Welcome to Bruce Rettig’s blog, Changing Tides. This blog focuses on topics related to the natural world, the creative process, and general musings. It focuses a keen eye on environmental and social issues and examines how the human spirit might, or might not, correct current trends.

Please visit with an open mind—there are many different viewpoints but we all share the same home.
