Dumping our waste at Sea

Published

on

No matter where you are in the world, if you are into diving then it is always a great pleasure to get wet and look for wildlife or perhaps a new wreck. But sometimes the whole experience can be ruined by other people’s garbage. You can see it floating on the surface or just hanging in mid water trying to decide whether to up or go down. And there on the sea bed is more rubbish. Tyres, car batteries, prams, plastic in all shapes and sizes… the list goes on. Occasionally you put what you can in your pocket and bring it up for disposal into a convenient bin. Most times it just gets left there to become a permanent fixture of the environment or worse, becomes entwined into the food chain. Often we see animals that are caught up in garbage or have rusty fishing hooks caught in their bodies.

Do you ever wish someone would clear it all up? Well, there is a man who went a step further than just wishing. His name is Captain Donald Voss, he’s based on the east coast of Florida and runs the Marine Cleanup Initiative Inc., operating through funding from organizations such as NOAA, South Florida Water Management District, West Marine, Sebastian Inlet District and FPAT.

Jeff: I wrote to Don and asked him exactly what it was he did. 

Don:  We use volunteers to address the massive issue of marine debris, dumping, littering and just plain conservation of our natural resources for the use and entertainment of future generations. For water-based operations, we have a database of 400+ volunteers with boats, time and/or diving equipment who give of themselves to remove this mess.  For land-based operations, we have a growing core group of about 150 kayakers and SUP’ers who come out and swarm the islands and our boats assist them with the removal and transporting of the debris.  Our volunteers do this because I have asked them to help and we throw a pretty cool party afterward to thank them. Many of our crew are formerly Navy SEALS and just old divers who find a sense of accomplishment from giving back. Younger people like the enthusiasm I offer.  Most come because our group is allowed to dive places no diver has been since the ’70’s.  I point out you get to second base with nature when you dive our cleanup events.  I view myself as sort of a Pied Piper.

Jeff: Why do you do this?

Don:  In 1969, I was blown up in Vietnam and told I would lose my legs.  A few days later, the doctors decided my legs were of no harm to my survival and set the broken bones.  After a year of traction and rest, I was released and sent home to decide if I was going to be a crutches guy or a wheelchair guy. About the same time, a horse broke his leg in the Kentucky Derby.  Rather than shoot him, they tried a new technique of placing the horse in a sling into a pool and allow him to swim and mend his leg, gravity-free and then release him out to stud.  Upon hearing this, I decided this was exactly what I wanted…. to be placed out as a stud :).  I moved to the Florida Keys and began swimming, then snorkelling and finally diving.  I regained my strength and now I walk and dive and do all things with little restrictions from my 100% disability.  I firmly believe I owe my life to the water and I therefore use this platform pay-back.  I left the keys and returned to Ohio where I raised my kids and ran a huge not-for-profit recycling centre and also travelled the world diving. It did not matter where I was, I was always picking up debris and bringing it back to the boat for proper disposal.  I now have over 14,000 dives.  Eventually, when I retired and moved to Ft Pierce, I was asked to use my underwater photographic skills to determine if there was debris in the Sebastian Inlet.  I went in and looked around and formed this company.  The rest is history.

Jeff: How long have you been doing this?

Don:  I have been a conservationist and environmentalist my whole life. We formed our debris removal project in June of 2001 and used several base groups as sponsors for the first 3 years, but the in-fighting and greed caused them to split up. We, the divers that actually did the work, split free and formed what is now MCII.  So, we say 12 years.

Jeff:  Obviously you have noticed a change in the local environment where you have been cleaning up, but have you noticed any change in local attitudes to the disposal of waste?

