Environmental ManagementLearning Outcomes: 1. Evaluate environmental management and management systemsExamine the International environmental concerns such as Greenhouse effect, Ozone depletion and many othersIdentify and analyse the relevant regulatory frameworks4. Assess the new technologies and approaches to environmental managementENVIRONMENTAL CHALLENGESThe earth is the only living and breathing planet in our solar system. The life of fauna and flora as well the future of the human race would depend upon its health. However, rapid advancements in sciences, industry and nuclear armaments have led to considerable changes in the environment of this beautiful planet. There are many contributing factors that lead to ecological imbalances and environmental degradation.
The major causes have been appended as follows: (A) Depletion of Forests There is a reduction in annual rainfall in those areas where forest covers have been depleted. Imbalance of proper supply of oxygen adversely affected all the living organisms. Air pollution has increased. Forest covers minimise soil erosion during floods and are also, a natural habitat for wild life. With the reduction in their size, the fertile land as well as wild life has been seriously affected. Abu Dhabi Civil Defence to reduce pollution within Abu Dhabi and the other Emirates, they have to look on this matter with care. (B) Ozone layerOzone layer surrounds the atmosphere of the earth and protects us from harmful solar radiations.
It also protects the earth from over- heating. However, Chloro Flouro Carbons (CFCs), Carbon Monoxide and other gases rise up in the atmosphere and form compounds with Ozone gas. Thus density of Ozone gas is reduced above the surface of the earth in the upper atmosphere. This phenomenon is termed as Ozone Hole.
This hole allows the harmful ultraviolet rays to pierce through the atmosphere and fall on to the surface of the earth. The earth gets heated up and the living beings are also exposed to these rays. If these unhealthy trends continued, then polar ice caps would melt which would eventually raise the ocean levels. (C)FloodsDue to melting of the polar ice caps, the ocean levels would rise. So, low levels areas of the earth would be submerged. There would be small land left for us. For example, low lying areas would be submerged first due to the melting of polar ice caps. (D) EarthquakesIf the poles of the earth get heated up due to Ozone holes, the ice would melt and would flow into the oceans.
This would result in dangerous imbalances. So, the axis of the earth would shift. This could result in earthquakes. This natural disaster has already affected many nations; India, Iran, Mexico, the USA and China are examples; Abu Dhabi Civil Defence to reduce pollution within Abu Dhabi and the other Emirates, they have to look on this matter with care. (E) Man-made CausesMan is causing environmental degradation through pollution.
He is polluting the mother earth by three methods. Firstly, man is polluting the air by burning millions of tones of hydrocarbon fuels. The poisonous gases coming out of the vehicles, plants and factories, generators etc are making life a misery for our children. Delhi is as the fourth largest polluted city in the world. Environmental pollution has brought diseases like TB, lung cancer, eye defects, Asthma, infections, bronchitis etc for adults and childrenalike.
