Based on various estimates of the number of species on Earth, we could be losing anywhere from 200 to 100,000 species each year.We need to protect biodiversity to ensure we have plentiful and varied food sources. Soils in all climates, including Arctic ecosystems, are essential to the global carbon cycle. Browse USDA programs and services that could help your forest land. The BBC reports that the thawing of permafrost a type of soil in the Arctic that holds an estimated 1.5 trillion tons of carbon (more than Earths atmosphere and forests combined) is releasing both carbon and poisons, such as toxins and diseases, into the atmosphere. Water is vital. They protect soil by reducing runoff. This relationship between humans, the earth, and food sources affirms soil as the foundation of agriculture. Healthier soil absorbs more carbon, reducing the effects of greenhouse gases. Healthy soils conduct the Earths energy, which is important for life. For those working in sustainability, an understanding of soils role can create opportunities to develop new solutions and promote stewardship of our environment. But when we damage the soil, water systems become disrupted, food production declines, and carbon is released into the atmosphere. The U.S. Department of Agriculture (USDA) reports that contour farming can reduce soil erosion by as much as 50%. The micronutrients, or sometimes called trace nutrients, are needed in very small amounts and, if in excess, can be toxic to plants.

Species Spotlight. You cannot download interactives. People in China and Mexico, for example, reuse much of their wastepaper, including writing paper, wrapping paper, and cardboard. Different crops, with different root systems and leaves, help slow erosion. Surface soils are composed of approximately 1 to 6% organic matter, with SOM decreasing with depth (Brady & Weil 2002). At least 50-60 years must pass before a burning forest area is reforested and restored. Poorly managed soil can release excess carbon dioxide, a greenhouse gas that contributes to climate change. Any interactives on this page can only be played while you are visiting our website. As soil quality decreases, so does the nutritional value of the crops that are produced. Implementation of agricultural best management practices (BMPs), and through the practice of conservation agriculture, the rate of soil loss can be reduced to approximately equal the rate of soil formation, although often still greater than that in natural systems (Table 2). Topsoil is used to grow 95 percent of our food, and it is disappearing ten times faster than it is being replaced: Americas corn belt has already lost much of its topsoil, threatening livelihoods and communities as well as food supply.

Figure 4:Damage to agricultural field in Washington (United States) resulting from water erosion. In addition to soil erosion, intensive land use has resulted in deforestation, water shortages, and rapidly increasing desertification of vast areas of the globe, all of which threaten the sustainability of our agricultural systems. Oxford University Press, 2008. However, there are other good reasons to limit our fossil fuel use.
