Explain some harmful effects of agricultural practices on the environment.

The agricultural practices has severe harmful effects on environment which are as follows:

1. Change in the climatic conditions: Due to growing a selected species on a large area of land i.e. monoculture results in change in the climatic conditions of that area.

2. Since, for agriculture, forests are being cut down to clear the area for crops cultivation. This deforestation has led to the decrease in the ground water as it affects the natural process of recharging of ground water.

3. Due to growing of crops or cultivation of land, the soil has now less nutrients and also, it has led to various conditions like soil erosion and desertification.

4. Since ground water has been used for irrigation facilities by constructing tube-wells, so it has led to shortage of water at many places.

5. Use of pesticides and fertilizers has resulted in soil pollution, air pollution and water pollution.
