Science has made great progress in recent times. Through science man has been able to conquer nature. He has acquired control over land, air and water. Time and distance have no meaning in this sputnik Age. Some people think that science is responsible for wars. It has placed in the hands of the man extremely destructive weapons. They may ruin the world completely. It may be true to some extent. But science has also contributed a lot towards world peace. Today very fast means of transport and communications are available. Armies can be moved from one place to another in no times.
These forces check the advance of an enemy. Thus war is prevented. Big wars break out due to certain causes. Poverty, disease, hunger, etc. , are enemies of mankind. Some countries are rich while others are poor. Scientific inventions have given us valuable machines. With their help production has been increased manifold. Even the backward and poor countries have now begun to enjoy a better standard of living. The contribution of science to medical science is well known to everyone. Wonderful drops like penicillin, streptomycin, Chloromycetin, etc. , have been discovered.
They have ensured long and healthy life to the people of the world. By removing such causes of war, science has helped in reducing the chances of a world war to the minimum. Small sparks lead to big conflagrations. Similarly minor internal disturbances within a country sometimes lead to big wars, but now-a-days the police and military can be sent to the spots of trouble within no time. Thus, internal peace is far more secure today than it ever was. Science has given very effective means of propaganda. The Radio, the Television, the News paper and the cinema are very powerful means of propaganda.
Through them, the people of the world can easily know the horrible effects of modern warfare. Through cinema, pictures of horrors of war are shown to the people. Thus public opinion is created against war. This also helps in preventing war. Science has not reached the limits of its inventions even now. It is making even more starting inventions. It is now busy in acquiring control over outer space. Furthermore, man is today more conscious of necessity of world peace than ever before. He has begun to use his knowledge of science for peaceful purposes. Let us be optimistic that science enables us to banish war completely in the near future.
