"എ.കെ.ജി.മെമ്മോറിയൽ എച്ച് .എസ്.എസ് .പിണാറായി/അക്ഷരവൃക്ഷം/OUR ENVIRONMENT" എന്ന താളിന്റെ പതിപ്പുകൾ തമ്മിലുള്ള വ്യത്യാസം

The part of the environment where life exists is called Biosphere. All the living beings, plants, animals, birds and human beings are part of the Biosphere.

The non-living parts of the environment has three main parts. They are:

The Atmosphere is the air which consists oxygen, hydrogen, nitrogen, carbon dioxide and other gases.

  The Hydrosphere consists water bodies. All oceans, seas, rivers, ponds, lakes etc. make up the Hydrosphere.

Ecology comes from the Greek word 'Oikos'. The word means a place to live in.  Ancient Greek philosopher such as Hippocrates and Aristotle were the first thinkers who discussed ecology in their studies on natural history. Biotic is the name given to the living parts of an ecosystem while abiotic are the non-living parts.  

  Ecosystem is the co-existence of different life forms in a given geographical area. The Indian Government has established 18 biosphere reserves in India, conservation of wildlife. India also has 23.39% of its geographical area under forest and tree cover. Out of the 34 globally identified biodiversity hotspots (Global Hotspots), four are from India:

Western Ghats are recently included in World Heritage list.

International Biodiversity Day is celebrated across the globe on 22nd May every year.

  Biodiversity Hotspot is a biogeographic region with a significant reservoir of biodiversity, that is under threat from humans. Around the world biodiversity hotspots support 60% of the world's plants, birds, mammals, reptiles and a number of endemic species and microbes. The Biodiversity hotspots are the treasure houses on this planet, Earth. Our primary needs food, shelter, medicine are all satisfied by rich biodiversity around us.  

  The environmental issues creates very harmful effects of human activities on the bio-physical environment. The major environmental problems are:

State, National and International levels of authorities take strict action against the environmental problems.

  Over the years, a number of acts have been helped to full fill the objectives of the ministry of environment and forest. The regulatory framework consists of following major acts:

  The above mentioned laws and acts which safe guards our Earth and mainly our country, India, treats as a safe heaven.  

At last, I conclude my writings by remembering a famous and the most valuable quote on environment by Mahatma Gandhi, "The Earth, the air, the land and the water are not an inheritance from our forefathers, but on loan from our children. So we have to hand over to them atleast as it was handed over to us." "There is a sufficiency in the world for human's need but not for human's greed."
