The ancient, enormous fish have lived on Earth for more than 150 million years but changing weather conditions have researchers questioning whether future generations will thrive.
On a cool October morning, members of the St. Croix Chippewa Tribe gathered at the Clam Lake boat landing in northern Wisconsin, carrying five-gallon buckets of small, wriggling lake sturgeon. After a short prayer calling on their ancestors, they tipped the six-month-old fish—raised in the Tribe’s newly built hatchery—into the lake. It was the Tribe’s first sturgeon release and the latest chapter in one of North America’s great freshwater conservation success stories.
Fish are evolving ever smaller in order to survive temperature increases, new research warns. It’s a biological shift that will rob billions of meals from those who rely on fish for protein.
In the world’s waters, fish are making a quiet, biological retreat. The once simple rules of the ocean—grow larger than potential predators—are being rewritten as temperatures reach record highs. Desperate to survive, fish are hitting the fast-forward button on life in a biological shift that will soon impact what ends up on dinner tables globally.
The old, reliable technology has experienced slow growth, but industry leaders see opportunities ahead.
The International Energy Agency’s executive director has called hydropower a “forgotten giant,” and has urged governments to do more to remember it. U.S. President Donald Trump has said hydropower is “fantastic,” a sharp contrast to his disdain for wind and solar.

California Water Board Will Soon Release a New Rule to Limit Water Pollution From Dairies in the State
More than 10 years after environmental groups petitioned for a new rule, the state plans to require the Central Valley Water Board to update its waste regulations for dairies contributing to groundwater pollution.
California dairies are out of balance. Everyone from environmentalists to regulators to the industry agrees that the nitrogen from milk cow manure is ending up where it can pose a health threat.
