Many Definers may enjoy laying in a lush, green lawn staring up at a blue sky while listening to the latest Sustainability Defined episode. We love that, but it's also important to think about how we got those landscapes and how we can maintain them more sustainably. This episode considers the footprint of all kinds of man-made and maintained landscapes, particularly the around 50 million acres of lawn in the United States. You'll hear about the many impacts of landscaping our environment, including the crazy amount of air pollution that comes from gas powered equipment, as well as techniques you can use to maintain a landscape you enjoy with less impact on the environment. Our expert guest, Dr. Sharon Hall, ecosystem ecologist and professor at the School of Life Sciences at Arizona State University, provides insights from her research on how humans interact with the residential landscape and from her own landscaping experience. Let's put on some gardening gloves as we get our hands dirty diving into sustainable landscaping.

Sustainability Defined is the podcast that seeks to define sustainability, one concept (and bad joke) at a time. Hosted by Jay Siegel and Scott Breen.

Each episode focuses on a single topic that helps push sustainability forward. We explain each topic with the help of an experienced pro, place it within our organizational tree, and help our listeners define what exactly sustainability is, episode by episode.

We have divided our organizational tree into the following seven sectors:

Energy

Cities

Natural Environment

Transportation

Business

Policy

Social

Each episode is categorized under one of our sectors and visually depicted within our organizational tree. The more episodes we complete, the more the tree will visually define what exactly sustainability means.
