1.) Explain the function of the environment.
Ans – The environment performs four vital functions (I) it supplies resources: resources here include both renewable and non-renewable resources.Renewable resources are those which can be used without the possibility ofthe resource becoming depleted or exhausted. That is, a continuous supply of the resource remains available. Examples of renewable resources are the trees in the forests and the fishes in the ocean. Non-renewable resources, on the other hand, are those which get exhausted with extraction and use, for example, fossil fuel. (ii) it assimilates waste (iii) it sustains life by providing genetic and bio diversity and(iv) it also provides aesthetic services like scenery etc.
2.) What is the reason of environmental crisis?
Ans -The environment is able to perform these functions without any interruption as long as the demand on these functions is within it carrying capacity. This implies that the resource extraction is not above the rate of regeneration of the resource and the wastes generated are within the assimilating capacity of the environment. When this is not so, the environment fails to perform its third and vital function of life sustenance and this results in an environmental crisis.
3.) Explain the factories which are responsible for land degradation.
Ans -Following factors are responsible for land degradation are (I) loss of vegetation occurring due to deforestation (ii) unsustainable fuel wood and fodder extraction (iii) shifting cultivation (iv) encroachment into forest lands (v) forest fires and over grazing (vi) non-adoption of adequate soil conservation measures (vii) improper crop rotation (viii) indiscriminate use ofago-chemicals such as fertilisers and pesticides (ix) improper planning and management of irrigation systems(x) extraction of ground water in the competing uses of land for forestry, agriculture, pastures, human settlements and industries exert an enormous pressure on the country’s finite land resources.
4.) What things are needed to achieve sustainable development as per Herman Daly.
Ans -According to Herman Daly, a leading environmental economist, to achieve sustainable development, the following needs to be done (I) limiting the human population to a level within the carrying capacity of the environment. The carrying capacity of the environment is like a ‘plimsoll line’ of the ship which is its loadlimit mark. In the absence of the plimsollline for the economy, human scale grows beyond the carrying capacity of the earth and deviates from sustainable development (ii) technological progress should be input efficient and not input consuming (iii) renewable resources should be extracted on a sustainable basis,that is, rate of extraction should not exceedrate of regeneration (iv) for non-renewable resources rate of depletion should not exceed the rate of creation of renewable substitutes and (v) inefficiencies arising from pollution should be corrected. In 2015, the UN formulated 17 Sustainable Development Goals (SDGs) intended to be achieved by the year 2030. Collect the details of those goals and discuss them in the context of India.
5.) Explain the use of solar power by Indian.
Ans -India is naturally endowed with a large quantity of solar energy in the form of sunlight. We use it in different ways. For example, we dry our clothes,grains, other agricultural products as well as various items made for daily use.We also use sunlight to warm ourselves in winter. Plants use solar energy to perform photosynthesis. Now, with the help of photovoltaic cells, solar energy can be converted into electricity. These cells use special kind of materials to capture solar energy and then convert the energy into electricity. This technology is extremely useful for remote areas and for places where supply of power through grid or power lines is either not possible or proves very costly.This technique is also totally free from pollution. In recent years India is taking efforts to increase the power generation through solar. India is also leading an international body called International Solar Alliance (ISA).
