Les multiples fonctions de la Posidonie

The multiple functions of Posidonia

The Mediterranean Posidonia ( Posidonia oceanica ) is endemic to the Mediterranean Sea and the most common seagrass species in these waters. It covers between 25,000 and 50,000 km2 of coastal areas, corresponding to 25% of the seabed at a depth of between 0 and 40 m. Posidonia plays a key role for marine life but also for the preservation of our beaches, where we wear our ethical swimsuits .

Des filets de pêches usagés pour aller surfer et faire du bien aux océans

Used fishing nets to go surfing and do good to the oceans

Nomads Surfing presents the first surf fins made in France from fishing nets abandoned at sea or collected in ports from fishermen and recycled.

Created in 2017, Nomads Surfing, a young company from Bordeaux, offers surfers an eco-responsible alternative with eco-designed surf boards and accessories.

The story begins one evening in April 2017, at the foot of the Pyla dune facing the ocean.

Three friends, Basile, Nicolas and Thomas, surfing enthusiasts and globetrotters, make a terrible observation: plastic is constantly destroying our ecosystem. They have had the sad experience of the rubbish beaches of Kuta in Bali with the winter waste on the Aquitaine coast and decide to act, on their own scale, to preserve the environment and the oceans while continuing to surf.

The booming surfing industry is a polluting industry due to the materials used for the practice (surfboards, wetsuits) and the attraction of traveling to the other side of the world in search of the wave. perfect.

Nomads Surfing was born, with the aim of offering an alternative to surfers wishing to minimize their impact on the environment and to change mentalities around practice and eco-responsibility.

Responsible products with a reduced carbon footprint

Based in Bordeaux but with rich Malaysian and Filipino influences – hence the name of the brand – Nomads Surfing has created surfboards labeled “eco-board” by an independent certification body. These surfboards are made from partially recycled polystyrene foam blocks and from an epoxy resin made up of 40% plant waste or natural flax and basalt fibres. If the boards are not yet 100% ecological, their impact on the environment is less compared to the vast majority of boards on the market since they are also shaped in Portugal in Europe and not in Asia.

The boards are sold online at nomads-surfing.com , starting at €590.

The first drifts from recycled fishing nets, Made in France

For a few months, Nomads Surfing has been offering the first fins – fins under the surfboard – made from recycled fishing nets. The nets, recovered in Spain, are transformed into nylon balls and injected into a drift in a workshop in Thiers (63).

A commitment to the future

Nomads Surfing has made the fight against climate change its priority. This translates into choices on materials, transport, packaging... Nomads Surfing is:

• Responsible and local production, in Portugal and France

• Alternative materials: cork, bio-sourced resin, flax fiber and basalt…

• A commitment to the social and solidarity economy by working with the local associative fabric

• Waste recovery: bringing products back to life at the end of their cycle and limiting waste production as much as possible.

• Responsible logistics with the use of reusable packages Protecting the oceans also means thinking about future generations. Nomads Surfing supports 3 associations in Malaysia, the Philippines and France who have made the protection of the coast and the oceans their first fight, by donating 5% of sales to them in order to help their projects to protect the planet.

Les menaces de la Posidonie

The threats of Posidonia

Posidonia (Posidonia oceanica) is a flowering plant endemic to the Mediterranean that provides multiple ecosystem services. It forms vast meadows between the surface and 40 m deep. Thanks to Posidonia, we have transparent waters and white sand beaches where we can enjoy our pretty ethical swimsuits. It supports biodiversity and acts as a fish nursery. It prevents coastal erosion, produces oxygen and is a crucial carbon sink absorbing 7% of the islands' total carbon emissions. However, this ecological treasure is now in danger, through the action of man.

Posidonia threatened by pollution

In addition to providing important habitat for a wide variety of marine species, Posidonia plays a role in protecting our planet from the increasing buildup of carbon dioxide. It acts as a " carbon sink ", like terrestrial plants, by absorbing carbon dioxide from the atmosphere and thus helping to slow the effects of global warming .

Like tropical forests, seagrass meadows are threatened by the insatiable human need to expand, build and consume. These aquatic plants are increasingly being directly destroyed by trawler fishing, fish farming, the construction of new marinas and seaside resorts and the anchoring of pleasure boats. However, the greatest threat comes from land-based sources of pollution and in particular from nutrient loading in the sea (which corresponds to the release into the environment, by human activities, of nitrogen, phosphorus and other elements nutrients).

Scientists have found that nutrient loading is responsible for the deterioration of Posidonia. Nitrogen and phosphorus find their way into the sea from urban sewers, industrial outlets, agricultural areas, atmospheric deposition from agriculture, and the burning of fossil fuels. Nitrogen and phosphorus are the most important nutrients for regulating the growth of planktonic algae, and therefore the transparency of the water and the lighting conditions of Posidonia. But too much of these elements is detrimental to the aquatic flora, and will make your swims in a sustainable swimsuit less pleasant!

