2. According to NCERT Exemplar Class 8 Science Solutions Chapter 18 Pollution of Air and Water, how does carbon dioxide cause global warming?
CO₂ is constantly released as a result of human activity. On the other hand, the amount of land covered by forests is shrinking. Plants need CO₂ from the atmosphere for photosynthesis, lowering CO₂ levels in the atmosphere. Because the number of trees that consume CO₂ decreases as a result of deforestation, the amount of CO₂ in the air rises. As a result, human activities contribute to the buildup of CO₂ in the atmosphere. CO₂ is a gas that traps heat and prevents it from escaping into space. As a consequence, the earth's atmosphere's average temperature is progressively rising, resulting in global warming.
