Why is erosion bad?

Erosion can disrupt an environment completely: less land, several necessary nutrients are taken from the environment, and erosion gets faster and faster as it wins its battle over land.

“Erosion is one of those problems that nickels and dimes you to death: One rainstorm can wash away 1 mm (.04 inches) of dirt. It doesn’t sound like much, but when you consider a hectare (2.5 acres), it would take 13 tons of topsoil — or 20 years if left to natural processes — to replace that loss,” David Pimentel, professor of ecology at Cornell said. “And that kind of loss occurs year after year by wind and rain around the world.”
