Disadvantages of Science
As the saying goes ‘there is no rainbow without rain’, similarly science has drawbacks of its own. One must always remember that anything in excess is poison, and science is no different. If it falls into evil hands, it can cause destruction on a massive level. For instance, science is used to create nuclear weapons.
These are deadly enough to cause war and wipe out full-fledged countries. Another drawback is the pollution caused by it. As the world became more industrialized because of science, pollution levels increased. All the high-scale industries are now polluting natural resources like water, air, wood, and more.
Subsequently, this industrial growth has increased rates of unemployment as machines are replacing human labor. So, we see how it also has a considerable amount of drawbacks as well.
In conclusion, we can say that surely science is very beneficial to the modern man. But, innovations and discoveries have also become destructive in various ways for mankind.
Conclusion
Therefore, it must be properly used for the greater benefit of mankind. We must ensure the wise use of these scientific inventions in order to save the world from the evil side of science. As Dr. A.P.J. Abdul Kalam once stated that science is a beautiful gift to humanity, we must not distort it, likewise, we must live by this quote and monitor the utilization.
