Answer: Some of the harmful effects of agricultural practices on the environment are as follows:

Climate Change:
 As farming means growing a selected number of species on a large tract of land, it promotes monoculture. Thus farming affects the biodiversity of a region in a negative way.

 Clearing of forests for agriculture has resulted in loss of habitat to wildlife. Deforestation has also affected the natural recharge process of groundwater.

Soil degradation:
 Intensive farming robs off the soil of its nutrients. In the long run, it can lead to soil erosion and finally to desertification.

Water shortage:
 Over exploitation of groundwater for irrigation has resulted in acute water shortage at many places.

 Use of synthetic fertilisers and pesticides creates soil pollution, water pollution and air pollution
