Essay Causes Environmental Degradation
Water can also be polluted by agriculture or households cause damage to human health or the environment. This water pollution adversely impacts the health and quality of soils and vegetation (Carter, 1985).Pollutants in water include a wide range of chemicals, pathogens, and physical chemistry or sensory changes.It is found that CO2 is a good transmitter of sunlight, but it also partially restricts infrared radiation going back from the earth into space, which produces the greenhouse effect that prevents a drastic cooling of the Earth during the night.Increasing the amount of CO2 in the atmosphere strengthens this effect and is expected to result in a warming of the Earth's surface. Sulphur di oxide is considered as most harmful pollutant (Rao, 1989).
Recently, modern pollutants have emerged which are associated with traffic congestion and the use of modern chemicals in the home, in food, for water treatment and for pest control.
Before raw sewage can be carefully released back into the environment, it must be treated properly in a water treatment plant.
In a water treatment plant, sewage goes through a number of chambers and chemical processes to reduce the amount and toxicity of the waste.
Air Pollution has emerged as growing global issue among environmentalists and researchers especially in developed countries since the decade of 1960 (Kan, 2009).
It affects human and animal lives, natural ecosystems and the man-made environment.
