Nature’s Cleaners: Balancing the Biosphere

Arguably the most basic law of the biosphere is this: waste matter must be recycled into fresh building blocks if life is to continually renew itself. To illustrate this principle, this program, divided into 10-minute segments for easy inclusion into lectures, features close-up photography of carrion beetles reducing a rat carcass, pill bugs and worms turning leaves into humus, dung beetles dealing with animal droppings, microorganisms decontaminating sewage at a wastewater treatment plant, and bacteria devouring industrial pollutants. Viewed together, these five very visual episodes underscore the interconnectedness of all living things. (51 minutes)
