Factories burn fossil fuels and simultaneously release pollutants in the air; hence, man-made CO2 is formed. Since the pre-industrial era, man-made CO2 has increased by a third with a consequential change in global temperatures. By creating this man-made CO2, the carbon cycle has been disrupted and the excess CO2 is...
