Mankind can product the energy not only from oil. There are wind energy, sun energy. Soon people will switch to this types of energy product.

Transaction can be done everywhere and everytime. Bitcoin helps with the prevention of poverty which will helps rather than destroy world. Energy sources must be nature friendly which will prevent the concern of world distruction.
