Nothing can be of benefit unless it is used and applied in a controlled manner. Salt is very beneficial for us, but when this salt is used too much, this causes high blood pressure. Similarly, science has to be controlled..The continuous inventions of science is definitely good for us, but not always.
Y do we guys need to control science?? Can't we see it's positive side... Agree it does have some negatives too but that's the case for each and everything in this world... But the point is the negatives can be sorted out by your positive attitude.
SO FRIENDS IT IS NO CHALLENGE!!!!
