[D] All of the above
Show Answer
Correct Answer: D [All of the above ]
Notes:
Checking atomic blasts will reduce radioactive pollution. Sewage pollution can be prevented by treating sewage before passing into water course, in sewage treatment plant or effluent treatment plant (ETP). Electrically operated vehicles will control automobile exhaust and improve the air quality in cities. Environmental pollution can be controlled by treating factory wastes before disposing of them. So, if we treat wastewater before disposing of in a river, it will surely decrease the amount of dumped pollutants. For example- Steel industries have a high concentration of cyanide in it, and it led to harmful effect. So, treatment is really necessary.