The different threats of Posidonia

Posidonia grows very slowly; about 1 to 5 centimeters per year. For this reason, the damage caused by a one-day anchor could take decades to be restored. In 2017, researchers estimated that the anchor of a 15m-long boat uprooted about 165 Posidonia shoots in Portocolom; and that it would take 5 years of optimal conditions to regenerate them. This single action released 915g of carbon into the atmosphere, adding to climate change. And this is just one example of the damage that a single unconscious act of anchoring on seagrass beds can cause.

Project this into the rest of the Balearic Islands and you will soon realize that action is needed without further ado. A study revealed that the Posidonia meadows in S'Espalmador (Formentera) were reduced by 44% between 2008 and 2012, mainly due to the impact of the anchoring of boats. And then, a few years ago, there was the documented event of the 116 meter Turama boat in Formentera whose damage will take almost a thousand years to repair.

In addition to uprooting the plant, anchoring and boat activity also increases water turbidity (its ability to scatter or absorb incident light), making it harder for the plant to access light. it needs to photosynthesize and survive. This is why poorly treated water is another of the main threats to Posidonia meadows. Unfortunately, there are still several Posidonia bays and meadows in Mallorca that suffer from the impacts of poor water quality. Action is also needed and urgent to resolve this problem.

The third major impact on Posidonia is climate change . Warmer waters increase Posidonia mortality. Indeed, if anchors and sewage weaken the plants, the Posidonia meadows are more vulnerable and less able to cope with climate change. The protection and recovery of seagrasses is therefore more essential than ever, because they are our underwater forests. It is therefore important that everyone leads the fight to preserve the environment at their own level, starting for example by buying an eco-responsible swimsuit for the beach.

L'océan devient de plus en plus acide

The ocean is getting more and more acidic

Due to carbon emissions, the ocean is changing, which endangers a whole series of marine organisms. Acidification is a consequence of climate change; a slow but exorable real-life experiment in which industrial emissions of carbon dioxide into the atmosphere are absorbed and then undergo chemical reactions in the sea. Rising ocean acidity has already bleached Florida's coral reefs and killed many precious oysters in the Pacific Northwest.

Marine life threatened by rising ocean acidity

Grace Saba is an assistant professor of marine ecology at Rutgers University, where she studies how fish, clams and other creatures respond to increasing levels of ocean acidity. Now scientists like Saba want to know what could happen to the animals that live in the northeast, a region home to commercially important fish, wild stocks of clams and scallops that cannot escape growing acidic waters.

Scientists say the pH level of the world's seas has already dropped - on average from 8.2 to 8.1 on the pH scale (lower numbers are more acidic). This represents a 26% decline over the last century (because the pH scale is logarithmic). But as the ocean absorbs more industrial carbon dioxide emissions, its pH is expected to double to 7.7 pH units by the end of the century, according to Aleck Wang , professor of marine chemistry at the Woods Hole Oceanographic Institution . . Which is very bad news for all those who wish to enjoy the beaches for a long time to come in their ethical swimsuits.

By killing crucial organisms like corals, oysters and many plankton, acidic waters can upset the food chain of the oceans. Fishermen in the Gulf of Maine are already seeing seasonal changes in ocean acidity that could one day threaten a seafood harvest worth more than $600 million to Maine's economy. Further south in the mid-Atlantic region, seafood fishermen are also worried about their future.

"We're all trying to figure out the right way forward," said AJ Erskine , owner of a commercial oyster hatchery on Virginia's Potomac River. “I don't know if there is a solution, but the more data we have, the more knowledge we have. If we don't know the pH, how can we deal with it?”. Erskine is part of a group of fishermen, scientists, and state fisheries managers, called the Mid-Atlantic Coastal Acidification Network , which is pushing for more research and attention on the issue. As we also draw your attention to the choice of sustainable swimwear to contribute to the preservation of the environment.

Scientists are mobilizing

Scientists from the University of Delaware and NOAA (the United States Oceanic and Atmospheric Observation Agency) have just deployed the first permanent buoy to measure carbon dioxide levels in the Chesapeake Bay, the largest estuary in eastern United States. The moored buoy will help researchers determine if the bay can handle more CO2 from the atmosphere while combating human-caused pollution through surrounding farms and factories.

In another attempt to study acidification, researchers from the National Oceanic and Atmospheric Administration launched 7-meter-long, sail-powered surface drones across the Pacific and Arctic oceans to collect data on wind, temperature, and acidity.

