  • From Fish Waste to Community Wealth

    A government agency in India is turning fishing waste into useful commodities, which help both the environment and the community. Discarded fish parts often littered the beaches near fish markets, leaving a stench and a mess that stigmatized the neighborhood. Now the parts are being processed and sold as fertilizers leading to a cleaner community, less waste, and a much-needed alternative source of income in the fishing community.

  • The frontline of conservation: how Indigenous guardians are reinforcing sovereignty and science on their lands

    Over many months, the Wuikinuxv Guardian Watchmen in British Columbia, Canada, patrol about 2,000 square kilometers of the coast by boat, and they're doing everything from warding off poachers to participating in scientific studies. Since it’s rare to see government vessels monitoring the area, many Indigenous communities throughout Canada have created these guardian programs as a way to conserve and protect their land.

  • Researchers use waste glass to clean up polluted sea

    The beach in Omura Bay in Japan isn’t a normal beach covered in sand: It’s covered in glass. This glass beach, developed by the Nagasaki Prefectural Environmental Health Research Center, is meant to recycle waste from the ocean and promote the growth of shellfish to maintain the water’s health. After five years, the center has seen about 525 clams per square meter, an increase over previous years.

  • How to Plant Millions of Oysters in a Day

    Conservationists are injecting millions of baby oysters into the Chesapeake Bay region to boost the native populations and improve the water quality. With their efforts, they’ve been able to restore 10 tributaries and about 324 hectares of oyster reefs have been restored.

  • Off the coast of Italy, a radical approach to battling illegal fishing: a seafloor sculpture museum

    An unlikely sculpture museum is helping to battle illegal fishing off the coast of Italy, but this one museum you'll have to dive to see. Over 39 sculptures make up this underwater exhibit and serve as a physical barrier to seafloor trawling.

  • This unexpected solution could save the world's depleting corals

    Underwater mooring buoys are proving pivotal in efforts to save corals along the Red Sea. In practice, the installed buoys are anchored to flat, solid bedrock provide a ready-made anchor for tourists arriving by sea, instead of letting them drop anchors on vulnerable underwater ecosystems. Since 1995, more than 1,400 buoys have been installed along the Red Sea coastlines.

  • A shellfish company gets into the weeds

    In their fight to protect eelgrass, The Swinomish Indian Tribal Community sued the Army Corps and the National Marine Fisheries Service. The Swinomish Tribe argued that creating wide exemptions to shellfish farming could endanger eelgrass, which they rely on. Their win led to stricter regulations that require individual permits rather than national permits. The tribe also opened its own shellfish operation.

  • Could crushed rocks absorb enough carbon to curb global warming?

    Scientists are testing if adding alkaline substances to seawater can allow oceans to absorb more carbon dioxide emissions. Early tests suggest this could be a potential way to combat climate change, but there are still many questions about how this can scale, how it impacts the natural ecosystem, and if it’s cost effective to implement.

  • Tidal energy could be huge – why isn't it?

    Tidal power is a form of renewable energy that is caused when wind turbines are placed on the sea floor. These powerful turbines harness the power of tides and could capture enough energy to power all the homes in the U.S. Tidal Range Plants have been installed in countries like France, South Korea, Canada, and China. Despite their power, they require a lot of money to install and have mostly been installed in wealthy countries in the Global North.

  • New York City Is Building a Wall of Oysters to Fend Off Floods

    From New York City to Texas, localities are using oysters to protect themselves from flooding. They are dropping oysters along the coast for baby oysters to grown on, ultimately leading to the creation of wall-like reefs. The oyster reefs mitigate the blow of big waves during hurricanes. A study showed that reef-protected areas dissipated waves and had 54% less erosion. Building oyster reefs form part of a larger movement known as "green infrastructure" to manage the effects of climate change, as opposed to building concrete infrastructure like sea walls and dikes.
