Chemical pollution and hunting pushed Ospreys to the edge of extinction in the mid-20th century. Today, they have rebounded and can be spotted worldwide, often nesting on manmade structures.

Marshes, swamps and other kinds of wetlands provide valuable services, such as effective natural flood control. But they are being destroyed for development in many parts of the world.
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.
Coastal development is destroying marshes, mangroves and other wetlands that provide valuable protection from hurricanes and storms. Research shows these benefits can be worth millions of dollars.
Hurricanes frequently move inland in the southeast US, causing widespread river flooding, but emergency plans focus on protecting people in coastal communities.
Widespread flooding in North Carolina from Hurricane Florence shows the need for better advance planning in inland areas of the south and mid-Atlantic, especially near rivers.
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.
Many US coastal towns are building defenses to protect against rising seas and storms. This can encourage people to stay in place when they should be moving inland.
For 50 years California has used laws and policies to manage development along its 1,100-mile coastline and preserve public access to the shore. Climate change will make that task harder.
Conflicts over coastal areas have largely been between development and preserving what makes these attractive places to live. Rising sea levels are now complicating our relationship with the coast.
As Atlantic hurricane season opens on June 1, eastern U.S. cities can prepare by updating laws, codes and ordinances that hamper rebuilding after storms.
Many properties are at risk from rising sea levels, with owners and councils at odds over the costs of defending these. NSW law reform may lead to more forward-looking climate change adaptation.
Coastal communities include 24 federal seats held by margins of 5% or less, and their local councils are pressing the Australian government to show more urgency about the impacts of climate change.
Managing the impacts of rising seas for some communities is being made more difficult by the actions of governments, homeowners – and even some well-intentioned climate adaptation experts.
The coast alongside the Great Barrier Reef is home to ports, farms, holiday resorts, and more than a million people. It all puts pressure on the Reef, and it's time for some firms plans to manage it.
Port traffic near the Great Barrier Reef will more than double by 2025, as coal and other exports grow. While major incidents are rare, the chronic toll on the reef itself still remains largely unknown.
The government says it has met all of the recommendations for safeguarding the Great Barrier Reef. But a close reading of the dozens of UN recommendations shows that many have been only partly fulfilled.
Urban sprawl has spread to the sea, as more and more man-made structures are being built along the world's coastlines. Just as we do on land, we need to think about how to build sustainably at sea.
