A typical urine-diverting toilet collects solid and liquid waste, which could be processed into fertilizer, removing nitrogen from the waste stream
Considering that we all flush at least three times a day, it’s surprising how little we know about where our waste goes. Into a white bowl and then down a pipe— never to be seen, smelled, or thought of again.
But as many Cape Codders are beginning to realize, that’s not really the case. The by-products of our waste are seeping out of underground septic systems and into the groundwater, flowing finally into coastal ponds. The nutrients are harmless by themselves, but in concentrated form, throw off the ecological balance of sensitive estuarine systems.
Though there are many nutrients and “contaminants of concern” to be worried about, nitrogen is known as the culprit for changing pristine harbors into algae-filled swamps, devoid of marine life. Or so we fear. (more…)

Most people, when they think about Cape Cod, think about seafood. But very little of the shellfish we consume actually come from local waters! After decades of decline, the local shellfish industry is woefully underdeveloped, while overfishing and over-development of waterfront housing has caused the downfall of a once-fertile industry.
Given that its now easier to find oysters from Duxbury and mussels from Prince Edward Island than it is to get locally-sourced seafood, this locovore’s dilemma begs the question: which came first? The shellfish or the septic system? The problem or the solution?

A major chemistry experiment is taking place in the world’s oceans, with potentially irreversible effects on marine ecosystems and commercial fisheries.
According to scientists at the Woods Hole Oceanographic Institution, 30% of the world’s carbon dioxide (CO2) emissions, known to be a leading cause of global warming, are being absorbed by the ocean. Small coincidence that over the past 50 years of global industrialization, rising CO2 emissions have also led to a 30% increase in the average acidity of ocean surface water.
This phenomenon is just starting to attract the attention– and alarm– of policymakers and the shellfish industry. I talked to Scott Doney and Sarah Cooley at WHOI to find out why.
