Fixed coastal defenses have long been erected in many nations and coastal countries typically have a navy and some form of coast guard. Coasts, especially those with beaches and warm water, attract tourists.

In many island nations such as those of the Mediterranean, South Pacific and Caribbean, tourism is central to the economy. Coasts offer recreational activities such as swimmingfishingsurfingboatingand sunbathing.
Growth management can be a challenge for coastal local authorities who often struggle to provide the infrastructure required by new residents. Threats to a coast Coasts also face many human-induced environmental impacts. The human influence on climate change is thought to contribute to an accelerated trend in sea level rise which threatens coastal habitats.
Pollution can occur from a number of sources: Fishing has declined due to habitat degradationoverfishingtrawlingbycatch and climate change. Since the growth of global fishing enterprises after the s, intensive fishing has spread from a few concentrated areas to encompass nearly all fisheries.
The scraping of the ocean floor in bottom dragging is devastating to coralsponges and other long-lived species that do not recover quickly. This destruction alters the functioning of the ecosystem and can permanently alter species composition and biodiversity. Bycatchthe capture of unintended species in the course of fishing, is typically returned to the ocean only to die from injuries or exposure.
Bycatch represents about a quarter of all marine catch. In the case of shrimp capture, the bycatch is five times larger than the shrimp caught. It is believed that melting Arctic ice will cause sea levels to rise and flood coastal areas.
Marine pollution and Marine debris Conservation Extraordinary population growth in the 21st century has placed stress on the planet's ecosystems. For example, on Saint Luciaharvesting mangrove for timber and clearing for fishing reduced the mangrove forests, resulting in a loss of habitat and spawning grounds for marine life that was unique to the area.

These forests also helped to stabilize the coastline. Conservation efforts since the s have partially restored the ecosystem.
Types of coast According to one principle of classification, an emergent coastline is a coastline which has experienced a fall in sea level, because of either a global sea level change, or local uplift. Emergent coastlines are identifiable by the coastal landformswhich are above the high tide mark, such as raised beaches. In contrast, a submergent coastline is one where the sea level has risen, due to a global sea level change, local subsidenceor isostatic rebound.
Submergent coastlines are identifiable by their submerged, or "drowned" landforms, such as rias drowned valleys and fjords. Emergent coastline and Submergent coastline According to a second principle of classification, a concordant coastline is a coastline where bands of different rock types run parallel to the shore.
These rock types are usually of varying resistanceso the coastline forms distinctive landforms, such as coves. Discordant coastlines feature distinctive landforms because the rocks are eroded by ocean waves. The less resistant rocks erode faster, creating inlets or bay ; the more resistant rocks erode more slowly, remaining as headlands or outcroppings.
Concordant coastline and Discordant coastline Other coastal categories: As we climbed aboard our dive boat and took out across the water, I was filled with questions: What species need them to survive? Do they all contribute to the richness of this region? And then, as we approached an old shipwreck, I laid eyes on her. She was beautiful, with olive-green skin and dark spots over her body, her large round eyes stared back at me as our dive team slowly approached.
It reminded me of my youth in the Mediterranean Sea before large fish were wiped out, particularly, the large, beautiful groupers. Across the world, sensational tales of Goliath groupers stalking and attacking fisherman have been told throughout the centuries. As rulers of their home territories, goliath groupers are found in predictable places, around deep water shipwrecks, sink holes and natural ledges that provide them both protection and a place to ambush unsuspecting prey.
They also aggregate in huge numbers during certain times of the year to reproduce. This predictable pattern has gotten them into trouble. Jean-Michel Cousteau and the team explore mangroves forests to learn more about their vital role in keeping our oceans, and people, healthy.
Once listed as critically endangered, goliath groupers have been rebounding in recent years due to increased protection over the last two decades. They are immensely important habitat for juvenile fishes. As researchers learn more about the life cycle of groupers and other fishes, they are realizing the various life stages and the importance of particular habitats, like mangroves, in supporting new generations of fishes.
Because of the intricate branches and roots, mangroves provide the perfect sanctuary for young fishes and invertebrates like crabs and shrimps. Here, they are safe from bigger predators, and can hide and hunt among the complex branching structures of the mangrove roots.Where The Atlantic Ocean And The Caribbean Sea Meet Is Stunningly Breathtaking
For Goliath groupers, juveniles will spend the first five to six years of their lives living among these tangled undersea nurseries. In South Florida alone, it is estimated that up to 90 percent of commercially valuable sea life depends on the mangrove forests for some stage of their life cycle.

Along the edge of the sea, they can form dense aggregations, turning shorelines into forests. To survive this harsh environment, mangroves have special adaptations, including filtration systems that keep salt out and complex roots that anchor mangroves upright in shifting sediments. Their complex root structures help trap and recycle nutrients, as well as filter toxins from the water. Particularly important for us, mangrove forests are responsible for keeping our shorelines intact.
They act as buffers, protecting the coastline from erosion due to major storms and hurricanes. And up in the treetops, mangroves provide nesting grounds for hundreds of bird species like brown pelicans, magnificent frigate birds and roseate spoonbills.
