"Walking our dog Silas has given me a great opportunity to observe nature. I live just a couple of blocks away from campus. Over the past few weeks, I have seen a great blue heron, turtles, a fox in our front yard, and located the nesting area of a pair of barred owls. I have also observed the sequence of flowers blooming from daffodils to tulips and lilacs, and finally peonies. Silas has discovered pollinators, including bees and butterflies. These walks provide moments of beauty and are calming because of the patterns and cycles they reveal."

And here's a quote from one of Dr. Crawford-Parker's favorite books: 
“As a species, we are most animated when our days and nights on Earth are touched by the natural world.”
Richard Louv,  The Nature Principle: Reconnecting with Life in a Virtual Age
