Science has given us pleasures and comfort in many fields . It has improved our transport facilities and also improved our strength to fight many diseases and much more . It's good to have a good technology and hi~tech life it is also to be kept in mind that at the same time this science , this technology can be the worst too. It's ok you use appliances like cell phones , but to a limit , excess use of it will make u a servant of cell phone and u will make cell phones ur master.This should not be done . Daily news is coming the phone blasted on the ear only , phone blasted due to excess use , phone blasted due to excess charging .....etc. I think these are some sufficient examples to make u aware of the consequences . The master or u can say that inventor of Nuclear weapons is the human but can human control the disasters caused by nuclear bombing ?? Say ?? Now guess who is the real master now ? Absolutely the SCIENCE ., the unwanted technology .However, Science cannot be blamed for its abusive uses. Man is responsible for the abuses of science. It fully depends on us whether we shall have our science to destroy the creation or to conquer hunger, poverty and disease for a happy and prosperous world.
