the answer is very complex and can not be answered easy , I did some research and I found an interesting article on the subject, Ref . http://www.iwmi.cgiar.org/brightspots/PDF/Globally/Reversing_trends.pdf
Water degradation is also known as water pollution. It is the contamination of water bodies such as lakes, oceans, aquifers, rivers, and groundwater.
Degradation of water quality is the contamination of water bodies like lakes, rivers, oceans, aquifers and ground water by pollutants. Water degradation damages and harms the lives of humans, animals and plants to a great extent.
Plastic degradation is the degradation of plastic.
The products of the thermal degradation of benzoic acid are carbon dioxide and water.
This is the addition of water to a substance. The water molecules break bonds in the original substance, therefore forming simpler substances.
A thermal degradation reaction; continuing heating at at higher temperature carbon dioxide, water, nitrogen and sulfur oxides, residual ash are obtained.
Degradation of water quality is the contamination of water bodies like lakes, rivers, oceans, aquifers and ground water by pollutants. Water degradation damages and harms the lives of humans, animals and plants to a great extent.
matter degradation
This is the degradation of a substance after the reaction with water.
water corrosion
habitat degradation
water and oxygen
A degradation reaction breaks down a large molecule into smaller molecules. For example, the enzyme catalase breaks down Hydrogen Peroxide into Oxygen and Water.
Plastic degradation is the degradation of plastic.
The effects of the environmental degradation are: 1. water pollution and water scarcity 2. air pollution 3.solid and hazardous wastes 4. deforestation 5. loss of biodiversity 6. atmospheric changes
water pollution soil degradation
social degradation
A degradation reaction breaks down a large molecule into smaller molecules. For example, the enzyme catalase breaks down Hydrogen Peroxide into Oxygen and Water.
