The consequences of a massively connected globe are real — and not limited to disease pandemics.
Scientists are predicting major algae blooms in Lake Erie and large dead zones in the Chesapeake Bay and Gulf of Mexico this summer. Nutrient pollution from industrial corn farming is a major driver.
Fertilizer is a key source of nitrogen pollution which fouls air and water worldwide. Current regulations target farmers, but focusing on producers could spur them to develop greener products.
Scientists have mapped a huge dead zone in the Gulf of Oman, without enough oxygen in the water to support life. This Speed Read explains why dead zones form in waters around the world.
Nitrogen and phosphorus are polluting US waters, creating algae blooms and dead zones. New research confirms that voluntary steps are failing in the Gulf of Mexico and unlikely to work in Lake Erie.
Excess nutrients from farm fields cause widespread water pollution across the U.S. Bioreactors -- essentially, ditches filled with wood chips -- are emerging as a way to reduce nutrient pollution.
Too much fertiliser can kill all life in parts of the ocean. It has happened before – and could do so again.
The same conditions – ultimately tied to nutrient runoff – that created the damaging toxic blooms and dead zones in US waterways of recent years are forecast to return this year.
