Environmental pollution occurred when the number of vehicles and factories increased.
To prevent environmental pollution we must see that factories use filters while excelling the air in the sky or else it may lead to acid rain.There must be containers so that metal wastes from factories can be reused and not dumped into water.Vehicles must have to do their pollution check maximum times a year and we must use public transport like buses because 40 people can travel in a bus it will cause pollution but think how much pollution will be caused when 40 people drive their own car.
thank you.
