What Makes the Environment ?

In the entire universe, only the Earth has humans, animals, birds, and plants. Because of air and land, life developed here. The Earth has three layers :

Hydrosphere (Jalavaran): oceans, glaciers, rivers, and rain. This water cycle keeps all living things alive. Atmosphere (Vataavaran): the air. Oxygen in it gives life to animals and birds. Lithosphere (Mrudaavaran): The soil layer on the Earth’s surface, soft up to 33 km deep.

 It has small creatures like worms and insects. Seeds sprout here to become trees, and farming also happens in it. There is also a fourth layer: the Biosphere (Jeevavaran) - all living beings on Earth. Together, these four layers make up the environment. The Sun is the main source of energy for the environment. Humans and animals live on land. Birds live in the air. Aquatic animals live in water. If the environment is clean and pure, all can live and grow well.
