For Chinook salmon, the urge to return home and spawn isn't just strong — it's imperative. And for the first time in more than 65 years, at least 23 fish that migrated as juveniles from California's San Joaquin River and into the Pacific Ocean have heeded that call and returned as adults during the annual spring run.
Summers in the Midwest are great for outdoor activities like growing your garden or cooling off in one of the area's many lakes and streams. But some waters aren't as clean as they should be.
That's in part because coal companies have long buried toxic waste known as coal ash near many of the Midwest's iconic waterways, including Lake Michigan. Though coal ash dumps can leak harmful chemicals like arsenic and cadmium into nearby waters, regulators have done little to address these toxic sites. As a result, the Midwest is now littered with coal ash dumps, with Illinois containing the most leaking sites in the country.
Some of the world's most iconic rivers contain antibiotics that exceed safety standards, according to a global study testing hundreds of rivers across six continents.
Thousands of hydroelectric dams are under construction around the world, mainly in developing countries. These enormous structures are one of the world's largest sources of renewable energy, but they also cause environmental problems.
Millions of people across the U.S. have been exposed to toxic PFAS chemicals in their drinking water, according to a new report from Northeastern University and the Environmental Working Group.
Only a little more than one-third of the world's 246 longest rivers remain free-flowing, drastically reducing the diverse benefits that healthy rivers provide to people and nature everywhere, according to a new study by World Wildlife Fund (WWF) and partners.

This is a rough moment to read or listen to environmental news. As we're experiencing a seemingly unending parade of rollbacks and pro-polluter actions coming out of DC, the international science community is ringing the alarm bell on a series of issues that need attention — now. Most notably, last year's IPCC climate report made clear that action needs to happen fast if we are going to stave off the worst impacts of climate change.

The toxic mess left behind from burning coal is a growing, nationwide problem. But we're seeing that state governments can be convinced to do the right thing and clean it up. Recently, North Carolina joined its neighboring state to become a trendsetter in the proper disposal of coal ash waste.
Hurricane Florence, which battered the U.S. East Coast last September, left a trail of ruin and destruction estimated to cost between $17 billion and $22 billion. Some of the damage was all too visible—smashed homes and livelihoods. But other damage was less so, like the long-term environmental impacts in North Carolina from hog waste that spilled out over large open-air lagoons saturated in the rains.
Hog waste can contain potentially dangerous pathogens, pharmaceuticals and chemicals. According to the state's Department of Environmental Quality, as of early October nearly 100 such lagoons were damaged, breached or were very close to being so, the effluent from which can seep into waterways and drinking water supplies.
The groups' research found that in 2018, manure from 515.3 million chickens and turkeys joined the waste from 9.7 million hogs already fouling waters and threatening North Carolinians' health. By scouring satellite data, examining U.S. Department of Agriculture imagery and conducting site visits, EWG and Waterkeeper experts identified more than 4,700 poultry and about 2,100 swine concentrated animal feeding operations, or CAFOS.
World Wetlands Day on Feb. 2 marks the date when 18 nations signed the Convention on Wetlands in 1971, in the Iranian city of Ramsar on the shores of the Caspian Sea. Since that time, scientists have shown that wetlands provide many valuable services, from buffering coasts against floods to filtering water and storing carbon. These five articles from our archive highlight wetlands' diversity and the potential payoffs from conserving and restoring them.
