Compliment and complain at

Wednesday, September 7, 2011


Today, the mankind is living under the shadow of sudden death. It appears that we have come to the end of our journey. Now we stand on the brink of complete and final destruction. The earth has become a dangerous place. It may explode to pieces at any moment. Man has been living on this earth for thousands of years. It has been giving him everything he needed. Then, why it has become so dangerous. The only thing responsible for this is science and its inventions. Science has brought more fear and danger than hope and comfort. In the beginning, it appeared to be the greatest friend and helper of man. It promised to overcome disease and death.
The atom bomb wiped out Hiroshima and Nagasaki. It has broken up the established institutions. What has to accomplish it has not ended poverty. He loved his neighbors’ and respected his elders. It promised to make this earth a paradise, and man an immortal god. Science has developed such terrible weapons of war that in the next world war not a single man will escape death. It has made this earth a hell and man an insane devil. Of curse, there were wars and famines sometimes. Science has, no doubt, made it possible to produce things in great quantities. The last two World Wars killed millions of people and destroyed many cities.
There are a number of scientific discoveries that have dangerous consequences. One of the best examples for a dangerous scientific discovery is the atom bomb. Millions of people were killed in the world’s first atom bomb attack on two Japanese cities. Even after the years of that incidence, many people are still suffering from the dangerous effects of atomic radiation in those cities. Nowadays many countries possess the atomic weapons. Some countries also possess dangerous chemical and biological weapons that can cause mass destruction. What would be the consequence of using those weapons of mass destruction? Have we really created a safe world for our children or grand children? There are many questions still need to be answered.

Many people do not know the dangerous effects of global warming. Our earth has a protective cover known as the Ozone layer, which prevents the harmful ultra violet radiation from the sun. Due to the high consumption of petroleum products, a lot of waste products are released in the atmosphere. This will result in global warming. Even our air conditioner machines and refrigerators release some gases which might cause holes in the ozone layer. The direct effect of global warming is climate change and the indirect effect is sea level rise due to the melting of ice in the Antarctic region. Therefore the results of global warming can be dangerous to our future generation.
I accept that we enjoy a number of benefits due to scientific discoveries. Though we enjoy a number of benefits we still have to consider the long term effects of scientific inventions. In my opinion, most of the scientific inventions are dangerous to human society in the long term. We need electricity to enjoy a number of scientific inventions. For producing electricity, we have to depend on natural resources so we are excessively utilizing those resources without thinking about our future generations. The same is the case in other scientific inventions also. Therefore, I would like to emphasize that the scientific inventions should be used only for the benefit of our society.
