animals from the danger of being hunted. A main reason why
many kinds are endangered is that hunters kill them for their skins, horns and so on.
On the other hand, some people are against building national parks. They consider that the
national parks will interfere with (妨碍) animals. They say wild animals are happier in the wild, though they meet some dangers.
All in all, the disadvantages are far less important than the advantages of the national parks.
These parks allow animals to live in safety in their natural environment by protecting from their greatest enemy—humans.
