It hosts 25% of the world biodiversity, it contains around twice the amount of carbon that is found in the atmosphere and three times the amount found in vegetation, and some 95% of our food is directly or indirectly produced from our soils. Recently an overwhelming majority of climate scientists, believe that human activities are currently affecting the climate and that the tipping point has already been passed. This supply of water can be caused by flooding of the land by seawater, seepage of seawater or brackish groundwater through the soil from below. Curator Stephan Mantel oversees the World Soil Museum at WUR. Often this light-colored soil is used to grow tobacco, coffee, tea and fruit. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. Badlands Rock Formation: Around 500,000 years ago began the formation of this rock out of a plain terrain in South Dakota, USA. This chart to the left shows the main contributing factors to general soil pollution all around the world. These problem soils range from a slightly saline soil condition which reduces crop growth to extensive areas where cultivation is almost impossible.
