When people think of ponds, some may think ‘green’ is just for algae. Today, however, ponds can be crystal clear and environmentally ‘green.’ In fact, ponds are esthetically beautiful, incredibly relaxing, and offer a variety of ecological benefits. According to the Environmental Protection Agency (EPA), for instance, gasoline-powered landscape equipment (e.g. mowers, trimmers, blowers, and chainsaws) used to maintain traditional landscapes account for more than five per cent of urban air pollution. Further, residential application of pesticides is typically at a rate 20 times that of farmers per acre; yard wastes (mostly grass clippings) comprise 20 per cent of municipal solid waste collected, and most still ends up in landfills; and a lawn has less than 10 per cent of the water absorption capacity of a natural woodland—one reason for suburban flooding. Replacing all or at least some portions of a lawn with a pond can actually support the environment.
