Even children will draw a chimney, emitting a thick column of smoke, to indicate pollution. Of course, it is not good for human beings and animals, because the carbon dust will spoil our lungs. Cement plants cause illness among the workers, for the same reason, as also, asbestos, gems etc.
The ingredients of smoke are carbon suit, carbon dioxide and fly ash. The latter will settle down in due course. CO2 will be absorbed by plants. Nothing will cause any permanent damage to the earth.
Chemicals like insecticides and dyes used in cloths making, on the other hand, cause permanent harm, as these are absorbed by the soil, thence to the plants and animals. Mercury, lead, electronic waste etc. belong to this category. During rainy season, water gets contaminated. Prevention is the only remedy available.
Water pollution can be reduced considerably by water plants, like water hyacinth, which should, under no circumstance, be destroyed. periodically, we may remove it, so that new plants would grow, absorbing more poisonous chemicals.
Plastics do not decompose for ages and should be banned strictly.
By far, the greatest lethal pollution is radiation. Nuclear power stations are the villains, masquerading as our saviors, in black suit and tie, spreading lies and half truths, because business worth billions of dollars, are like a lamb before the lion ! The responsibility for clearing the mess, is left to the babies yet to be born. There is no end to cynicism, where profit is concerned.
