Question

What would you do to help maintain the equilibrium in the various bio-geochemical cycles? Explain in brief.

Answer 1

• Bio-geo-chemical cycles always involve the achievement of equilibrium, i.e., a balance in the cycling of the nutrients between the spheres. 
• Human activities that are known to be environmentally unfriendly can disrupt this balance. 
• We should avoid deforestation as trees play an important role in maintaining the balance. 
• We should avoid overuse of fertilizers. The fertilizers get washed away in the nearby water bodies disrupting the balance. 
• Avoid burning of fossil fuels as these fuels release a large amount of carbon in the form of carbon dioxide, thus disrupting the balance. 
• Vehicular emissions is another contributor to the disruption in balance of the various cycles.
• These emissions release oxides of nitrogen and carbon and other hazardous air pollutants. 
• So, we must use better quality fuel like CNG or ethanol to reduce vehicular emissions.
