soil erosion 

What happens when all of the plants are bulldozed out of a specific area, most severe where there are hills and mountains.
A common sight in the Amazon Rainforest region, Hawaii, Appalacia, Tasmania, Africa, and metropolitan areas all across the USA.
Commonly caused by strip mining, clearcutting, the overgrazing of livestock (especially beef cattle), and evil greedy developers.

This used to be a lush, old growth forest. Thanks to soil erosion, now it looks more like the Grand Canyon.

Food Erosion 

When instead of having a specific portion of food, you keep chipping away at it, usually evenly around the edges, making the portion smaller, while not accepting that you are having some.

What happened to this cake? I swear it was bigger a minute ago. Looks like food erosion.

jizz erosion 

A condition affecting the faces of women, generally middle-aged, often with multiple husbands, in which the face of the woman has started to crack/break down/weather away after years of repeated splashing with the jism of the males she so desperately seeks to please (and get money from). Sign of a woman that is past her prime and has been used up by many beforehand.