L'association 5 Minute Beach Cleanup

The 5 Minute Beach Cleanup Association

What a great way to start or end your day at the beach, with your cute eco-friendly swimsuit, than to take a few minutes to pick up trash left on the sand. If we all spent even 5 minutes cleaning every time we enjoy our beaches, the collective impact would be immeasurable. This is precisely the mission that Carolina Sevilla has given herself through her association 5 Minute Beach Cleanup .

The challenge of Carolina Sevilla

The global plastic pollution crisis is universal. Never in history has there been a greater environmental problem with evidence so obvious that everyone can see it. While there are many positive initiatives underway, the damage of the past 60 years since mass manufacturing of plastic began is so great that we are only at the beginning of our chances of limiting the long-term damage to our planet and humanity.

In a past life, Carolina was a diplomat in New York before realizing her destiny lay in her home in Costa Rica, helping clean up the ocean and its surroundings one piece of plastic at a time. Today, Carolina lives the simplest life in a small cabin on the beach in Costa Rica. A hut which itself says is "a gift of nature" as it was built from a large tree that fell on the beach during a storm.

After being discouraged by how little she could achieve on her own, she set up " 5-minute beach clean up " as a hashtag and profile on Instagram in an attempt to stimulate interest in a wider audience for environmental issues.

The solution to clean our beaches

Carolina created the @5minutebeachcleanup Instagram profile as a simple challenge for everyone everywhere, summed up in this question: "Would you be willing to sacrifice 5 minutes of your beach time to pick up trash?"

On her News Feed, Carolina invites her growing number of followers to tag their own cleaning photos. To date, the account has garnered over 65,000 followers, inspired thousands to perform their own 5-Minute Cleanses, and brought Caroline global media attention.

Carolina is now working with Bionic Yarn BIONIC®, a materials engineering company that provides consumer and industrial markets with fully traceable, high-quality textiles made from recycled coastal and marine plastic. A textile used in particular to make alluring ethical swimsuits.

Carolina thinks it's the younger generation who can have the biggest impact because they have a different mentality. "I think happiness is that feeling we all have when you are aware of something and also want to share it. It's what we call 'Pura Vida' in Costa Rica (pure life)." , she says.

What impact for 5 minutes of cleaning?

Although 5 minutes may not seem like a lot to clean all the dirt from the beaches, every little detail counts. Which is, of course, the essential point of the association 5-minute beach clean up. When more people get involved, those same 5 minutes become hours, days and even weeks. Imagine how much dirt can be removed from beaches in that time if we share responsibility locally.

It can also be a great opportunity to teach children, family members, friends, colleagues, etc. the importance of oceans, beaches, marine life and their connection to us. Also, don't forget to opt for a durable swimsuit for your beach outings!

Les dangers de la pollution engendrée par le transport maritime

The dangers of pollution caused by maritime transport

More than 90% of the products in world trade are transported across the world's oceans by some 90,000 ships . Like all modes of transport using fossil fuels, these ships produce carbon dioxide which contributes significantly to global climate change and ocean acidification. But it's not just the carbon dioxide these ships release, a handful of other pollutants they generate also contribute to the problem.

Eco-responsible swimsuit

Marine Industry Toxic Gas Emissions

Shipping is responsible for a significant proportion of the global problem of climate change. More than 3% of global carbon dioxide emissions can be attributed to ocean-going ships. This is a proportion comparable to that of major carbon-emitting countries, and the industry continues to grow rapidly.

In fact, if global shipping were a country, it would be the sixth largest producer of greenhouse gas emissions . Only the United States, China, Russia, India and Japan emit more carbon dioxide than the world's maritime fleet. According to a study by the International Maritime Organization (IMO) on greenhouse gases (GHGs) dating from 2014, maritime transport emits around 940 million tonnes of CO2 per year and is responsible for around 2.5% of global greenhouse gas emissions. Enough to make your bathing in an ethical swimsuit much less pleasant!

Additionally, there is another huge environmental problem caused by the shipping industry: the amount of dangerous sulfur dioxide (SO2) emitted by ships as they travel from port to port across the world's oceans. Due to industry's use of higher sulfur, cheaper and lower quality fuel oil, shipping accounts for 13% of all SO2 emissions , for only 5% of global demand for oil it represents.

Other forms of pollution caused by maritime transport

It is not just the air that is polluted by the many ships sailing across the oceans. The maritime industry is also the source of other forms of pollution that affect the seas, marine life, and indirectly all those who would like to quietly enjoy their eco-responsible swimsuit in a healthy environment.

