Focus the assessment activities on gathering evidence in terms of the main outcome expressed in the title to ensure assessment is integrated rather than fragmented. Remember we want to declare the person competent in terms of the title. Where assessment at title level is unmanageable, then focus assessment around each specific outcome, or groups of specific outcomes. Make sure evidence is gathered across the entire range, wherever it applies.
February 5, By Ankita Mitra Environmental pollution refers to the introduction of harmful pollutants into the environment. These pollutants contaminates the environment. It has a hazardous effect on the natural world and on the activities of living beings. The major types of environmental pollution are air pollutionwater pollution, noise pollutionthermal pollutionsoil pollution and light pollution.
Please read the article on different types of pollution to know more about it. Deforestation and hazardous gaseous emissions also leads to environmental pollution. During the last 10 years, the world has witnessed severe rise in environmental pollution. Without air and water the earth would be like the other planets — no man, no animals, no plants.
The biosphere in which living beings have their sustenance has oxygen, nitrogen, carbon dioxide, argon and water vapor.
All these are well-balanced to ensure and help a healthy growth of life in the animal world. This balance does not only help the life-cycles of animals and plants, but it also creates the perennial sources of minerals and energies without which the human civilization of to-day could not be built.
It is for this balance that the human life and other forms of existence have flourished on earth for so many thousands of years. Nor were they content with the bounties of nature.
The quest of human-beings for knowledge and search for security succeeded in exploring newer and wider avenues of mysteries that remained baffling so long.
The conquests of human-beings had ensured their domination in their world and gave them a key to control all the forces in nature. The surge in pollution is often attributed to the wide scale urbanization and large-scale industrialization, which is in turn a product of our advancement in science and technology.
And, it is here that man first began losing control and became victim of his own creations. Sources and Causes The sources and causes of environmental pollution includes the following: The industries all over the world that brought prosperity and affluence, made inroads in the biosphere and disturbed the ecological balances.
The pall of smoke, the swirling gases, industrial effluents and the fall-out of scientific experiments became constant health hazards, polluting and contaminating both air and water.
Chemical waste resulting from industry can pollute lakes, rivers and seas and soil too as well as releasing fumes. Household and commercial waste pollutes the environment when not disposed of properly.
The smoke emitted by vehicles using petrol and diesel and the cooking coal also pollutes the environment. The multiplication of vehicles, emitting black smoke that, being free and unfettered, spreads out and mixes with the air we breathe.In all of the tables in this document, both the pre NQF Level and the NQF Level is shown.
