A great number of homeowners yearn for a perfect, green lawn, but this can be problematic when, for instance, there is drought in the United States and hosepipe bans are a possibility in the United Kingdom. Not only that, but the use of fertiliser and pesticide is discouraged. While green, lawns can be decidedly ungreen, figuratively.
Studies have connected pesticide use in schools with illness in staff and students and use at home with a greater prospect of childhood leukemia. Pesticides can even kill. While use of agricultural chemicals declined by 12,189 tons in the United States from 1992 to 1997, chemicals used on lawns grew by 7,747 tons.
