We know that all species are important for maintaining ecological balance. If one is lost, the whole natural environment changes. In order to protect the environment from being spoiled, we should protect our wildlife. The good news is that many countries are now taking action to protect their endangered wildlife. George Laycock, author of several books on wildlife, writes: Mankind must develop a concern for wild creatures and a determination that the wild species will not perish. We should save the earth's wild creatures to save ourselves. To be kind to animals is to be kind to mankind.
