Scientific method of cultivation has solved the food problem. The pests destroying the crops are killed immediately by pesticides. The green revolution has produced new hybrid varieties. Poultry and sericulture are also improved.

There are some evils also. Man has achieved good progress due to Science. But the same Science can destroy mankind. Modern scientific weapons like atom bombs, hydrogen bombs can wipe out the human race. Hiroshima, Nagasaki and Vietnam stand as examples of destruction caused by the scientific inventions. We have to take steps to use Science on the right lines thus Science is a good servant if it used properly and a bad master if it is not controlled.
