Step-by-step explanation:
Today, science has so much involved in our life that it is really hard to imagine living without the science. Every part of life whether it is food or recreation is related to science and its various ways. To decide that whether science is a boon or a bane for mankind is not a simple decision.
We should first look for the exact meaning of science. A systematic classification of experiences is called as scientific. We surprise many times at various events happening around us due to technology and science. We get doubts; what are they? These concerns are the primary seed products for technology. First start from thinking, reasoning, research, features, evaluation and distinction and lastly the fact comes out.
According to Scientists, there is a scientific method for everything and there are unavoidable actions to be followed:

(5) Evidence.
All researchers have in a way followed this scientific method.
The basic aim of Science is to look for reality and to find those factors, formally uncommon. A scientist cannot accept the principles, usually because; they were accepted by others formerly. Great discoveries are always coming from reasoning. A lot of determination and observation are required. Civilization, as it is today, also came from numerous discoveries that were made in the field of Science.
Electricity is a main source of energy has revolutionized the Earth. Science has made medical field enough advanced that today the average life of a human being has raised to 90 years. Science also worked for plant life as well and now we have enough food for all.
ADVERTISEMENTS:
We have enough clothing and better security too. This all became possible due to science and technology. Computers, Cell phones, TV and Radios are all products of Science. So, it is very easy to conclude that Science is beneficial for mankind.
There is also another side of the coin. Destructive weapons like guns, rifles, atom bombs etc. are also came from Science. It is science that gave us different types of power like electric power and nuclear power. If all these powers and weapons are not used in a negative way, there is nothing to fear. But, unfortunately these all powers are destructing our Earth. Can anyone think that there are no chances of such horrible destruction of an Iraq again? If it happens, how can be science beneficial for mankind?
Man is a logical being. It is possible for everyone to save himself from the odds. Only through this way, he can win and control everyone on the globe. Only wisdom can help a man to conquer the World. Science without conscience is death of the soul.
