Have you ever been annoyed by, or maybe even tripped over, cracked uneven sidewalks caused by tree roots gone wild?  Now instead of destroying the trees responsible for the damage, rubber sidewalks are saving them by slowing the growth of their roots.  According to cleantechnica.com, rubber sidewalks are now being walked on in nearly one hundred cities as an environmentally friendly technology to both preserve trees and reduce stormwater run off.  For those worried about global warming, these rubberwalks also cut down on greenhouse gas emissions since rubber would replace concrete construction with recycled tires and plastic. So next time you fall off your bike, you might just bounce right back up.