Don:  It took until 2008 for the locals to really sit up and take notice. Up until then, we just operated in the Sebastian Inlet where we had received permission to dive. For those early years, people threw bottles at us while we dove and cursed us thinking we were stealing lobsters.  We were able to muster local news crews, marine patrols and fire rescue units to assist and used our efforts as a mock training and rescue session and these events melded well together.  We were crushed by three hurricanes in 2004 and 2005 and besides the overwhelming set back this caused, this really opened things up.  FEMA and governmental agencies were all over the area and minds opened.  There were (are) over 200 missing boats, several missing marinas and loads of missing houses and garages.  I was lucky enough to gain favour with many mayors, especially Bob Benton of Ft Pierce and some high ranking officials of FEMA and this allowed much needed exposure.  In 2009, assisted by a super smart Board member we applied for a NOAA Marine Debris and Habitat Restoration grant and received the only diver-driven grant of the 8 selected that year. With that first $200,000, MCII, has expanded and operates 200 days a year (+/- weather permitting) covering all the waters, inlets, islands and shoreline in a 90+ mile area covering four counties. We have parlayed our first grant and received numerous others, boosting our equipment, supplies, and public outreach to this larger area.  For our efforts, Loggerhead Marine Life Centre’s Blue Friends, selected me as Ambassador of the Year for our work saving turtles….they are the premiere turtle rescue hospital in America.  In 2012, I was also selected as Oceana’s International Ocean Hero.  Our town, Ft Pierce, won the Toyota/Wyland Mayor’s Challenge for Water Conservation in 2012.  Our waters here have cleaned up so well, that the County has reopened their once massive oyster industry and we are having our 2nd Annual Oyster fest in April.  I have spoken to over 11,000 children over the last three years and initiated the start-up of 7 other groups such as MCII around the state.  I state in my presentations that, “in 2001, I was viewed as a Carpetbagger from Ohio coming here to tell ya’ll how to deal with garbage.  Now I am more like a Chea pet and am growing on you.” We are not without our detractors, but we continue to remove huge amounts of debris with each event and are now well past the 350,000 pound mark. MCII has over 28 Proclamations and dozens of letters of support from POTUS, former Presidents, Governors, congress people, Mayors, Commissioners and civil leaders.  Our efforts are not only being felt, they are being seen.  Removal of debris reduces the back-log of silt and allows it to flow naturally.  When it becomes trapped in debris, it breaks free during storms or high winds and clouds the waters, falls upon sea grasses and chokes them out.  Our water is noticeably clear and testing far better than waters not addressing debris issues. We now are received as celebrities and school kids flock to see us and become Water Warriors.

Jeff:  What kind of people come on the Debris removal sessions? What age groups are they?

Don:  All people come to our events.  I have a blind diver, I have several disabled divers, I have kids from 16 to adults over 70.  Our events aren’t just for divers. We use captains, boats, deck hands, schleppers, shore “bubble watchers”, communications teams, kayakers, SUP’ers, jet skiers, we transport people to islands to walk and collect. We have sorters, weighers, party set-up help, people to give presentations, gather supplies, and send out press releases and dozens of other cool jobs.  We have every kind of person there is and we are always looking to engage more…mainly kids.  Kids will grab this concept and work hard to make it right.

Jeff:  What happens to all the waste?

Don:  This is the biggest part of what we do.  We separate the debris into groupings:  bottles and cans; plastics; fishing line and nets; fishing hardware; anchors, chain and rope; construction debris; tires and batteries; and misc.  We weigh it. We separate out organics and living critters… we release them. We remove the cool encrusted fishing poles and reels and set them aside along with some debris we use for displays and presentations. We then open our trash for the public to pick through.  Local fishing die-hards go for lead and lures, dive shops pick the lead out, others line up for anchors, chain and rope, lots of people grab bottles and cans and campers take the wood and burnables.  What we have left we dispose of properly.  We have great success reducing the debris down over 60%.  When local plastics recyclers are geared up, we do far better at reduction.

Jeff:  Are there any laws in place to stop future waste disposal? Are they enforced if there are?

Don: There are laws and they do not enforce them.  Cruise ships and cargo ships are the worst.  We need to catch them and then sue them to get any results.

