" landscapes are often environmentally insensitive in a variety of different ways. They generally require more maintenance, chemical fertilizers and pesticides, and supplemental irrigation to achieve the desired aesthetic effect. These practices can contribute to a number of current environmental problems, from air and water pollution to consumption of fossil fuels. . . . By utilizing local plant species and arranging them in ways which imitate local ecological communities, natural landscapes usually require less maintenance and are substantially more environmentally sensitive."
