Think Ecologically ... Reduce. Reuse. Recycle.

Pollution Control
           
            Pollution control is a term used in environment management. It means the control of emissions and effluents into air, water or soil. Without pollution control, the waste products from consumption, heating, agriculture, mining, manufacturing, transportation and other human activities, whether they accumulate or disperse, will degrade the environment. In the hierarchy of controls, pollution prevention and waste minization are more desirable than pollution control. In the field of  land development, low impact development is a similar technique for the prevention of  urban runoff.

water pollution

           
            Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans and  groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds.

            Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communties.
