The Planet’s Response to Human Activity. Thermodynamic Approach

The applicability of the laws thermodynamics to processes on Earth is discussed and it shown that chemical provides reasonable basis for predicting probable changes. historical evolution planet considered in framework Harari approach; a civilization’s level estimated by Kardashev scale based amount energy able use. During short interval (≈500 years), when effect biological imperceptible main changes are caused human activity, two systems considered: 1) nonequilibrium inhabited 2) quasi-equilibrium hypothetical without people, which accepted as comparison system. It response impact, equilibrium system with primordial nature disturbed initiated aimed prevent further growth production. In case real planet, this implements preventing uncontrolled activities humans—the producers. Climate change, an increase number natural disasters epidemics can be recognized direct while socio-economic relations, morality, demographic situation, new threats etc. indirect reaction changing conditions beings. latter results from mutual correlation between progress society, one hand, humanitarian political processes, other. role renewable non-renewable sources taken into account.
