What we have currently and what we are going to face in future? We all know that somehow science is going to depth of innovation, but still we are using fossil fuels or we can say Non- renewable energy sources like petroleum. We are using processed petroleum in daily uses, in industry, for transportation. But now we have enough Non-refundable energy sources on the earth. According to environmental experts we have only 9% of total Non-refundable energy sources that will last long till more than 20 years. To be honest our grandchildren will not be able to use any Non-refundable energy sources if we spend and vest most of it. And that might become one of the ancient things that appeared in the past.
Whosoever following us, if he be worthy, shall become one of us