There are many large businesses who could be Pro-active and support the litter removal caused by their products, but not so much. You would think environmental and other similar agencies would be falling over themselves heralding our efforts and results, but, not so much.  We have received some funding from SFWMD, but hardly any other support or recognition. However, local municipalities have become very strong supporters and advocates.  They have issued restrictions on plastic throw away service ware at outdoor events and put in-place biodegradable product usage to replace them.  We have pressed to have solid lids on all trash can to stop the darned birds from littering.  We have engaged the local marine patrols to “place a moratorium” of fines for littering on Spoil Islands and make announcements of same while we set-up our cleanup operations and engage the public out there.  As they weren’t fining them anyway, this is easy and the net gain should be we can slow down or stop some of this obvious littering. We are engaging law enforcement to enforce the laws that exist. We are hopeful.  Using the “baby steps” approach, and not finger-pointing at boaters, fisher people, campers and water enthusiasts, we have gained some gradual support.  Our divers, our logo flags and T-shirts have a trending value and Captain Don is always out there getting recognition and representing the efforts.  This has helped buoy the efforts.

Jeff:  Do you know if other groups have seen what you do and have taken up the initiative?

Don:  Yes, many groups have popped up as a result and we consult with coastal communities all the time.  Sea Angles, Ocean Hour, Loggerhead Blue Friends, Ocean Rehab, REEF, Masked Marlins, Surfriders, and numerous dive shops and local groups are much more active now they are supported and accepted.  Many volunteer groups have stepped up and conduct beach cleanups on a weekly or monthly basis. We have many groups we supply with mesh collection bags that are donated to us. We are thrilled at the movement and acceptance of what should be just plain commonsense. The message is clear, our photos and displays are harsh, bold, frightening and stark.  We are killing what was left to us to protect. Fish and birds eat debris and it kills them and eventually, it will poison us when we eat those critters.  Our motto:  “Out of site doesn’t make it right” says it all.

New report shows simple measures needed to cut beach plastic pollution

Published

beach

The Marine Conservation Society has launched its annual State of our Beaches 2023 report, highlighting the need for less single-use plastic items and more refillable options.

The charity’s beach cleaning programme, now in its 30th year, asks volunteers to record all litter that they find within a 100-metre stretch of beach. By gathering vital data from across the UK and Channel Islands, the charity creates change for cleaner seas and a healthier planet through policy and industry change. Last year, over 148 kilometres of beach were surveyed by volunteers, who removed 17,208kgs of litter from our coast.

Using data collected by over 14,000 volunteers, the State of our Beaches 2023 report shows that half of all litter collected came from public sources – either dumped, blown or washed onto our beaches.

Drinks-related litter, such as plastic bottles, caps and cans were one of the most found items, with an average of 16 found per 100 metres of beach surveyed. This figure is up 14% compared to the charity’s 2022 report.

Plastics caps and lids were recorded on 89% of surveys, with over 30,000 found in total. Plastic bottles were also commonly collected, with 73% of surveys finding this single-use item – a 4% increase compared to 2022. The charity’s inland litter pick survey, Source to Sea, also reported finding plastic bottles on 92% of cleans.

However, the charity’s State of Our Beaches 2023 report also indicates that some types of litter are on a downward trend. Although still in the top 10 litter items, disposable plastic cutlery, trays and straws were found on 5% fewer beaches across the UK, showing that bans on these plastic items between 2022 – 2023 could be working. The presence of plastic cotton bud sticks also dropped by 14%.

Lizzie Price, Beachwatch Manager at the Marine Conservation Society, said, “Half of the litter found on our beaches originates from public sources, underscoring the pressing issue of single-use plastic. Evidence shows that refillable alternatives and litter return schemes effectively reduce rubbish, as demonstrated by the decline our data has shown in items like plastic bags and disposable cutlery.

“Urgent and decisive action from UK governments is needed to accelerate our shift towards a circular economy, where we reuse, repair and recycle. The public needs greater access to refillable products and systems need to be implemented in which manufacturers are responsible for their waste.”

