essay on nature conservation
Answers
As a student, what have you done to protect our environment? Do you know why we need to conserve our wildlife? We must make a conscious effort to conserve the world's plants and animals. Plants are essential for our own survival. Plants use the sun's energy to make food—a process called photosynthesis.
Therefore plants are the first important link in the food chain of which humans also form a part. During photosynthesis, oxygen is released and oxygen is vital for the existence of life itself.
Animals need plants in order to survive, but plants also need animals. Animals and plants are therefore delicately bound together. The removal of even one species of animal/plant can drastically alter the ecosystem. Isn't this frightening?
Our own survival may be threatened if we cause too much disruption to the natural processes that occur on this Earth. Destruction of rain forests, for example, has reduced the local rainfall. A further reduction in rainfall will increase desert areas.
We need to preserve our wildlife as well. We use many plants and animals to supply us with food, materials, chemicals, etc. If we continue to exploit these species to a point where they cannot replenish themselves, they will no longer be available to us.
Gradually if we manage to destroy most of the world's animals and plants, the Earth will become barren. For a moment, let us stop being selfish. Do we have the right to destroy animals and plants which have as much right as us, humans, to share this planet?
All life on Earth, be it humans, animals or plants, is the product of millions of years of evolution. This tiny planet is the only one we know of on which life exists. Therefore, we need to learn to co-exist with the species which have evolved with us, and take active steps to ensure their survival.
Some of the resources we have got from nature are called Natural resources. Air, sunshine, water, land, animal, vegetation, soil, metals, petroleum and minerals are the examples of natural resources.These resources are essential for the survival on this earth with no production and some are with no limitations like sunshine, air, land, soil and water.Human cannot produce or make natural resources but can use it in such manner to produce other essential resources that are important for our life. Wood obtained from trees can be used for making important things for life like house furniture and paper. Oil is refined, so that can be used for cooking food. Minerals and metals are used for making usable things for our daily life like coins, steel and jewellery, land soil and water are used for plantation of trees and with the use of plants and trees we get vegetables and fruits; sunshine is used for producing solar energy.Natural resources are of two types one that can be regained or reproduced is called Renewal Resources and other that cannot be regained is called Non renewal Resources. Wood, vegetation, animal, water, air and sunlight are the example of Renewal resources. Some of these are reproduce with low rate or low frequency and higher consumption rate of them may be the cause of non availability of natural resources in future like water, fresh air, plants and animal. Coal, minerals, metals and petroleum are counted in list of non-renewal resources which are limited in quality and hidden under the land of this earth.Using and consuming natural resources should be managed in such manner that rate of production would always more than rate of consumption especially in matter of plants, animals, fresh air and water. Non-renewal resources are very limited in quantity and cannot be recollected from nature at any cost. Even renewal resources should also be consumed with extra care by keeping in mind the importance of these resources for our life.
