Chile has created a vast marine park around the Desventuradas Islands, a few hundred miles off its coast, to protect many species that can be found nowhere else in the world. "For many years, Chile has been one of the most important fishing countries in the world," said campaigner Alex Munoz. With the marine park's creation, he added, "we're also becoming a leader in marine conservation." 

Plastic waste causes $13 billion in annual financial damage to marine ecosystems, though the actual cost of plastic waste to the overall environment may be much higher, according to two reports released at a meeting of the United Nations Environment Assembly. One report, the UN Environment Programme Year Book, notes that when plastic material fouls fishing equipment and pollutes beaches it threatens tourism, fisheries and businesses in addition to marine life.

The new Tun Mustapha marine park & shark sanctuary in Borneo is the biggest marine protected area in Malaysia

Britain has created the world's largest marine reserve, covering about 322,000 square miles of the South Pacific around the Pitcairn Islands. The move is an attempt to clamp down on illegal fishing. "People know Pitcairn because of the Mutiny on the Bounty, but their real bounty is the rich marine life underwater," said National Geographic explorer Enric Sala

Unhappy with how regional authorities have failed to protect fish stocks in the Western Pacific, Palau has launched its own bold initiatives - creating a vast marine sanctuary and conducting an experiment designed to reduce bycatch in its once-thriving tuna fishery.

President Barack Obama today announced a major expansion of the Pacific Remote Islands Marine National Monument, rendering large areas of the central Pacific off-limits to fishing and energy exploration. The move will expand the marine sanctuary to more than 780,000 square miles.

The Marine Stewardship Council (MSC) has released a new report highlighting the positive impact certification can have in delivering the Sustainable Development Goals (SDGs). The MSC Global Impacts Report 2017 details more than a thousand examples of positive change being made by certified fisheries to safeguard fish stocks and marine habitats.

Pacific Northwest shellfish producers are the first harbingers of a trend that may have wide ranging implications for the broader fishing industry: ocean acidification. By proactively seeking out adaptation solutions early on, the Northwest shellfish industry is attempting a self-rescue that may provide important lessons as other commercial species begin feeling the impacts of increasing acidification.

The approval by the government of Chile of the largest Marine Protected Area (MPA) in continental Chile is a boost to conservation efforts for blue whales and dolphins

Machine washing of clothes is a major contributor to plastic pollution in the oceans. Every time we do laundry, garments made from synthetic fabrics such as fleece and polyester shed small plastic fibers that end up in the water and pollute rivers and oceans. So denim giant G-Star and marine pollution campaign group the Plastic Soup Foundation are joining forces to stop this process in its tracks with a battle against microfiber.

As a new Greenpeace report details, seafood supply chains are still far from transparent, despite increasing adoption of well-known sustainability certifications like the Marine Stewardship Council (MSC).

Just a day after a group of cross-party MPs called on the UK government to ban microbeads, Greenpeace released a report outlining the science on the impact of microplastics, including microbeads, on oceans and seafood. The non-profit is also urging the UK government to ban microbeads, "both due to the damage they cause to marine life and as a precautionary measure against the risk of human consumption."

n what has been hailed as a far-reaching victory for global shark conservation, Air China has become the first airline in mainland China to ban shark fin cargo on its flights. The airline, which is headquartered in Beijing, announced the ban on Friday. "We were one of the first airlines in China to raise the awareness of the unsustainability of the global shark trade," says a message on the carrier's website. "We understand the community's desire to promote responsible and sustainable marine sourcing practices, and this remains important to Air China Cargo's overall sustainable development goals."

The growing acidity of the oceans as they absorb ever more carbon dioxide, a factor exacerbated in the winter, raises concerns for the most basic marine life. An Antarctic study of the bottom of the ocean's food chain involves a mooring as tall as the Empire State Building submerged at 1,600 feet and equipped with sensors recording temperature, dissolved carbon dioxide, salinity and pH.

Global trade has made it easier to buy things. But our consumption habits often fuel threats to biodiversity - such as deforestation, overhunting and overfishing - thousands of miles away. Now, scientists have mapped how major consuming countries drive threats to endangered species elsewhere. Such maps could be useful for finding the most efficient ways to protect critical areas important for biodiversity, the researchers suggest in a new study published in Nature Ecology & Evolution. For example, the maps show that commodities used in the United States and the European Union exert several threats on marine species in Southeast Asia, mainly due to overfishing, pollution and aquaculture. The U.S. also exerts pressure on hotspots off the Caribbean coast of Costa Rica and Nicaragua, and at the mouth of the Orinoco around Trinidad and Tobago. European Union's impacts extend to the islands around Madagascar: Réunion, Mauritius and the Seychelles. The maps also revealed some unexpected linkages. For instance, the impact of U.S. consumption in Brazil appears to be much greater in southern Brazil (in the Brazilian Highlands where agriculture and grazing are extensive) than inside the Amazon basin, which receives a larger chunk of the attention. The U.S. also has high biodiversity footprint in southern Spain and Portugal, due to their impacts on threatened fish and bird species. These countries are rarely perceived as threat hotspots.

But climate change is making it harder for resort owners and tour operators to make good on this promise. Climate change is having more of an impact on tourist destinations by eroding beaches and bleaching coral reefs. Mountain destinations are not immune either, as a warming climate melts glaciers and snow pack. The latest bleaching of the Great Barrier Reef has again brought to the forefront the growing impact of climate change on tourist destinations. According to the Great Barrier Reef Marine Park Authority, warmer than usual waters have caused bleaching (PDF) along much of the reef, and have killed nearly a quarter of its coral.

Mislabeled seafood products have become a widespread problem: Recent studies have found that 30 percent of seafood products are mislabelled and that such errors have led to significant distrust in labels among consumers. Meanwhile, DNA test results have reinforced that the Marine Stewardship Council's (MSC's) ecolabel provides credible traceability.

Recent studies have shown, for example that the loss of important predators - from wolves in boreal forests to sharks in seagrass meadows - can lead to growing populations of terrestrial and marine herbivores, whose widespread grazing reduces the ability of ecosystems to absorb carbon.

Carnival, docked in the spotlight when it received the New Economy's Clean Tech Award for Best Marine Solutions Company. The award recognized Carnival's decision to install a new exhaust filtration system on its North American ships, at an estimated cost of $180m

The Volkswagen Group has joined the Clean Shipping Network, an association of cargo owners, and will use the Clean Shipping Index (CSI) assessment tool to analyze and reduce the environmental impact of marine shipment.
