Two problems that today's agriculture has caused is soil erosion and a decrease in biodiversity in the environment. This is especially due to mono-cropping of large tracks of land. Lands cleared for agriculture almost immediately begin to erode away, usually by wind or running water. Due to monocropping, the reduced variety of plants on the environment causes a consequent deduction in a variety of animals in the region such as pollinators due to the availability of only one type of plant for pollination.
