Management of Natural Resources


List any two causes of our failure to sustain availability of underground water.[Foreign]


Two causes of our failure to sustain availability of underground water are:

  1. Rising population: As the population increases, demand for water increases resulting in depletion of underground water level.
  2. Industrialization: Industries need more and more water to manufacture products. With growing industrialization, demand for water increases which results in reduction in the availability of underground water.
