Which of these methods is used for conservation of land resource?

The correct answer is Land reclamation.

Key Points

• Land reclamation
  • Land reclamation is the process of creating new land from the ocean, riverbeds, or lake beds.
  • The process of reconverting disturbed land to its former or other productive uses.

Additional Information

• Deforestation:
• Deforestation is the process of removing trees from forests (or other places) on a big scale in order to facilitate human actions.
• It is a major environmental issue.
• Some of the major causes of deforestation are:
  • Agriculture.
  • Logging.
  • Mining and urban expansion.

• Poaching
  • Poaching is an illegal hunting process.
  • Poachers are illegitimate hunters who kill wild animals for their different body parts.
  • These are some examples of animals that are killed for poaching: Crocodiles, rhinos, elephants, lions, and deer.

• ​Indiscriminate use of fertilizers has led to soil pollution, water pollution, and air pollution.
  • Effects of excess use of fertilizers:
    • Oxygen Depletion:
      • When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth.
      • The growth and reproduction of microorganisms reduce the dissolved oxygen content of the water body.
    • Ammonia Toxicity:
      • Ammonia-contaminated runoff from fresh manure application sites is toxic to aquatic life.
      • At high levels, ammonia in surface water will kill fish.
      • Fish are relatively sensitive to ammonia in water.
