Researchers have shown that humans make a significant contribution to erosion, and may be as much as 15 times more powerful than the impact of natural erosion.
Humans mostly increase erosion because of agriculture and poor farming practices which strips the soil quicker than the Earth can create new soil. Other factors are deforestation, mining and development or construction. These all mean that sand and rocks are manually removed from the Earth’s surface.
Humans also have the power to help reduce the impact of their erosion of Earth’s surface. This can be done by re-vegetating areas so that plants roots can act as a barrier to erosion.
