In Cornwall, and the wider UK, over 70% of the pla In Cornwall, and the wider UK, over 70% of the plastic found on our shores comes from lost or discarded fishing nets –  so called ‘ghost nets’. These nets persist for hundreds of years, still lethally effective at killing marine life, until they finally breakdown into insidious microplastics that infiltrate the food chain - causing unknowable harm.
🦑
Each of our Ghost Net Bracelets help our effort to fight the scourge of marine plastic. Each is hand made here in Looe Harbour, Cornwall and fund our efforts to convert lost ghost netting and other marine plastic that we have recovered from isolated coves and under the waves into cherished items people will never discard – ending its haunting of the ocean and exorcising Cornwall’s wild coast of  the danger this ghost fishing gear poses to wildlife.
🌊
Please support us and Cornwall’s coast by heading over to our website (link in the bio) and ordering one of our bracelets - each one represents kilos of netting removed from the worlds oceans.

We're proud to help local businesses in Looe to ph We're proud to help local businesses in Looe to phase out the sale of  plastic drop net crab-lines (which end up in the harbour) so far our long term partners at Mayflower Studio, The Schooner and Banjo Beach Shops have now has been joined by Jamie Pearn’s Cornish Gift shop,  Bray & Sons and The Guildhall Market in the phasing out of these troublesome items.
🌊
Local businesses have been working with Looe Marine Conservation Group and Behaviour Change Cornwall since 2017 -  and invested into new producers of plastic-free all natural crab lines with major importers @kandytoys made - that are finally made for a price low enough that they sell all around the UK - being all plastic free and coloured naturally these lines now pose less threat to wildlife or propellers in the harbour, rotting away to harmless drift wood overtime.
🌍
Looe Marine Conservation Group has worked for years now to create, pay for and install new recycling bins along the harbour - whilst we’ve teamed up to create behavioural signs and a crabbing code to tackle the plastic discarded into the sea by some visitors to this once-quaint now-heaving idyllic Cornish harbour so now we hope to phase out all plastic lines by 2022.

Life underwater faces a multitude of environmental Life underwater faces a multitude of environmental threats: but one is far more visible and virulent here in Cornwall than the rest, Plastic Pollution. In less than century since its creation, plastic in its myriad forms can be found in every marine environment: from lost or discarded fishing nets called ghosts nets threatening to entangle wildlife in the depths of the ocean; to microplastics mimicking sand grains on the beach.
🧠
Plastic isn’t ‘bad’ or ‘good’ – it is a both wonder material, strong, light and resistant (hence why it lasts) and without it we wouldn’t have a lot of things we rely on everyday. The problem occurs when its let loose into the wild where it continues to haunt us for a unknown number of centuries.
🦑
Don’t just take our word for it, here are the facts: of the staggering 6,300 million tonnes of plastic waste was generated between 1950-2015, 9% has been recycled, 12% incinerated and a whopping 79% has been disposed  in the natural environment. And despite increasing awareness, by 2050, this amount is only projected to increase.

Bleak, freezing, inhospitable: its hard to oversta Bleak, freezing, inhospitable: its hard to overstate how harsh Arctic climate is for a near-hairless ape from Africa. Hidden in darkness for half a year and blinded by 24 hour light for the other half - It was one of the last places humans settled. The Vikings who tried to live their failed and to this day few Europeans live there, only the native Inuit peoples have mastered this ice-scape.
🧊
Key to the Inuits' success was their sustainable hunting culture they developed over the centuries - as the fragile arctic ecosystem makes conservation of living resources essential to long term survival. Put simply there is so little there to eat you the only way to survive is to be careful how much you hunt, use all that you kill and keep moving.
🌊
This culture is changing. The Inuit are giving up a nomadic lifestyle due to the pressures and temptations of the modern world. The problem with this is the Inuits practices are sustainable only whilst the population remains low. This means settling down to enjoy the basic comforts we all enjoy in the UK - electricity, running water, heating and legal recognition that we have a right to be on the land we live on - could deplete the very resources the Inuit depend on, endangering their long term survival.
🌍
However, the impact of the people who live in the Arctic is tiny compared to the impact the rest of us are having.  We are indirectly driving a drastic and radical transformation in the furthest region of the planet. Mining, commercial fishing, toxic plastics, international  pollution and most-significantly climate change, which threatens to increase arctic sea temperatures, ocean acidity and leave the ocean devoid of summer ice cover, are already exacerbating an already fragile ocean environment. On top, as the ocean ice melts, it opens up the region to intrepid ships and explorer- creating a geopolitical scramble for the Arctic’s resources - with the Arctic poised to be the next Africa, divided and exploited with terrible results for those living there.
🐬
Luckily the Inuit are resilient - they've had to be - despite the perverse twist of fate that means they are harmed by the purchases of people thousands of miles away.
Man of War’s are a nesting doll of symbiotic rel Man of War’s are a nesting doll of symbiotic relationships - externally they harbours within their tentacles a symbiotic fish, called - rather unimaginatively -  the ‘Man-of-War Fish', that feeds from scraps of the Man-of-War’s food and eats part of the siphonophore's body! However, in return the fish acts as live bait to attract other fish. Other animals also use the Man of War for their own defence, Nudibranch Molluscs for example eat Man-of-Wars to use the Nematocysts in their own body to stop predators. 
🌊
The Man of War challenges simple ideas of what a organism is, giving rise to lots of questions which make us wonder whether any organism is truly separate from the rest of life.
🧠
Sadly the appearance of these marvellous wonders is less than marvellous - their continual reappearance on Cornwall's shores is a warning sign of the changes warming waters will have on our coastal ecosystems.

