Suggest any three steps to minimize the environmental degradation caused by the industrial development in India.



Points to remember:

  • Reusing and recycling water in different stages.
  • Using rainwater for harvest
  • Treating hot water and effluents from industries before releasing them into rivers.
  • By legally regulating the over-use of groundwater .
  • Fitting smokestacks in factories to reduce particulate matter .
  • Using oil and gas instead of coal
  • Redesigning machinery and equipment and using silencers in generators
  • Using noise-absorbing materials .

Answer to be written:

Environmental degradation caused by industrial development can be minimized in the following ways:

  • By minimising the use of water for processing by reusing and recycling it in two or more successive stages.
  • By using rainwater to meet the water requirement for harvest .
  • By treating hot water and effluents (liquid waste) from industries before releasing them into rivers and ponds.
  • By legally regulating the overdrawing of groundwater reserves by industries where there is a threat to groundwater resources.
  • By fitting smokestacks to factories with electrostatic precipitators, fabric filters, scrubbers and inertial separators to reduce particulate matter in the air.
  • By using oil and gas instead of coal to reduce smoke from factories.
  • By redesigning machinery and equipment and using silencers in generators to increase energy efficiency and reduce noise .
  • By using noise-absorbing materials apart from personal use of earplugs and earphones.
