Can Animals Be Made to Work for Us?

Can animals be made to work for us? Some scientists think that one day animals may be taught to do a number or simple jobs. They say that in a film or on TV, we may see elephants or monkeys, dogs, bears or other animals doing a lot of things. If you watch carefully, you may find that those animals are always given something to eat in return for doing them. The scientists said that many different animals may be taught to do a number of simple jobs if they know they will get something to eat in return. Of course, as we know, dogs can be used¹ to guard² a house. And elephants can be used to do some heavy jobs. And we can also teach animals to work in factories. Apes³, for example, have been used in America to help make cars. And scientists believe that these large monkeys may one day get in crops⁴ and even drive trains.
