Answer 1

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.

Deforestation: 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.

Pollution: Use of synthetic fertilizers and pesticides creates soil pollution, water pollution and air pollution