It turns out that corals prefer to eat microplasti It turns out that corals prefer to eat microplastics - tiny pieces of plastic pollution that are barely visible to the naked eye - rather than their natural food!
🦑
A study in 2017, trying to understand why and how microplastics are getting in the marine food chain, found that when coral were offered plastic, sand and bacteria-covered plastic + sand they actually preferred the naked-plastic. They even retained the plastic for longer compared to the other food.
🧠
They suspect that some types of plastic contain chemicals which stimulate the corals - which are tiny animals related to jellyfish - to feed. Or in other words, plastic is tasty for corals.
🐬
This could be because the hydrocarbons in oil that make up plastic mimic biological chemicals - we must remember all oil, & therefore plastic, originally was animals and plants aka fossil fuel. Finding out that corals find plastic tasty may seem rather abstract, but it helps scientists build up a better picture of how plastic is spreading through the marine environment - as corals are eaten by many other animals.
🦑
This shows that an understanding of both human and animal behaviour is required for successful conservation...

Here on #freathybeach - like the rest of #cornwall Here on #freathybeach - like the rest of #cornwall - you’ll find the insidious remains of ‘ghost netting’ - the lost nets of fishermen who have a dark second life ensnaring wildlife.
🦑
The exact effects of plastics depend on their size. Plastic is classified as either macro-plastics, which is plastic debris that is visible to the eye or as micro-plastics which are often impossible or difficult to see and are classified as under 5mm.
🧠
Because plastic is so resistant to deterioration, brightly-coloured mimicking food and often purposely shaped into nets to capture fish can damage a spectrum of marine creatures due to ingestion, entanglement and choking, which are documented in a range of marine mammals, seabirds, turtles, corals and fish.

🦑
The Man of War is not even a jellyfish as it appears, nor actually is it even a single ‘it’. These weird pasty shaped creatures wash up all over Cornwall now every winter (thanks to our warming seas). What are they then?
🐬
The Man-of-War is actually a siphonophore, a type of carnivorous colony made up of several individual animals. These individual entities are called zooids or polyps. The polyps/zooids work together, each with its own specialized role and separate nervous system.
🐠
They consist of: (i) A pasty shaped float sack (or more accuratly a gas bladder known as a Pneumatophore) allowing them to float along the surface, and also acting as a sail; (ii) Up to 90-165 foot long, stinging Nematocyst-covered tentacles (Dactylzooids) for killing small fish and other small prey; (iii) enzyme-secreting digesters (Gastrozooids), which digest their prey once the tentacles do their work ; (iv) and the reproductive Gonozooids, which make new baby Man of War's.
🐡
The Man of War begins as a single fertilised egg cell (like most animals) which splits into four separate different mutlicelluar ‘animals’, who on their own cannot survive. The weird co-existence of these combined parts  may be how all complex life (us and all other animals) began!

Imagine your legs, arms, gut and head all having a separate brain each and working together?!

Amazingly it has been less than century since the beginning of plastic production, yet plastic debris can be found in every marine environment, from bags in the depths of the ocean to potentially carcinogenic plastic micro-fibres floating in the air of city streets. Picking it up takes individual pieces out of the environment - but can’t be the solution alone

We live in a time of unprecedented change and unce We live in a time of unprecedented change and uncertainty - which makes it incredibly difficult to make decisions for the future, when the present is so demanding.
🧠
This long term discounting is always a feature of our psychology - we’ve always discounted future risks and placed more emphasis on present risks. Our ancient ancestors would see not much point worrying about storing food for winter when your dieing of hunger now - just as we worry less about pension payments than saving for house at 25.
🧠
The problem is the future has a horrible habit of becoming the present - as governments who prioritised economic growth over pandemic preparation are discovering in 2020. Only future generations will find out whether we can overcome our primordial minds to prioritise the environment they will inherit...
