Describe Some Unethical Practices Which Led To Degradation of Natural Resources

The document discusses several unethical practices that lead to degradation of natural resources, including soil erosion, water-logging, soil salinity, and deforestation. Soil erosion is caused by over-cultivation, grazing, deforestation and poor irrigation. Water-logging and soil salinity problems have increased due to irrigation without proper drainage. Deforestation has reduced forest cover in India from 30% to 19.4% and its causes include urbanization, overgrazing, and demand for wood and forest products.

Describe some unethical practices which led to degradation of


natural resources
Answer-
There are many unethical practices that humans are following
nowadays which are leading to the degradation of natural
resources.
Some of them-
1. Soil Erosion and Desertification:
Topsoil is the most fertile soil and it takes centuries to build.
Improper human activities can remove it, resulting in arid
patches of land. Natural resources get degraded not only by
pollutants, but also by improper practices of their utilisation
and maintenance.
Soil erosion is caused by human activities like over-cultivation,
unrestricted grazing, deforestation and poor irrigation. All these
practices lead to the removal of top soil. Desertification is also a
major problem these days, that occurs mainly due to
urbanisation.
2. Water-Lodging and Soil Salinity
Irrigation without proper drainage of water leads to water-
lodging in the soil. It draws salt to the surface of the soil.
Deposited salt starts collecting at the roots of the plants and
affect the plant growth and productivity. It is extremely
damaging to the agriculture. Water-lodging and soil salinity are
some of the problems that have come in the wake of the Green
Revolution.
3. Deforestation-
It is the conversion of forested areas to non-forested area.
Almost 40% forests have been lost in the tropics, compared to
only 1% in the temperate region. In India, at the beginning of
the 20th century, forest covered area was about 30% of land,
whereas by the end of the century, it reduced to 19.4%. The
National Forest Policy (1988) has recommended 33% forest
cover for the plains and 67% for the hills.
Reasons why there is deforestation-
(a) Urbanisation
(b) Overgrazing by animals
(c) Forest fires
(d) Demand for wood and other forest products

Effects of Deforestation:
(i) Increased levels of CO2 concentration in atmosphere.
(ii) Loss of diversity due to habitat destruction.
(iii) Disturbs hydrologic cycle.
(iv) Leads to soil erosion.
(v) Desertification also occurs in extreme cases.
After cultivation, the area is left for several years so as to allow
its recovery. This same process is repeated at some other area.
In initial days, there was ample recovery time, but now-a-days
with increasing population and repeated cultivation, this
recovery phase is done away with, resulting in deforestation.
