Explanation:

Great lengths of mountains, thriving ecosystems, the ever-spreading sky together with the lithosphere, hydrosphere and atmosphere create a saga called “Nature”. Rich both in terms of its scenic beauty and replenishing resources, nature accounts for supporting life in different shapes and forms on our planet.

Every member of the living world obtains its life support from nature. Nature guides the cycling of air, water and life between the different constituents or spheres on Earth. The treasures in nature not only provide for our basic requirements of survival but also fuel the raw materials to support factories and industries on which the modern world primarily runs.

Since the population is increasing at an exponential rate largely in India and many parts of the world, the “use” of resources has now turned to depletion. Adding to this, are the excessive levels of atmospheric and environmental pollution. Industrial wastes, unchecked use of vehicles, illegal cutting of trees, poaching of animals, nuclear power plants and many more are contributing to the disruption of the natural systems and global warming.

Student clubs, organizations and the government have taken measures to curb the exhaustion of nature and extinction of the life it supports. Some of these include:

⇒Adapting sustainable modes of survival

⇒Conserving all forms of energy

⇒Limiting the use of vehicles that release pollutants

⇒Mass afforestation in different areas

⇒Implementing methods to meet the minimums tree cover required

⇒Switching to organic agriculture as much as possible

⇒Reusing and recycling goods

⇒Spreading awareness among people near us

History is a witness to the extinction of organisms as large as dinosaurs and the survival of animals as minute as ants. In addition to other factors, it is inevitable to remember that nature can take up both constructive and destructive roles. Through natural calamities, pandemics and natural crisis situations, nature has well explained the need for us to conserve nature so as to continue life on Earth for our future generations.
