Over cultivation, over grazing, and deforestation are all the leading causes of soil erosion, or wearing down of the earth’s soil (Wright & Boorse, 2011). Why are farmers over cultivating? Why is over grazing such a problem? Why is deforestation becoming a problem in the world? The answers are very simple. The solutions are even simpler. The first thing farmers do is cultivate, or till, the land to control the weeds and to bring oxygen to the soil (Wright & Boorse, 2011). The only problem, it leaves the soil unprotected from wind and water, which can have a negative effect by compressing the soil (Wright & Boorse, 2011). On top of that, aeration and filtration can be worse for the land. Aeration and filtration are meant to bring oxygen to the soil, which is what soil needs to stay healthy (Wright & Boorse, 2011). When it has a negative effect, splash erosion occurs. Splash erosion ruins the soil by sealing the top layer and not allowing oxygen through (Wright & Boorse, 2011). Another issue is poor crop rotation. Every few years it is recommended to lay hay and clover to increase the flow of nitrogen. When neglected, the soil degrades (Wright & Boorse, 2011). Where land receives little rainfall, this is called a dryland area (Wright & Boorse, 2011). This is an ideal place to raise livestock. However, taking advantage of this area, by over grazing, poses negativity on the land. When the grass growth doesn’t keep up with the feeding, or not giving back what
