Explain some harmful effects of agricultural practices on the environment.

Answers (1)

Some harmful effects of agricultural practices on the environment are as follows:
(i) Soil degradation: loss of soil fertility because of extensive cropping. Some of the nutrients cannot be replaced naturally due to the high demand of the crop.
(ii) Pollution: Soil, water and air pollution caused by the use of synthetic fertilizers and pesticides. The majority of pesticides are health hazardous due to bio-magnification. The harm caused increases when we move from lower trophic levels of a food chain to higher trophic levels.
(iii) Water shortage: Excess use of groundwater for agriculture lowers the water table. This makes the underground water go deep into the ground.
(iv) Deforestation: Indiscriminate falling of trees for agriculture has resulted in the loss of habitat for wildlife. A natural ecosystem is damaged because of this.
