Images of the 2011 tsunami did not look as I had expected, and pointed to the sublime, when experience exceeds our frameworks of understanding. My exhibit ‘Salients’ treats this theme.
Nutrient pollution fouls lakes and bays with algae, killing fish and threatening public health. Progress curbing it has been slow, mainly because of farm pollution.
Harmful algae blooms are an increasing problem in Florida. Once nutrients are in the water to fuel them, little can be done to stop the growth, and the results can be devastating for marine life.
This transformation provides lessons for the rest of world, for shifting away from chemical agriculture towards a healthier system for people and the planet.
Populations of freshwater species are in a state of deep decline. But we know why and we can reverse the trend.
Algae blooms have killed hundreds of thousands of fish in the last two weeks, but what exactly are they and how do we get them under control?
Red tide and a blue-green algae outbreak are fouling hundreds of miles of coast, killing fish and driving tourists away from beaches. Some of the causes are natural, but human actions play a big role.
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.
They give us part of the air we breathe but microscopic phytoplankton can also be toxic. They are also on the move thanks to climate change so a new Australian database hopes to monitor any changes.
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.
