Life on Earth depends on resources like soil, water and air, and energy from the Sun.
Uneven heating of air over land and water-bodies causes winds.
Evaporation of water from water-bodies and subsequent condensation give us rain.
Rainfall patterns depend on the prevailing wind patterns in an area.
Various nutrients are used again and again in a cyclic fashion. This leads to a certain balance between the various components of the biosphere.
Pollution of air, water and soil affect the quality of life and harm biodiversity.
We need to conserve our natural resources and use them in a sustainable manner.
