Shannon Blackburn is a certified Texas Master Naturalist (Alamo Area Chapter, Class #36) with a Bachelor of Business Administration in Information Systems from the University of Texas at San Antonio.

She sees parallels between the “overview effect” astronauts experience when they see Earth from space, learning to appreciate Earth’s biosphere as a connected whole, and the similar effect children and adults experience when they’re in nature and begin to appreciate it as an interconnected web, of which they are a small part.
