Reduction of pollution: Principles and guidelines

No comments :

Following principles and guidelines have been accepted for the control of different types of pollutions-

 1. Prevention of entry into the environment: According to this principle pollutants are checked at the point of their origin and are not allowed to enter into the environment by the application of specific devices.

2. Isolation: By isolation, we mean putting out or segregating pollutants at the point of their release or production. Such isolated pollutants should then be dumped at specific locations as per scientific guidelines adopted by pollution control agencies. Some of these pollutants can be recycled and reused for example reuse of fly-ash for making bricks.

3. Conversion from highly toxic to lesser harmful product: We can not stop industrial processes simply because they cause pollutions. However we can reduce the toxicity or harmfulness of pollutants by applying bio- chemical technologies. A number of catalysts are introduced to reduce the toxicity of chemical pollutants produced during industrial processes.

4. Alternatives: These are safer substances used on the place of substances that cause hazards. For example bio- pesticides like oil of Neem and extract of garlic, are better alternatives to synthetic chemical pesticides.
5. Destruction: The chemical pollutants that are proved to be toxic, and are difficult to be substituted by safer ones- need to be blocked from further release and then destroyed in a safe and prescribed scientific manner. Advanced and Environment Friendly Incineration Technology is a good option for reduction of pollution through destruction. 

6. Awareness: Matters pertaining to good citizenship, environmental consciousness and preventive methods must be explained to the common man, so that he may try to perform his duties with a high degree of civic sense. These awareness programmes can be conducted through different media like radios, TVs. seminars, demonstrations, documentary films, pamphlets, display of hoardings, banners and plays like street theatres or nukkar nataks etc.

7. Public Participation:The word ‘public participation’ means ‘sharing in common’ or ‘doing together’. In environmental context, it means, the involvement of the local public in solving their local environmental problems. It does not mean, people working under the planning and decisions of government agencies- it is rather bottom up approach. With joint efforts, people identify their problems, make plans to resolve them and then to implement them.

8. Environmental Education:  Environmental Education has been made a compulsory subject for studies at schools, colleges and other institutions. This is the most effective tool for the control of pollution and conservation of environment on grass- root level.

9. Self Restraint – A Habit: The greed of luxury and comfort initiates the production of newer and newer products. More and more products carry more and more wastes in different forms like wrapping materials, plastic carry bags, chemical preservatives (in cases of food materials) etc. When these products are used up, their wrappings and other associated and useless materials coming to the homes of consumers are thrown out carelessly. These thrown out materials create the problem of pollution. Overuse of materials that are not important for our health and development impose burden on the family budget. These are the reasons why our thinkers and philosophers preached on self restraint. Thus it is important now that conservation should be made a habit.

10. Support to Professional Conservation Groups: The state and central governments should provide subsidies for conservation of environment and pollution control works being carried out by professional groups.

11. Legislative and Tax Measures: The existing laws for pollution control should be enforced properly so as to abate pollution. Industries doing eco-friendly works like recycling of wastes, regeneration of forest and production of pollution free technologies should receive tax –concession from the government.

Any big problem cannot be solved without planning and strong efforts. The pollution of environment is certainly a big problem. So planning for its control is very necessary.

Key Words : principles, guidelines, pollution control, self restraint, planning
