In addition to food, people in need of protective device to prevent its overheating pereohlazhdeniyuili in places that are not optimal from the perspective of human biology. Finally, the man he needs to travel for pleasure, not only for all kinds of mechanical work aimed at increasing the proportion of edible substances. Man has long been living in the noosphere, the idea of ??which formulated the remarkable Soviet scientist Vernadsky. If we calculate what amounts of energy (through its equivalent - heat) produced by man, it is clear that the thermal products consumed by one person for a long time beyond all possibility of developing such a product by the human energomashinoy (heat production of human energomashiny a rough estimate all the energy directly use a person for the construction of the body and mechanical work). And when you consider that most of the energy is spent, not in order to move the man and the creation of an artificial living environment and production of devices for protection from the cold and to produce more edible substances, it becomes clear that people have long been living in debt from nature.
