The most important element in our lives is oxygen. Trees release oxygen gas into the air when preparing food with sunlight. In order to survive, these oxygen animals take in breathing with their breathing. Again, the carbon dioxide gas that animals emit into the air when they breathe is absorbed by plants during food preparation and helps reduce the levels of carbon dioxide in the environment.
In this way plants help to keep our environment clean and healthy.
Not just oxygen, plants help animals in many more ways.
From the tree man gets wood, from which he makes furniture (such as beds, tables, chairs, benches, doors, windows, etc.). Also, dried twigs of trees are used by people as fuel.
People get flowers and fruits from trees. Many valuable medicines are made from different parts of the tree (such as roots, stalks, leaves) etc. From ancient times the practice of treating various complex and incurable diseases with herbs has been going on in our country.
The roots of the tree help to hold the soil. Planting trees in places where there is heavy rainfall and consequent soil erosion can be greatly reduced. In the old days, passers-by used to rest under the trees in summer and take shelter under the trees to protect themselves from the scorching sun.
