Eelgrasses covered with small snails, which keep the leaves clean by feeding on algae that live on them.
Healthy seagrasses form underwater meadows teeming with fish and shellfish. A successful large-scale restoration project in Virginia could become a model for reseeding damaged seagrass beds worldwide.
Sea levels could be two metres higher by 2100. How will our relationship to the drowned coast change?

Empatheatre's latest production is more than a play about three characters who live near the sea. It's a model for collective consultation on how to save the ocean.
Mangroves along Mexico’s Yucatan coastline.
A new study estimates that mangroves prevent over $65 billion in damage from coastal storms every year, and says mangrove protection should be funded in the same way as infrastructure like seawalls.

Bangladesh is on the front lines of climate change, but factors including money, gender and religion make some Bangladeshis much more vulnerable than others. Can it find inclusive ways to cope?
The San Pedro Mezquital River is the last free-flowing river in Mexico’s western Sierra Madre.
Thousands of hydropower dams are under construction around the world. New research shows that by cutting off sediment flow, these dams can have big ecological effects on far-off bays and deltas.
Phragmites, an invasive species, line this marsh at Sachuest Point in Middletown, Rhode island.
Phragmites australis, an invasive reed, has taken over wetlands across the US. But it also stabilizes shorelines and harbors many fish and birds. Is it time to compromise with this alien?
Carbon storage in Australian mangroves can help mitigate climate change.
One surprising potential benefit of sea-level rise is it helps coastal wetlands store more carbon.
Wetlands are feeding, nesting and breeding sites for migratory birds, such as these sandhill cranes in Minnesota.
The Trump administration is sharply reducing environmental protection for wetlands and streams across the US. This roundup of stories spotlights the many benefits that such water bodies provide.
Mangrove forest in Pichavaram, Tamil Nadu, India.
Mangrove forests along the world's tropical and subtropical coasts store enormous quantities of 'blue' carbon – especially in river delta zones, where soil builds up quickly.
How much should a council pay to protect private beachfront properties?
How far will we go to protect high-risk beachfront property? New research suggests local councils are too willing to spend public money to protect private landowners from coastal climate change.
Cumberland Island National Seashore off the coast of Georgia.
How do the narrow ribbons of sand that line the Atlantic and Gulf coasts withstand the force of hurricanes? The answer lies in their shape-shifting abilities.
Waves lap against the shore on the south coast of England and the North coast of France – but the answer to this puzzle is in the wind and the land, not the waves themselves.
St Agnes, Cornwall.
If we know what makes species tick, we can start truly understanding life on the UK's coast.
Little Missouri River, North Dakota.
Recent research shows that US rivers are becoming saltier and more alkaline. Salt pollution threatens drinking water supplies and freshwater ecosystems, but there is no broad system for regulating it.
Mangroves in the Florida Everglades.
As Earth's climate warms, mangroves are expanding north and south from tropical zones. Mangroves reinforce shorelines and store huge quantities of carbon, so protecting them is an effective climate strategy.
Coastal municipalities need to prepare for higher chances of storms and rising sea levels.

A climate scientist explains how New Hampshire managed to overcome the political divide to make real progress on climate change.
Australia’s coastline has moved before thanks to changes in sea level.

People have been forced to move in the past thanks to changes in sea levels that affected Australia's coastline.
Dooagh beach, Ireland.
A entire beach in Ireland has returned 33 years after being washed away.
Early in the morning and late in the evening is when shorebirds escape disturbance on the beaches on which their survival depends.
We aren’t just jostling with each other for beach space. Scuttling, waddling, hopping or flying away from beachgoers all around Australia, wildlife struggles to survive the daily disturbances.
