We all know that human beings need a number of things to survive. The most essential two things are surely oxygen and water. These two things are absolutely necessary for mankind. However, what we do not realize is that we are polluting both these things at a very fast rate. If we look at it closely, we’ll see that human activities are causing these two to deplete.
Value of Oxygen
Oxygen is basically a colourless and odourless gas which is a part of several compounds like water as well. Humans along with other mammals require oxygen necessarily. They need it to carry out their daily tasks and smooth functioning of the body.
Even the cells in our body need oxygen to function properly. All the living beings inhale oxygen in their lungs for proper respiration. After that, our cells absorb this gas to distribute it evenly to other cells of the body. Most importantly, oxygen is also stored in our body for emergency use so we can survive critical situations.
