Isolating human activities causing pollution to specific and limited areas could help to reduce only soil pollution. However, air and water pollution can not be checked. They do not remain confined to specific areas after pollution. Air pollution for example, brings about global environmental changes such as acid rains, global warming and depletion of ozone layer.
Water is continuously moving in streams, rivers, lakes, oceans etc.and hence distributes wastes to far-off places from the point of their discharge. Pollution of underground-water will affect a large area.
Finally, you need to remember that air, water and soil are naturally inter-related resources. Pollution of any one resource will affect the other in some or the other way.
