To create space for agricultural lands, a wide area of forested land is cleared down.

Rice and paddy fields as well as the digestive systems of domestic animals release a large amount of methane (a greenhouse gas) into the atmosphere.

Due to repeated growing and harvesting of plants, the soil loses its fertility over time.

When plants are harvested, the barren soil is left vulnerable to erosion.
