Water Pollution
Outline
What is water pollution?
The act of introducing contaminate into source
of water -Turn water into dangerous
and unsafe for neither direct
nor indirect consumption
Causes
Extensive Tillage (Clive A. Edwards et. al.,1990)
Silage effluent (Clive A. Edwards et. al.,1990)
Fertilizers (Deshmukh, S.N., 2010)
Pesticides & herbicides (Clive A. Edwards et. al.,1990)
Decomposition of organic waste (D. Zitzelsberger et. al.,1997)
- Silage effluent (Clive A. Edwards et. al.,1990)
- Livestock EffluentChemical waste (Bjorn Lomborg et.
al., 1978)
Silage effluent
Soil Erosion
Effects
contamination of water sources (Clive A. Edwards et. al.,1990)
- drinking water -daily uses -food crop Eutrophication (TP Kulikova et.
al., 2004)
Poisoning of aquatic life (Clive A. Edwards et. al.,1990)
Effect the agriculture activity
(V. Ratna Reddy et. Al., 2005; Bhagirath Behera et. Al., 2005)
Death of Aquatic Life by water pollution
Eutrophication
Recommendations
Law ( LM Wenner et. al., 1972)
universal filtration (sayali joshi et. al., 2008; sandeep joshi et. al., 2008)
bio-pesticides (Clive A. Edwards et. al., 1990)
bio-fertilizers (Clive A. Edwards et. al., 1990)
cover cropping (TJ Logan et. al., 1993)
Conclusion
Water pollution is a growing concern in society today. As water is a vital resource to sustain humanity, it needs to be conserved. Agricultural practices that cause water pollution should be reduced or eliminated and other alternatives should be utilized in order to combat this growing problem in society today. It is the eleventh hour and we need to take action before it is too late.
