Many other types of conservation efforts, such as plant conservation and animal conservation, depend on soil conservation.Poor farming methods, such as repeatedly planting the same crop in the same place, called monoculture, deplete nutrients in the soil. erosion: The removal of soil from the land's surface by water, wind, ice, or gravity. Soil is fundamental to all life on earth. The soil is literally the foundation of plant life. Heres what the science says. Diamond, J. Soil filters our water and grows our crops, but 95 percent of the food we eat is grown in topsoil thats being degraded by human activity. Some predators are useful for keeping the populations of other animals at manageable levels. In addition to contamination, chemicals used on crops can be toxic to important beneficial insects, such as bees, as well as fish and bird populations. Academic Press, Inc., 1995. This carbon helps to provide energy for the growth of microorganisms, and to promote the formation of new cells. But when we damage the soil, water systems become disrupted, food production declines, and carbon is released into the atmosphere. A detritivore is an animal that eats dead matter and adds nutrients back into the soil through its waste. Governments can enact policies and regulations that encourage resource conservation, such as incentives for using renewable energy sources or penalties for excessive resource consumption. Through conservation, people can reduce waste and manage natural resources wisely.The population of human beings has grown enormously in the past two centuries. Our soils are the basis for agriculture and the medium in which nearly all food-producing plants grow. Indeed, soil quality is directly linked to food quality and quantity. As soil quality decreases, so does the nutritional value of the crops that are produced. Simon and Schuster, New York. Thirsty FoodPeople require about 2 to 4 liters of drinking water each day. At least 50-60 years must pass before a burning forest area is reforested and restored. We might imagine soil as endless and indestructible: it is neither.

In the agroecosystem fertilizer (e.g., manure, compost, chemical) is applied and nutrients are removed through plant harvest (red arrows). B. Secondary macronutrients are needed in smaller quantities, are typically in sufficient quantities in soil, and therefore are not often limiting for crop growth. Computers, televisions, and mp3 players are other products contributing to e-waste. The U.S. Environmental Protection Agency (EPA) estimates that Americans generated more than three million tons of e-waste in 2007.Electronic products contain minerals as well as petroleum-based plastics. Soil also acts as a purifier: As surface water travels through the ground to replenish aquifers, soil filters out toxins and impurities, making it drinkable. Sparks, D. L. Environmental Loamy-textured soils are commonly described as medium textured with functionally-equal contributions of sand, silt, and clay. If used wisely and efficiently, however, renewable resources will last much longer. Natural Resources are important part of our life; Caring for Natural Resources reflects ones Soil conservation aims to mitigate these threats.
