Studies have shown that human interaction with a beautiful space can
improve behavior and mental health. Green spaces can:
• Restore a mind of mental fatigue and help a person focus.
• Help children develop emotional, cognitive, and behavioral connections.
• Encourage creativity and intellectual development.
Economic Impacts
The green industry contributes signifi cantly to the economy of the United
States. In recent years, billions of dollars were contributed through annual
revenue to the US economy by the green industry. Although many jobs may be
seasonal, the landscape service sector of the green industry employs the most
workers with more than 1 million employees throughout the United States.
Future of the Green Industry
The green industry continues to be the fastest growing segment of
the national agricultural economy. As people express more interest in
eco-friendly landscaping and sustainable ways
to maintain it, the green industry will continue to
grow. Ways in which green industry businesses can
capitalize on this opportunity include:
• Cultivating and promoting water-wise plants
(plants that use less water).
• Incorporating edibles into landscaping designs.
• Encouraging rainwater harvesting and use.
• Installing sustainable landscapes.
• Using integrated pest management (IPM).
• Offering organic or chemical-free services.
• Promoting new technologies such as
permeable pavers.
• Designing affordable, green outdoor living
spaces, Figure 4-18.

Living Roofs

A green or living roof is one that
is partially or completed covered with
soil, vegetation, and a waterproof
membrane. Aside from being beautiful,
living roofs provide insulation, reduce
water runoff, and create a habitat.
However, roofs must be supported
well, as green roofs, especially when
wet, are extremely heavy.
