Coverage of eutrophication since January 25, 2021.

Humans As Drivers of Evolution

"...[p]ollution, eutrophication, urbanization, habitat fragmentation, climate change, domestication/agriculture, hunting/harvesting (including fishing), invasion/extinction, medicine and emerging/disappearing diseases..."


Natural Allies: Great Lakes Water Quality

"...Pollution across the Canada-US water border, particularly from Detroit, had been one of the main reasons for including a clause about pollution in the 1909 Boundary Waters Treaty. Shortly after its creation, the International Joint Commission (IJC) addressed transboundary water pollution in the Niagara, Detroit, and St. Clair Rivers..."


Waste Not, Want Not

"...The precepts of circular economyreusing water, using biodegradable plastic, composting food leftovers so they can be returned to the soil rather than become landfillare among the hottest ideas of our century. But what about recycling what our food becomes after we eat it? Yes, that means excrement, a critical substance in the thoroughly functioning circular economy, seems to be left out of the equation..."


Turf Algae and Kelp Forests

"...But as multiple studies show, these diverse ecosystems are under threat. Climate change and human activity have led to the disappearance of more and more of them. Over the last decade, write the authors, an emerging pattern has been that kelp forests increasingly are replaced by turfs, changing the reef seascape from a complex forest to a structurally simple mat of low-lying algae..."


Human rights could address the health and environmental costs of food production Corporate Knights

"...Industrial food production is a major driver of the planetary environmental emergency. Food systems are responsible for21 to 37 per cent of global greenhouse gas emissions, 70 per cent ofwater useand80 per cent of the pollutioncausingeutrophicationand marine dead zones..."


Do's and Don'ts / Save Owl's Head

"...Shallow marine environments have been degraded by human intervention to disastrous extents. Along the Northeastern shores of North America, about of all eelgrass is gone as a result of degraded water quality, caused by pollution that causes eutrophication (oversupply of nutrients, leading to a decline in species diversity and a rise in opportunistic single species), overfishing, massive sedimentation and disease. But while Nova Scotias shores, especially our Eastern shore, are still relatively undeveloped, warming oceans also pose a threat to these ecosystems..."



"...Coastal bays are known as semi-enclosed signature and long water retention time compared with river-dominated estuaries. In fact, they serve as links between rivers and oceans to transport organic carbon. However, they were universally exposed to high fluxes of nutrients from intensive anthropogenic activities such as sewage discharge and aquaculture industry with the rapid urbanization due to their locations near human settlements..."


New 'Swiss Army knife' cleans up water pollution

"...Phosphate pollution in rivers, lakes and other waterways has reached dangerous levels, causing algae blooms that starve fish and aquatic plants of oxygen. Meanwhile, farmers worldwide are coming to terms with a dwindling reserve of phosphate fertilizers that feed half the world's food supply..."


Research: Countries in violation of Baltic Sea Convention, polluting marine environment

"...The countries made a commitment 20 years ago to implement 10 specific reduction measures in their national legislation on agricultural pollution - e. g. featuring minimum storage capacity for manure and regulations on animal densities..."


Stirling experts develop artificial intelligence to monitor water quality more effectively

"...Mr Werther said: "To understand the impact of climate change on freshwater aquatic environments such as lakes, many of which serve as drinking water resources, it is essential that we monitor and assess key environmental indicators, such as trophic status, on a global scale with high spatial and temporal frequency..."


What is sustainable agriculture? ECO Canada

"...Some problematic areas that are primed for improvement include greenhouse gases (GHGs) from food waste decomposition, the effects of fertilizer and pesticide use on wildlife and surrounding areas, the eutrophication (growth of algae in water sources leading to the eventual die-off of all fish and plants) and monoculture agriculture (where one crop is grown on the land at a time) which can lead to land degradation making the land unsuitable for further farming..."


Study finds water quality improvements in Maryland's Choptank River

"..."The eutrophication of the Choptank estuary is a microcosm of the Chesapeake Bay as a whole," said University of Maryland Center for Environmental Science Professor Emeritus Tom Fisher. "The data presented here indicate that public and industrial investments in reductions of atmospheric emissions and upgrades to wastewater treatment plants have improved estuarine water quality in the Choptank.
