This document introduces the concept of sustainable landscape maintenance. Sustainability is broadly defined as meeting the needs of the present without compromising the ability of future generations to meet their needs. Sustainability recognizes the interdependency between the environment, human health, and the economy, and considers all three when measuring success. The concept of sustainability is becoming widely accepted, and is now applied to many different industries, including architecture, agriculture, landscape architecture, and the manufacture of goods and materials. This lesson's learning objectives are to identify the key elements to maintaining a sustainable landscape, identify pollutants found in their home landscape, and create a sustainable landscape maintenance plan.