Oil pollution

Oil pollution from the shipping industry is considered to be the main reason for the increase in the level of marine pollution. Oil discharged from ships contains dangerous levels of sulphur, heavy metals and other harmful substances. Bilge oil from ships mixes with ocean water, causing severe marine pollution. A faulty engine and poorly done repair work are two potential causes of oil leaks in ships. Ship collisions and accidents also cause oil pollution.

chemical pollution

The release of chemicals from ships into the oceans is another threat that shipping poses to the marine ecosystem. Ships emit toxic chemicals from batteries, dry and industrial cleaning products, chemicals for daily operations, etc., which result in pollution of the waters in which these ships travel, and in which we bathe with our ethical swimsuits . Environmentalists argue that these chemicals pose a huge threat to the lives of sea creatures and life forms.

Ballast water pollution

Large ships use a huge amount of ballast water to stabilize themselves while moving. As these ships travel long distances, ballast water is often filled in one region and discharged to another whenever necessary. The problem is that this ballast water contains microbes and microorganisms in addition to vegetation and other marine animals. Thus, pollution is mainly caused by the displacement of local species and the disturbance of marine life. While vacationers enjoy the sun and their eco-responsible swimsuits on cruise ships, the marine life below suffers from this ballast water pollution. A very good example of such ecological damage is the huge increase in the population of jellyfish in the Black Sea.

The MARPOL Convention to combat pollution from ships

Marine pollution, whether from toxic gases, oil, chemicals, garbage, sewage or food waste that is dumped into the water, is a serious problem that affects the oceans and marine life. In an attempt to curb the problem, the international community has established the International Convention for the Prevention of Marine Pollution from Ships , also known as the MARPOL Convention , which is the main international treaty for the management of waste from ships. ships. For your part, participate in the ecological effort by opting for ethical and eco-responsible swimsuits .

Les types de tortues en Méditérrannée

Types of turtles in the Mediterranean

Fishermen and bathers in pretty ethical swimsuits are not the only ones to appreciate the Mediterranean. The Mediterranean Sea is also frequented by three species of sea turtles, two of which nest there and once harbored abundant populations: the loggerhead (Caretta caretta) and the green sea turtle (Chelonia mydas) . The leatherback turtle (Dermochelys coriacea) is a rarer visitor.

Loggerhead sea turtle

Eco-responsible swimsuit

The most common species in the Mediterranean is the loggerhead turtle (Caretta caretta). It was named after its large head equipped with strong jaws allowing the animal to break the hard shells of bivalves and crustaceans. Its nesting sites are located in tropical and subtropical regions, but it also inhabits temperate regions. Hatchlings are about 25mm long, while adults can be up to 100cm long and weigh up to 200kg. The nesting beaches in the Mediterranean are mainly located in the eastern part, especially in Greece, Turkey and Cyprus (where sustainable swimwear is highly valued). Most turtles inhabiting the Adriatic come from nesting beaches in Greece, especially the island of Zakynthos.

Loggerhead sea turtles live to be 60 years old and mature at 15 to 20 years old. The females return to the sandy beach where they were born to lay between 80 and 120 eggs in a nest. Loggerheads lay three or four nests each season, but only every three or four years. A female will return to the sea if disturbed during spawning. The incubation time of eggs until hatching is 55-60 days.

The green turtle

Eco-responsible swimsuit

The green sea turtle (Chelonia mydas) was named after its green fatty tissue responsible for the general appearance of the animal. It can reach up to 120 cm in length. Developing juveniles feed on invertebrates such as jellyfish and become herbivorous when they reach sexual maturity, feeding on algae and seagrass. This happens between the ages of 20 and 40. This is a very widespread species. Nesting sites are located in the tropics, but turtles can also be found in temperate waters.

In the Mediterranean, the green turtle is reported in low numbers (since 1830) but, as it can be confused with the loggerhead turtle, its presence is likely to be underestimated. The green sea turtle is listed as an endangered species . The Mediterranean population is the smallest and most threatened of all. Nesting beaches are located mainly in Cyprus and Turkey, but there are also some in Lebanon, Egypt and Israel. You could meet some in these places when you walk on the beach in your eco-responsible swimsuit.

leatherback turtle

Eco-responsible swimsuit

The leatherback turtle (Dermochelys coriacea) is the largest species of sea turtle with a shell up to two meters long. It can dive up to 1,000 m deep, more than any other turtle! It is easily distinguished by the absence of a bony shell, characteristic of other species of sea turtles. The skin-covered shell allows it to withstand high water pressure. The leatherback turtle is the most common species of sea turtle. It is found at sea, from Alaska in the north to the Cape of Good Hope in the south.

Despite its wide distribution, the leatherback sea turtle appears to be rather rare, with only 30 individuals recorded across the Adriatic since 1894. It is the only Mediterranean sea turtle species without any nesting sites in the basin. Adult animals can be over 180cm long and weigh 500kg or more. They feed on gelatinous zooplankton, such as jellyfish and salps, throughout their lives.
