What are Our Basic Needs?

The five basic needs of every human being are air, water, food, clothing and shelter.

  • The blood absorbs oxygen and circulates throughout our body.
  • We inhale oxygen gas into our bodies and exhale carbon dioxide gas out of our bodies.
  • Air is essential for our survival. To breathe clean air, we must keep the air clean by preventing air from getting polluted.


  • Water is essential for all life on Earth. We can’t survive without water for more than four or five days.
  • Water is essential for drinking, bathing, washing, irrigation, cleaning, etc.
  • Nearly two-thirds of our body is water. Water helps in circulation and excretes waste products.
  • The electricity which we use is also produced mainly by water.
  • Water is essential for animals, plants and all living beings surviving on the Earth.
  • We must drink eight glasses of water a day. Therefore, we must take care to preserve and keep the water clean. Therefore, avoid polluting water and wastage of water.
