The way a conventional backyard swimming pool works is that you use toxic chemicals to kill any living thing in the water, essentially creating a liquid dead zone.
An Austrian company called Biotop Natural Pool uses plants to keep pool water safe. Instead of killing all life, the Biotop system creates an ecosystem where the pool is teeming with life. Pool designs have separate swimming and plant-growing areas of equal size. The plants eat the algae, which would otherwise take over.

Leslie Wickman, Ph.D., is currently director of the Center for Research in Science (CRIS) at Azusa Pacific University (APU). She is an internationally respected research scientist and engineering consultant. For more than a decade Wickman was an engineer for Lockheed Martin Missiles & Space, where she worked on NASA's Hubble Space Telescope and International Space Station Programs, receiving commendations from NASA for her contributions and being designated as Lockheed's Corporate Astronaut. She has also worked as a research scientist with The Aerospace and RAND Corporations on technical and political aspects of various national space and defense issues. Some of her current projects include global climate change research, assessment of future space mission technologies, human factors problems for extreme environments, fighter pilot proficiency training, and a sustainable water reclamation system. As director of CRIS at APU, Wickman's responsibilities include addressing the relationship between science and theology. She has lectured extensively around the world on satellite servicing, astronaut operations, mission planning, and space physiology issues. She is also a dedicated athlete, playing competitive beach volleyball and women's professional tackle football. Wickman holds a master's degree in aeronautical and astronautical engineering and a doctoral degree in human factors and biomechanics, both from Stanford University. She graduated magna cum laude from Willamette University with a bachelor's degree in political science.
Dr. Wickman is also a Christian apologist. What is “the Anthropic Principle” and what does it say about our place in the universe? Is an intelligent creator helpful in explaining the intricate facets of functionality that we discover through the sciences? Do the things that we find require a more than natural explanation? Does the use of the scientific method itself seem to imply theistic presuppositions in order to begin the process of analysis?
Wickman is currently accepting bookings for speaking engagements on various topics, including:
"The Anthropic Principle"
"Our Amazing Universe"
"Dealing with Life's Big Questions"
"Is Planet Earth Just a Lucky Accident?"
"Are We Alone in the Universe?"
"Does God Exist?"
"Who is Jesus?"
"What's My Purpose in Life?"
"The Scientific Method & Christian Apologetics"
"Faith Integration in the Science Classroom"
"Evidence for Faith"
"Science & Scripture"
"Environmental Stewardship: Caring for Creation"
"Living & Working in Space"
