Q:

How does erosion effect humans?

A:

Quick Answer

Erosion effects humans by adding additional toxic organic chemicals and heavy metals to the soil as well as eroding land so that there is less land to farm on. Humans are accelerating the rate of erosion.

Full Answer

Erosion used to only occur through natural erosion, which is caused by the planet. However, now there is human-incuded erosion that occurs in lower elevations. Human-induced erosion is primarily caused by farming, construction and mining whereas natural erosion occurs at the highest elevation levels and is typically caused by earth, wind, water and glaciers.

It is predicted that with the continuing growth of the human population and the continuing soil loss from erosion that humans will face serious challenges meeting food needs. As of 2014, the global cropland had increased by 11 percent since 1961, but the global population had nearly doubled. While erosion on its own might not be considered a crisis and might be considered more of a change, with less land to grow food on and a growing population, it has become a serious problem. Researchers have found that the United States erosion rates are unsustainable and that the erosion rates in Africa, Southeast Asia and Latin America are in even worse shape. A solution to the erosion problem has not been found.

  • Q:

    What causes erosion?

    A:

    Erosion is a process that causes the soil surface to wear out; geological erosion is caused naturally by water, wind or gravity, and accelerated erosion is caused by human use of land. Geologists estimate that 70 percent of soil erosion is caused by human activities like excessive construction, agriculture, surface mining and forestry.

  • Q:

    How can humans reduce soil erosion?

    A:

    The most effective soil erosion reduction methods include the use of diversions and terraces, mulch, and surface cover; however, the most sustainable method of preventing soil erosion is by using the land responsibly according to its capability. Soil type, slope and the land's position may determine its vulnerability to soil erosion.
