Physical self-help, self-labor involves decentralisation of control, because of individual resistance to bureaucratic or economic decisions. The consequence is a change of the relation that the men have with the non-human nature: the use of natural forces for human ends becomes more ecological. Selflabor as physical self-help - for example in housing - produces an unintended process towards greiter control over natural phenomena for the individual by realization that men are dependent on n&n-human nature differentially.
