“Be the change that you wish to see in the world.”― Mahatma Gandhi
Almost two years after the announcement of the Mission 2020 Pledge, nearly 200 dive industry organizations and businesses have pledged to do their part to reduce their company’s impact on aquatic environments.
For those of you who haven’t heard of it, Mission 2020 is a collection of pledges from organizations in the diving industry to change their business practices in order to help protect and preserve our oceans for the future. The primary focus of the pledge is to reduce or eliminate single-use plastic before World Oceans Day in 2020. Plastic is an issue that is at the forefront of a lot of consumers minds. Scientists from the nonprofit advocacy group “5 Gyres” found there are 5.25 trillion pieces of plastic debris in the ocean. Of that, 269,000 tons float on the surface, while almost four billion plastic microfibers per square kilometer litter the deep sea.
Mission 2020 was founded by UK-based dive garment company, Fourth Element in hopes of combating their contribution to the growing plastic problem. We caught up with 4E co-founder Paul Strike who is in charge of product development to see what the state of Mission 2020 is now.
How did Mission 2020 come about?
Jim [Standing] and I had a number of conversations at the 2017 DEMA tradeshow about doing something for the environment. A couple of months later we were discussing it [Mission 2020] again and came up with an idea: Wouldn’t it be amazing if we could actually encourage other people, other companies, to join us and do something that would make a difference? That’s how Mission 2020, as the industry knows it, was born. It’s not about Fourth Element, but about developing an industry initiative that will allow all of us to speak with one voice.
So it would have more power than just a single company behind it?
Yes, that kind of combined effect of having a number of companies: actually, in fact, a whole range of people and businesses and brands, dive centers, and organizations involved in the scuba diving industry, all coming together with one common cause– to do something positive for the ocean. There are nearly 200 entities that have made a pledge to effect change under that Mission 2020 heading. We are an industry that enjoys the ocean and makes a living off of it, so it’s in our best interest not to screw up our playground.
A strong and powerful message is being presented by the diving industry through Mission 2020. It could be the only and is certainly the first industry in the world to take some kind of combined, unified stance on this, one that is sending a strong message to consumers and other businesses.
Why did Fourth Element choose to focus on single-use plastics?
Well, think about how much plastic is involved in packaging a pair of scuba fins. And that’s a big, relatively heavy-duty plastic bag with a plastic carry handle that sometimes clips together. And I suppose it would be interesting to find out how many pairs of fins are sold in scuba diving. You know, that’s probably hundreds of thousands, isn’t it? And that’s just one product! It’s scary. That is just a huge amount of plastic. The magnitude of these plastic stats and of what’s going on globally is just… It’s mind-boggling. It’s so huge, the impact, it’s almost a bit like when people are talking about distant planets; it’s very difficult to get your head around it because it’s too big.
Thankfully, it’s something that so many people are talking about and obviously not just in the dive industry. You can’t seem to turn on the TV without there being something about plastic. Thankfully, there are lots and lots of companies changing things. But equally scarily, there are lots of companies that don’t seem to be making any changes.
What are you changing in order to reach your Mission 2020 goals?
Jim and I are both equally committed to trying to achieve these goals. The whole company is behind this mission. From the people designing and creating the clothing to those packing and dispatching it everyone in the company is behind this.
With hand on heart, we couldn’t promote an environmentally positive product, something that’s been made from recycled nylon, and then put it in a plastic bag. Obviously, on one hand, we were doing something that was in some way beneficial, while on the other hand, completely eradicating it. So that made us look more carefully at the packaging. And we have found various, or we have tried various means to package our Ocean Positive swimwear, ways that would be without the use of plastic right down to the Kimball tags and everything.
That’s your swimwear line made from recycled ghost finishing net right?
[Note: In 2009 the United Nations Food and Agriculture Organization (FAO) and the U.N. Environment Programme (UNEP) estimated that there were approximately 640,000 tons of abandoned fishing nets in the oceans, accounting for one-tenth of all marine litter.]
What is your timeframe?
Our deadline, our self-imposed deadline, is the World Oceans Day in 2020, by which time our ambition is to be single-use plastic-free from all of our packaging. And it will have taken us the better part of two years to get there. It’s not just a linear progression. We’ve made some leaps ahead, and we’ve changed quite a lot of things already. By the end of this year, we should be almost there, if not all the way there [single-use plastic free]. But I suspect we may have one or two little nuggety ones to solve in the early part of 2020.
And I think again, that’s the sort of message I’d like to put out there to everyone: as much as we all need to change our behavior to reduce the waste of single-use plastic, I think it’s unrealistic to expect individuals and/or companies to change everything overnight and some immediate changes may not be the perfect solution, but steps along the way to achieving a perfect solution and a necessary part of the process.
What are some of the difficulties 4E faced in achieving their plastic-free goals?
I mean there are so many variations, there are so many things to consider in this process. Everybody will have their own challenges, ones that are specific to their company structure and their supply chain. So it’s a multilayered, multi-complex challenge and a huge problem to resolve.
