Again this is not all. People have become more money minded. They are not like their fore fathers who were simple and religious. They treated God as Almighty. They feared God. But the modem man has almost forgotten those values of life. Science has changed human outlook to a great extent. He is not a carefree man like his ancestors. He leads an artificial way of life. He glorifies in outward comforts of life. Thus science has dealt a blow to the ancient values of humanity.
If the man starts thinking of the future of the human race, he must have to give. Up the path of destruction. If he works like a sane man and stops working for building up nuclear arsenals, this earth is bound to tum into a heaven, otherwise the worst type of disaster may wipe out the remains of human and other types of life on this beautiful planet. Science is a blessing in disguise, but if the scientific knowledge is misused, it makes hell of it.
