O2

World's existence is just because of you, there would be no life without you, world's entire creatures are alive just because of you, almighty gives us boon as you. You are only our life's anticipation, all the live greenery is the source of oxygen, but a very few people have this fascination, just because of human being oxygen is heading towards the stage of cessation; during pandemic we all were endeavour for oxygen. Human for their convenience are making the atmosphere hostile; people must learn a lesson from covid. Humans in itself destroy the indolent and sedate nature of atmosphere by cutting trees. Oxygen is all around, Oxygen is essential for respiration and fire, Oxygen sustains terrestrial life; Oxygen is mixture of nitrogen and other useful gases for the existence of life. It is a very saden thing.....day by day trees are been cut off by humans, If you plant a plant you generate the source of life for many next generation, everyone have to take this sensation.
