Water

The 2026 Walk of Water Photostory Contest is offering $9,000 in prizes for photographers documenting the hidden side of water, from wastewater and pollution to sanitation workers, public health and clean-water solutions.

Water from air sounds like magic: machines pull moisture from the atmosphere and turn it into drinking water. But atmospheric water generation comes with an energy cost, making clean energy essential if the technology is going to help solve water scarcity without worsening climate change.

From Antarctica and South Georgia to the Galápagos and Thailand, fragile destinations are finding ways to manage tourism without shutting visitors out. Visitor caps, conservation fees, biosecurity rules and controlled access can reduce environmental damage while helping fund the protection of wild places.

Rather than retreating from climate change work, the Jewish Climate Trust organization has backed a new initiative designed to strengthen both climate action and Jewish community.

Microplastics are showing up everywhere—from dollar store toys and synthetic clothing to bottled water, toothbrushes and even human sperm. A new Ocean Conservancy survey finds that nearly 9 in 10 Americans are concerned about the health impacts of microplastics, while support is growing for tougher regulations. As scientists uncover plastic particles in the heart, placenta and reproductive organs, the question is no longer whether microplastics are affecting our lives, but how much damage they are already doing.

Immersing religious idols in Canada's lakes, rivers and coastal waters remains a contentious issue. While the practice is an important tradition for many Hindu communities during festivals such as Ganesh Chaturthi, environmental regulations in many jurisdictions prohibit the disposal of foreign materials into natural waterways, even when the objects are intended as religious offerings.

The Great Lakes may look pristine, but a new cleanup report reveals a growing tide of plastic pollution beneath the surface. From cigarette butts and food wrappers to tiny plastic fragments and discarded nicotine pouches, researchers are finding evidence that everyday consumer waste is making its way into North America's largest freshwater ecosystem. New technologies, including Canada's first BeBot beach-cleaning robot, are helping scientists understand how plastic travels through lakes, shorelines and stormwater systems before breaking down into microplastics.

Deep below the ocean's surface, in a dimly lit region known as the twilight zone, millions of fish are being caught every year. Scientists say the consequences are largely unknown.

Now researchers at the Woods Hole Oceanographic Institution (WHOI) in the US say they have developed a way to predict coral bleaching five to six months before it occurs, potentially giving reef managers enough time to intervene and save vulnerable corals.

That means the water dripping from your air conditioner may already be usable for gardening, cleaning, flushing toilets, topping up humidifiers, or cooling systems — instead of disappearing into the sewer. A new study. Is it safe?

A retired Swiss biology teacher has built one of the most unusual diving devices ever featured on Green Prophet: a sleek, fish-shaped underwater breathing...

AI makes it easy to dream, develop, and create images of what could be world-changing ideas, until the reality sets in. A new project making the rounds is Aqua Solaire, an allged French concept for a solar-powered desalination vessel designed to bring drinking water to coastal communities facing drought, storms, and infrastructure failures.

The Hydrophilis rebreather is a new scuba system that could make diving safer and more fun.

Does the jara or clay jug concept purify and cool water?

As tensions rise in one of the world’s most critical maritime chokepoints, the ripple effects go far beyond oil—touching food systems, climate pressures, and regional stability
