Activating Strategy NOW Write it on the cover of your Erosion foldable! Erosion Power Teaching
Erosion by Human Activity Human activity causes 10 times more erosion of the continental surface of the Earth than all natural processes combined.
Why does this matter? Earth's surface involves a balanced process, where new soil forms at about the same rate as it erodes. • If humans are stripping soil at that rate, nature won't be able to keep up.
Why is this critical?Two Reasons 1. The Earth's human population is growing rapidly 2. Almost all the land that is capable of producing crops is being used.
