Our natural resources are known to have some specific qualities of their own. These qualities are known as natural qualities. It is due to specific natural qualities that different natural resources have been useful to us and to the whole biosphere. But now, the condition has changed considerably.
From different sources it has been confirmed that air pollution has increased in Indian cities after Deepawali festival. Delhi and many other cities of India are experiencing very heavy pollution. Particulate matter in these cities have increased up to such an extent that many persons have started suffering from breathing related problems.
After a long lock down period in India, air pollution in cities is rising up again during unlock period. The condition of Ranchi city in Jharkhand state is also progressing along the same line. As reported by different Pollution Monitoring agencies air pollution had dropped down considerably during lockdown period.
Conservation of species in their natural habitats- in areas where they occur under normal conditions is called in-situ conservation.
This type of conservation strategy protects the entire area. Such an area is protected and maintained to conserve all the known or unknown species inhabiting it.
In this type of conservation, species are not isolated or provided with health care, food, or mating facilities. Only factors detrimental to species’ existence and development are eliminated in this conservation strategy. Human interference, such as hunting, cutting down trees, collecting firewood, etc., is completely banned in such areas.
Animals are of different types and varieties. The world of animals is most amazing
A group of individuals of a particular species occupying a particular area at specific time is called as population. A species is a group of similar type of organisms that can interbreed under natural conditions. The interbreeding organisms of a species produce new organisms and finally result into the growth of population. This is true for all the life forms including human beings.
Living beings have many processes in common. Among all the common processes there is one very interesting and wonderful process…
Deforestation contributes up to 20 percent of greenhouse gas emission which is more than the combined emission by all the cars, trucks, planes, boats and, trains of the world. Deforestation threatens our climate. Besides this, it threatens the livelihoods of 1.6 billion people who depend on forests for food and economic activities. They serve as habitats to rare and so far, undiscovered species of plants and animals. They also play a key role in maintaining water cycles and preventing floods and soil erosion. Hence, forests across the world need urgent measure of protection by all possible ways, may it be through alternatives to deforestation.
Producers in running or Lotic type of ecosystem comprise species of algae, and plants that grow on embankments. Various varieties of molluscs, tadpoles, and insects are primary consumers whereas fish, crabs, and crustaceans are secondary consumers of this ecosystem. Numerous species of bacteria and few species of fungi act as decomposers in this ecosystem.
Respiration is different in aquatic and terrestrial animals. Aquatic animals repire by means of gills and skin while terrestrial animals breathe in through lungs.
Recently, it has been found that Photo Voltaic Cells cannot be popularly used for power generation on large scales. However, our scientists have discovered that the alignment of Carbon Nano Tube with the polymer composites substrate would give very high efficiency in Photo Voltaic Conversion.
