Zoos are sometimes seen as necessary but poor alternative to a natural environment. Is it necessary to keep animals in zoos?
In the modern society, zoos are almost indispensable places in large cities for people to visit. In some large zoos, there are various animals from space to sea, and from primitive invertebrates to advanced and intelligent mammals. In the zoos, all animals, including those rare animals, such as panda, Africa elephant, and North-East tiger, could enjoy good care and protection away from any hurt. However, along with the stronger natural environmental protection consciousness, many people think that to put animals into small cages will change their living instincts, and therefore break the ecological balance.
