प्रश्न
What would you do to help maintain the equilibrium in the various bio-geo-chemical cycles? Explain in brief.
उत्तर
Biogeochemical cycles are the basis of life and play an important role in the maintenance of life on Earth. Any kind of disturbance to these cycles can result in the destruction of life. We have seen from all the biological cycles that plants play a crucial role in these cycles. Plants are required for the existence of life on Earth and any kind of harm to them can directly affect life on Earth. Deforestation due to industrialisation and increased population has resulted in the loss of forest cover on Earth. In order to maintain the equilibrium in biological cycles following steps should be undertaken:
- reduce deforestation
- reduce the carbon imprint
- minimise the use of fossil fuels and encourage the use of renewable sources of energy.
- conserve water
- conserve biodiversity as both plants and animals are a part of these biological cycles.