Governments across the UK have committed to delivering deposit return schemes from October 2025. However, the proposed scheme in England does not include glass items, despite glass being found on 52% of beaches in 2023. The charity is calling for governments across the UK to introduce compatible all inclusive deposit return schemes as soon as possible. This would see aluminium cans, and plastic and glass bottles have a 20p deposit which would be returned when recycled which would reduce drinks-related pollution.

Businesses are, however, starting to take refillable and reusable options into their own hands. Supermarket chain, Aldi, the largest corporate funder of the charity’s 2024 Beachwatch programme, is already leading the charge in refillable items by trialling refillable options for cereals and porridge oats in their stores over the past 5 months.

Plastics and Packaging Director, Luke Emery, from Aldi, who are running 4 beach cleans for staff and volunteers in 2024, said, We are continually working to reduce single-use plastics and packaging, and making unpackaged product options more commonplace for our customers is a key part of this. We are really pleased with the uptake of our refillable range so far by customers. Not only are we making sustainable shopping more accessible, but we also offer refill products for a better price than the packaged alternative, helping our customers save money.”

Marine litter is one of the biggest threats to our seas, with plastic breaking down over time into microplastics and threatening marine life which can ingest or become entangled in them. The Marine Conservation Society is urging the UK Government to move faster on its policies to cut down plastic waste and prevent items from reaching our seas.

Guarding Against Coral Invaders

Protecting (Dutch) Caribbean Reefs from Unomia stolonifera

Recent reports highlight the concerning spread of the invasive soft coral, Unomia stolonifera, currently devastating Venezuela’s marine ecosystems and detected in Cuba. With the potential threat of its expansion to the (Dutch) Caribbean islands, urgent action and awareness are essential to safeguard marine biodiversity and local economies from possible catastrophic consequences.

Invasive species are animals or plants from another region of the world that don’t belong in their new environment. These species can have major ecological effects by decimating native flora or fauna. They can also cause large economic losses and impact human health. Invasive species also pose a significant threat to marine ecosystems worldwide, including the Dutch Caribbean. Among these invaders is the octocoral species Unomia stolonifera or “Pulsing Xenia”, originally from the Indo-Pacific. With its rapid growth and lack of natural predators, this species can outcompete native species and disrupt fragile marine habitats such as seagrass beds and coral reefs.

Background

The invasive soft coral U. stolonifera was first identified in 2014, off the coast of Venezuela. It is believed to have been introduced via the illegal aquarium trade.  Since this species can reproduce sexually and asexually (or fragment), even small pieces can regenerate to spread.  Once introduced it quickly took over shallow reefs and hard substrate at depths of 0-50 meters, outcompeting local corals and seagrass for space.  Follow on surveys found that this coral species exhibited average percentage cover as high as 80%, vastly outcompeting native corals. In highly colonized areas, fish are disappearing due to loss of habitats.

In 2022, during a survey conducted in Cuba by the University of Havana, an unknown octocoral was discovered which was later identified as the invasive Unomia stolonifera. It is suspected that the coral larvae arrived in ballast water from fossil fuel ships originating from Venezuela, as nearby sites adjacent to Venezuelan ports have been heavily affected by the invasion.

How to help

Prevention through continuous monitoring, particularly in high-risk areas such as marine harbors and oil facilities, is paramount. Early detection plays a pivotal role in mitigating the threat posed by Unomia stolonifera.

The public’s involvement and awareness are also vital. Local communities, recreational divers, tourists, and all stakeholders are urged to participate in early detection efforts by reporting sightings (photo, location and date) of this invasive coral to their respective Protected Area Management Organization (PMO’s)- the Fundacion Parke Nacional Aruba (FPNA)STINAPA BonaireCARMABI Curaçao Saba Conservation Foundation (SCF)Nature Foundation St. Maarten (NFSXM) and St. Eustatius National Parks (STENAPA). If an invaded area is confirmed, follow the recommendations by the local PMO’s.

Keys to Success

Despite the challenges, early detection is key to mitigating the threat posed by Unomia stolonifera. With continued vigilance, research, and community engagement, there is hope for containing this potential issue before it becomes a major threat.
