I am going to put some really big problems which are need to be solved or at least noticed.
Population explosion : we dont know how we will be able to feed our next generation . could we be able to provide them a healthy environment and a good life style?
Corruption : i still can't understand that everyone i had met yet is against corruption but every government department known to me is full of corruption . does it mean we are a nation with greedy eyes or something else ?
Unemployment : youth population of india is approximately 65 crores, only four crores of them are govt. employees and 12 crores are working in private sector, what about the rest . we are a country with 50 crores unemployed youth . what can be the answer to this problem?
