Golf is a multibillion dollar industry in Florida. There is a great deal of waste that inherently accompanies the sport (travel, gear, powering/fueling golf carts, concessions, watering and chemical use on grass and grounds, to name a few). As John Barton wrote in Golf Digest, "There are issues about where golf courses are built, about how they're built, and especially about how they're maintained." However, many Florida golf courses have made strides to green the industry. Some courses use non-potable wastewater to irrigate, water smaller areas of the property, irrigate more efficiently, mow less and use grasses that require less water. Many use organic fertilizers instead of conventional pesticides. Others (such as Cheeca Lodge on Matecombe Key) work to restore endangered species' habitats and serve as reserves for those animals.
