The earth's atmosphere is divided into several layers, namely-
(1) Troposphere
(2) Stratosphere
(3) Mesosphere
(4) Thermosphere
The troposphere is the layer that extends up to a height of about 10 km from the ground surface. In this layer. the temperature decreases with altitude. This is the layer in which all the weather phenomenon takes place. The Oxygen gas this available in this layer that is required by all the living organisms to exist on earth. It also regulates the earth's atmospheric temperature.
Thus, the troposphere is one of the most important layer of atmosphere.
I think its harmful, because its unhealthy for workers and its harmful to the environment and to the people. Its also a waste of water and it pollutes the air.
A Organism, but I would say Multi Cellular Organism instead of just organism because a Unicellular organism only has one cell, and all higher levels are made of multiple cells
