In some respects, animals are superior to men. Much of the animal is still in us. Buddhists are encouraged to love all living beings and not to restrict their love only to human beings. They should practise loving kindness towards every living being. The Buddha ' s advice is that is not right for us to take away the life of any living being since every living being has a right to exist.
Animals also have fear and pain as do human beings.
It is wrong to take away their lives. We should not misuse our intelligence and strength to destroy animals even though they may sometimes be a nuisance to us. Animals need our sympathy. Destroying them is not the only method to get rid of them. Every living being is contributing something to maintain this world.
