Dig you a well, bring you up a child and plant you a tree! (This is an old Arab proverb). Planting a tree! Only a tree at least! With the global pollution everyone must do something! The most meaningful pollution factors are: a) the thermo-nuclear tests; b) the industrial pollution; c) the automotive pollution.
About the automotive pollutions: vibrations, noises and emissions (CO2, etc…). Some contributions concerning the diminishing pollution of Otto-engines can be followed in the authors’ research (papers references): Otto Engines research, Power train research, Cam Gear (Cam Shaft) research, Drive train research, Engineering Research, Dynamics Research.
