As the national conversation shifts to political finger-pointing, an important environmental question deserves careful scrutiny: What is the best approach to maintain urban water quality?
Flexitarian diets and breeding better livestock can make farming more sustainable. But it will take much more to farm within the planet’s limits
Changes to the landscape and pollution have harmed this vital ecosystem known as the ‘river of grass.’
The UK’s proposed Planning Bill may make it easier to build river-polluting chicken farms.
Blue, green orange, brown − water comes in many colors, depending on what’s in it.
Festivalgoers could be adding nitrogen and phosphorous to the rural environment at concentrated hotspots by weeing in the open air.
Did the Green Revolution, which brought high-tech agriculture to developing nations in the 1960s, prevent famine? Recent research takes a much more skeptical view.
Developers will no longer have to offset nutrient pollution from new housing projects – the UK government say this won’t degrade water quality.
Conventional agriculture offers farmers few choices about which crops to grow or how to raise them. A new approach uses computing to construct better strategies with lower environmental impacts.
Seagrasses need light to remain resilient to marine heatwaves – water pollution disrupts that balance.
The tiny organisms that cause harmful blooms of algae can have a big impact on your trip to the shore. A toxicologist explains what causes these events and how to keep people and pets safe.
Scientists are predicting a record sargassum bloom in 2023. It’s already starting to wash up on beaches in Florida and the Caribbean and cause a stink.
Shall I order the chicken, or the salmon? What does the science say about reducing pressure on the environment? When you take a big-picture view, the results can be surprising.
The US Supreme Court opens its 2022-2023 term with a case that could greatly reduce federal protection for wetlands. Here is what makes these ecosystems valuable.
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.
It’s possible to feed the world’s 7.8 billion people with more environmentally friendly farming practices. Here’s how.
New research shows that one-third of yearly nitrogen runoff from Midwest farms to the Gulf of Mexico occurs during a few heavy rainstorms. New fertilizing schedules could reduce nitrogen pollution.
Cuba’s sustainable approach to farming has protected its rivers from the kind of nutrient pollution that impairs many US waterways.
Warmer waters, heavier storms and nutrient pollution are a triple threat to Great Lakes cities’ drinking water. The solution: Cutting nutrient releases and installing systems to filter runoff.
