All the above wonders have been possible only due to development of science and technology.
But science and technology has also been abused by many people. The gross use of science and technology for destructive purposes has twined it to a curse. Deadly scientific weapons like atom and hydrogen bombs, missiles can destroy the whole world in a moment.
Atomic energy can be used effectively for constructive purposes. It can turn a desert into a fertile land. It can also be used in curing some incurable diseases, if scientific research is properly made in this respect.
Thus, science and technology can make the human civilization perfect in all respect.
