Essay on Science: Boon or Curse

We live in the age of science. Science has made life easier, longer and more comfortable. Electricity lights our homes and runs our machines. Buses, trains and aeroplanes carry us across the world. The telephone and the internet let us speak to anyone instantly. Medicines, vaccines and operations have conquered many deadly diseases. Tractors, better seeds and fertilisers have increased our food. In all these ways science is a great boon. But it has a frightening side as well. The same science has produced bombs and missiles that can destroy cities in minutes. Factories and vehicles have polluted the air and water. Machines have made many people lazy. The truth is that science is only a tool. Whether it becomes a boon or a curse depends on how human beings use it.

From the moment an alarm clock wakes us to the moment we switch off the light at night, we are surrounded by the gifts of science. Our ancestors could not have dreamt of the comforts that an ordinary person enjoys today. Yet the same science has given human beings the power to destroy themselves. Is science, then, a boon or a curse?

Let us first count the blessings. Electricity is perhaps the greatest. It gives us light, runs our fans, refrigerators and factories, and powers our trains. In transport, science has given us the bicycle, the car, the railway and the aeroplane; a journey that once took months now takes hours. In communication, the telephone, television, mobile phone and internet have brought the whole world within reach.

In medicine, science has been a true saviour. Vaccines have wiped out smallpox and brought polio under control. Antibiotics cure infections that once killed millions. X-rays and scans let doctors see inside the body, and surgeons can replace a damaged heart or kidney. The average human life is far longer than it was a century ago.

In agriculture, tractors, pumps, improved seeds and fertilisers brought the Green Revolution and saved countries like India from hunger. In education, printing, computers and online classes have spread knowledge to every corner. Science has taken human beings to the Moon and sent spacecraft to other planets.

Now look at the other side. Science has made war more terrible than ever. The atom bombs dropped on Hiroshima and Nagasaki in 1945 killed a vast number of people in moments, and today's weapons are many times more powerful. Factories, power plants and vehicles pour smoke into the air and waste into rivers, causing pollution and global warming. Plastic has littered land and sea. Machines have taken away some jobs, and the comforts of modern life have made people less active, leading to new diseases. Mobile phones and the internet, when misused, waste time and spread falsehood.

Who is to blame for these evils: science or the people who use it? A knife in the hand of a surgeon saves a life; in the hand of a criminal it takes one. The knife is the same. Science gives power, but it does not tell us what to do with that power. That choice comes from our values.

Science is a good servant but a bad master. If it is guided by wisdom, kindness and a sense of responsibility towards nature, it is the greatest boon humankind has known. Our task is to make sure that it is always used to build and never to destroy.
