Overgrazing can reduce edible plant life in an area, cause weeds to become more prevalent and can cause erosion of the soil. This phenomena is usually the result of too many animals living and eating in one location, but it can also be caused by poorly managed farming methods.Know More
There are many signs that an area is suffering from overgrazing, including animals running out of palatable food. Overgrazed pastures feature a variety of short grass species including blue grass instead of orchard grass and other more appealing tall grasses. When this happens, livestock is usually fed supplements of hay throughout the year.
Livestock that has been forced to feed in a pasture area that has been overgrazed tends to not gain as much weight as they should going into the cooler months. As a result, it is harder to keep the livestock healthy during low temperatures.
Overgrazing can be corrected with replanting and an application of lime and a variety of fertilizers. It can take many years for soil to replace the organic materials needed to grow tall grasses and to repair the damage done by overgrazing. One way to prevent overgrazing from occurring is to make sure livestock are rotated in different pastures throughout the year.Learn more in Natural Resources
The effects of natural resource depletion vary depending on the type of resource. Reduced water quality affects humans and animals by reducing the amount of healthy and safe drinking water, while the rapid use of fossil fuels introduces foreign and harmful toxins into waterways, the ground and the atmosphere, and affects human populations by increasing the cost of transportation.Full Answer >
Erosion changes the Earth's surface by a process of breaking down and displacing soil and other material caused by wind, rain and other types of weathering. Erosion may cause soil in a region to be loosened, transported and deposited in a new area.Full Answer >
By definition, wind erosion involves the erosion, transportation and deposition of soil by the wind, according to Dictionary.com. Wind erosion is often worse during dust storms. Poor farming practices by humans combined with drought conditions such as occurred during the 1930s in the United States increase wind erosion.Full Answer >
The effects of erosion are varied, but the most obvious effect is the removal and destruction of land. Whether caused by wind or water, erosion leads to the displacement of soil, rocks, plants and seeds. These direct effects can often lead to broader consequences, including shrinking habitats for animals, accumulation of sediments, the removal of nutrients and other negative effects.Full Answer >
