__ Forms of Ecological Crises in India:
There can be different forms of Ecological Crises, differ according to the situational differences. Some forms found in Indian situation are:
2.1. Pollution: pollution refers to any drastically changes in the natural qualities of ecosystem brought by chemical, physical and biological factors. There can be four types of pollution. Such as:
2.1.1. Water Pollution: water pollution is one of the urgent crisis being faced by both the developed and developing world together. Water of rivers, lakes, wells, streams and Oceans are polluted by natural and human waste of households, factories and industries, etc.
2.1.2. Air Pollution: The air can also be polluted and is being polluted by foreign elements or gases or other ingredients which are emitted from industries, motor vehicles and human made materials.[4] When air contains such unusual gases, the atmosphere becomes polluted and it damages biodiversity of the air or atmosphere.
2.1.3. Noise Pollution: Noise pollution is sounds without harmony and which does not have no meaning to the listeners. Those wrong or unwanted sounds are produced by human voices, musical instruments, motor vehicles, factories, etc.
2.1.4. Radiation Pollution (nuclear pollution): Radiation itself is not bad at all, but when the contents reach beyond the level, it becomes dangerous. Radiation pollution is the degradation of environment due to the release of radio-activities by the sun, nuclear powers and various electronics and scientific devices.
2.2. Ozone layer Depletion: Ozone layer is known as the umbrella of the Earth. It protects the Earth from direct ultra-violet radiation (UV rays) from the sun which could damage all living creatures on Earth. Ozone is present at all attitudes mainly in the stratosphere (12kms – 35kms).[5] And this became one of the subjects in ecological crises because of its depletion. Ozone layer of its molecules is depleted by chlorofluoro carbons (CFC) emitted from science and technological developments of the worldAn ecological crisis occurs when the environment of a species or a population changes in a way that it destabilizes its continued survival.
