Oceans more vulnerable to agricultural runoff than previously thought, study finds

...hellfish poisoning, which can shut down mussel and clam harvesting for long periods of time. Another concern is hypoxia, or oxygen depletion, caused by excessive algae growth. As the algal mass sinks, it is consumed by bacteria, which use up most of the oxygen in the water as they multiply. The result is...
