Why are plants considered the most essential living things on Earth?

After a long and hard day in the sun, the shade of a tree is the best solace for Man. Our planet is beautiful because of its green plants. In fact, our life revolves around plants, as we come in contact with them in one way or the other.

Plants are the reason we are alive. Our green friends provide the oxygen that sustains animal life. Scientists say that our atmosphere was filled with toxic gases before plants evolved. Photosynthesis, the process of preparing food by plants, produced oxygen as a by-product and made the gas abundant on Earth. This created an atmosphere conducive for animals on Earth, and caused their evolution. Do you know that plants are the only life forms that can make their own food?

Plants make use of light from the Sun to prepare their food. In fact, all the food that we eat comes from plants directly or indirectly. Even if someone is a ‘pure non-vegetarian’, he indirectly consumes plants because the animals that he eats feed on plants. The carnivorous animals eat animals that are dependent on plants and thus indirectly consume plants.

Therefore, there is no life on Earth without plants. Plants store the surpules amount of food that they prepare in their leaves. We consume this for our sustenance. Thus, the whole animal world depends on plants for their existence.
