We know that many human activities lead to increasing levels of pollution of the air, water-bodies and soil. Do you think that isolating these activities to specific and limited areas would help in reducing pollution?

Explanation

You have studied that many human activities lead to increases the levels of pollution of the air, water-bodies and soil, Isolating such activities to specific and limited areas may help in reducing only soil pollution. Howerver, changes such as : (i) Global warming due to increase in the concentration of green-house gases (carbon dioxide, methane, chlorofluorocarbons etc.)
(ii) Depletion of ozone layer.
In the saem way, water keeps of moving in strems, rivers and distributes wastes to far off places from the points of their dischrge. Similarly, undergroud water pollution due to sewage adn industrial wates will affect large areas.
