Live Earth Rocks

Every time people talk about Live Earth, my mind turns to thoughts of preventing soil erosion. Cryptobiotic soil, also called cryptogamic earth, is certain lichens, mosses, algaes, and microscopic plants binding with the top layers of soil to form a light crust. In arid regions his crust protects land from wind and water erosion, but is extremely fragile and years of growth can be destroyed by simple foot traffic. That's why, when you ignore instructions and leave the park trail to take that bad photo you will never look at, you deserve to have a meathook driven into your brain.

Oh, and Live Earth was a series of concerts too. Gore in 2000!
