Answer 26.
It refers to the development strategy to interruption till the resource extraction was not above the rate of regeneration of the resource and the wastes generated were within the assimilating capacity of the environment But today, environment fails to perform its third and vital function of the substance resulting in an environmental crisis. The rising population of the developing countries and the affluent consumption and production standards of the developed world have placed huge stress on the environment in terms of its first two functions.
Strategies for sustainable Development.
1. Use of a non-conventional source of energy: – India heavily, depends on the hydropower plants to meet its power needs. Both of these have adverse environmental impacts. Thermal power plants emit large quantities of carbon dioxide, which is a greenhouse gas. It is not used properly.
2. Bio-Composting:-Inorder to increase production, we have started using chemical fertilisers which are adversely affecting the waterbodies, groundwater system, etc. But again farmers in large numbers have started using organic fertilisers for production.
3. Mini-Hydel Plants:- Mountainous region have streams everywhere, Most of such streams are perennial. Mini-hydel plants use the energy of such streams to move small turbines which generates electricity. Such power plants are more or less environment friendly.
4. Traditional Knowledge and Practices:- Traditionally, Indian people have close to their environment. If we look back at our agriculture system, healthcare system, housing, transport, etc we find that all practices have been environment-friendly.
5. Biopest Control:-With the advent of Green Revolution, the country entered into the use of chemical pesticides to produce more which laid the adverse impacts on soil, water bodies, milk, meat, and fishes. To meet this challenge, better methods of pest control should be brought. One step is pesticides based on plants like neem. Even many animals also help in controlling pests like snakes, peacocks, etc.
6. CNG in Urban Areas:- In Delhi, the use of Compressed Natural Gas as fuel in the public transport system has significantly lowered air pollution and the air has become cleaner in the last few years.
