Air and water are necessary for all living organisms and form the basic principle of existence of life on earth. Water is also required for various industrial and domestic needs of human beings which are increasing with the growing population. Soil or land is required for producing food and shelter by animals and plants. Forests or trees are beneficial in many ways. From wood, to medicines, to paper, to almost every other essential commodity; trees provide us with all. Fuel reserves are required for almost all domestic and industrial purposes. Thus, we see that our existence is impossible without these natural resources.
What is of great concern is that due to the ever growing demands, humans are exploiting these natural resources ruthlessly which risks our existence. We are using these resources to such an extent for our demands which leads to exhausting of these resource reserves and consequent depletion of the quality. Thus earth shall soon reach the brink of irreparable damage. It leads to great environmental concerns like pollution, global warming and consequent effects like disturbance in water levels, critical damage to the earth. This creates the need to conserve the natural resources.
We can do that in a number of ways. Water needs to be conserved as the potable water levels have come down. We can limit the water use at domestic levels. We can recycle water and reuse it wherever possible. We should prevent pollution of water sources. Forests are being exploited ruthlessly. So we should prevent deforestation and find alternative measures for meeting all needs. Alternative resources like solar power, wind energy, synthesized materials etc. help us meet our demands in a sustainable way. Sustainable Development ensures meeting present human needs taking care of the environmental balance and future requirements. Nowadays, the concept of Green Technology is introduced to take care of advancement with natural preservation. Thus, all such measures can help us conserve the natural resources effectively
