Maybe you've heard that a truly green household is a grass-free one. There's certainly something to that notion. Artificial turf has a positive impact on the environment by eliminating the need for toxic pesticides and avoiding the potential harm that can result from over fertilizing lawns. Fake lawns also cut down on yard waste, because no mowing means no grass clippings to cart to the curb for trash pickup. In addition, artificial grass is made from many recycled materials, such as old rubber tires, which would have otherwise been destined for the landfill.
