Roofs, sidewalks, patios, and asphalt parking lots are examples of impervious surfaces, where rainwater drains into the public storm drains. Heavy metals, oil, and other pollutants are carried off parking lots in rainwater, which often lead directly to open water habitats, where fish, birds, and reptiles live. In terms of ecological services, trees and grass have been proven to: 1. Remove and store carbon from the atmosphere, 2. Remove certain airborne pollutants, 3. Permits rainwater to seep into the ground as opposed to draining into the stormdrains, and 4. Remove certain waterborne pollutants. Here is a look at how green Google and Yahoo really are and how the meas
