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?

We have studied that many human activities lead to increase 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. However, air and water polluting cannot be checked. For instance air pollution brings about global environment changes such as (i) acid rainfalls, (ii) global warming due to increase in the concentration of green house gases (carbon dioxide, methane and chlorofluorocarbons) in the atmosphere, (iii depletion of ozone layer.
In the same way water moving in streams, rivers and oceans. It distributes wastes to far off places from the point of their discharge. Similarly, underground water pollution due to sewage, industrial wastes and agricultural percolatioin (of fertilizers and pesticides) will affect large areas.
