Science has changed the world we live in. The science is both a boon as well as a bane to humankind.
Science, a boon:
Technology is very useful to us. Its discoveries and inventions make our life comfortable in many ways. They have given us better and quicker means of transport and communications. Trains, Buses, Cars, Aeroplanes, Ships, Electric Trams,and Auto-rickshaws help us to move from one place to another very quickly. The Radio and TV are wonderful sources of amusement and knowledge.
Medical Science removes our diseases. It increases our longevity. Science gives us factories and industries which give jobs to thousands of people. Electricity and electrical appliances give us light, energy and help in working machines.
Science, a bane:
The following are some of the evils that the world battles due to the immense growth of technology.
- Changing Trends in Internet Usage:
Cyber-attacks are growing in a disturbing number; itis predicted that the situation will only get worse and continue to spike just like it has over the past few years. The cyber-attacks originated from various countries around the world such as the US, Pakistan, Brazil, Bangladesh, United Arab Emirates, Europe and China amongst others. Hackers always use special masquerading techniques and hidden servers to stay out of trouble.
- Energy Crisis:
Our energy resources such as petroleum, biofuel, coal,etc., are mostly non-renewable sources. The energy crises due to the excess usage of these resources are not only depleting the sources fast but are also adding to the greenhouse gases which are in turn adding to the global warming conditions.
- Ozone layer depletion:
Ozone, a protective layer is what saves the earth from harmful ultra-violet rays of the sun. But due to theemission of CFC gases, the ozone layer is getting depleted. If the emission of these gases and other harmful gases are not checked, the ozone layer will disappear very soon. This may expose the living beings to harmful radiations which cause the life-threatening diseases like cancer.
The fast pace of growth and expansion in the name of development without comprehensive understanding or preparedness has brought forth a range of issues that seek urgent attention at all levels. In the absence of such measures growing numbers in the population are at risk of prospective hazards such as air accidents, mine flooding,etc., Creation of specific infrastructure is imperative to avoid a catastrophe in the future.