For us, it’s time-consuming, it’s expensive, it’s challenging. Unfortunately, the plastic bag is so good at what it does in terms of protecting a product. It’s clear; you can see the product through the bag. It’s cheap. It’s waterproof, just to name some of the beneficial characteristics of a plastic bag. And it’s incredibly good at doing what you actually want it to do.
The major downfall is that it stays around for hundreds and hundreds of years afterwards. And of course, we’ve seen the result of that in waterways around the world and horrible wildlife footage where you see whales that have been cut open with thousands of these bags inside of them. So trying to find a product, or safe products, that actually replicate the plastic bag is challenging.
What kind of replacements have you found so far?
We have investigated and used bags that are made from vegetable-based or plant-based material. And that works pretty well for a lot of products, for a lot of situations. But it has some limitations. And unfortunately, it’s not a kind of one-stop-shop of going, “oh great, we’ve got a replacement for the plastic bag! However, we do have a plastic bag type thing made from plant material which biodegrades, and it actually will break down in the water, and it can be eaten by a turtle and it doesn’t kill them. It can be digested by sea life. But unfortunately, it has its challenges with temperature, and it can get brittle, and sometimes it can crack. So it doesn’t achieve all of what we need it to achieve.
We’ve used paper bags, we are increasingly using paper bags for our T-shirts, which we then need to label very clearly. And so then, of course, we need to look at a paper-based sticker that is using a glue that is non-toxic. And that’s another little problem to solve.
Every step of the way there seems to be another step or two related to it which is something that needs to be resolved or something that needs to be overcome; whereas your plastic bag is so damn simple. And that is the fundamental problem.
So are there companies working on these problems?
There are companies that are taking the technology a bit further, there are better solutions every day. We are constantly looking at these because we haven’t found the ultimate solution, and they work for some products and not others. Sometimes there are size limitations to what’s possible and sometimes there are cost limitations to what is possible as well. So there are magnitudes of scale and economy like that, which can get quite scary from a cost point of view.
The other challenge is sifting through the actual science, the real science, behind the bags. Because a lot of the bags that are coming out, or at least some, will biodegrade. But they don’t necessarily biodegrade into biomaterial. They biodegrade into small particles of plastic, which is not what we want. The bag ceases to become a bag and it breaks down into little bits of plastic, but that really doesn’t solve the problem at all.
So, not every solution you’ve found solves the problem?
That one solves some element of the problem, that it’s less of a hazard to marine life. But the little bits of plastic will end up getting into the water table and will get into rivers and then end up being flushed out to the ocean. It’s the same way that the microfilaments that washed out of your fabric or your garments when you put them through a domestic washing machine, you’ve got the same fundamental problem there. These little microfilaments of plastic. So it’s pointless replacing a plastic bag with a bag that just breaks down into tiny bits of plastic. So you have got to be careful with regard to what types of solutions you find.
There are some real challenges, and they all take time. But we are getting there. And I think what is really encouraging, and we’re not saying that we’ve solved this problem, but the more little steps that we all take toward achieving the sort of endgame of eliminating single-use plastic, the more solutions that become apparent in the process.
Nice! How do you feel about industry participation in Mission 2020? Has it been well received by the dive industry?
I looked through the list again today to see who has signed up. And I feel really heartened by the fact that a significant number of brands and companies have jumped on board with it and made their commitment to do something different in order to benefit the ocean environment. Obviously, we make quite a few competitive products to some of the brands but it’s really been encouraging to see who has come on board. It’s fantastic that they are seeing the bigger picture.
We’ve got PADI. It was fantastic to get PADI on board. They exert so much influence in the world of diving generally, and they’ve encouraged a lot of their dive centers throughout the world to consider getting involved. GUE has already signed up and is doing the same. It’s fantastic to get major training agencies on board. That creates a great deal of influence amongst the diving industry, the diving market, and people who are involved in diving.
A lot of dive centers have also become involved. We’ve got dive centers that have signed up from Bali to the USA to the UK, virtually globally, and have made a commitment to doing things differently. I’m not exactly sure of the density in the areas that are the most significantly represented, but I was really quite encouraged by how widespread this has actually become.
What challenges do you face with improving the sustainability of your products?
The neoprene that we use in our wetsuits contains between 15 to 20% recycled material from car tires. So it’s an effective recycling process of car tires where 85 % of the car tire is recycled, and the black rubber material is integrated, or is used in the production of the neoprene and accounts for between 15 and 20% of the neoprene that is used in our suits. So again, it’s not the end game, but it’s a step in the right direction.
There is a huge amount of investment going into the reuse and recycle-ability of neoprene. And it may be that the endgame or the ambition of recycling neoprene wetsuits to make more neoprene wetsuits is probably a long, long way off because of the nature of the neoprene once it’s been laminated with the linings inside and out and stitched together etc. And then in order to recycle that material, that suit, there are many processes involved.
And that is one of the biggest impediments and a huge challenge to any recycling process, for when you have mixed materials and mixed construction, it becomes much more challenging to recycle that product. It’s almost impossible to separate different forms of plastic because they have different properties. So that is something, again, in this whole manufacturing process that we’re thinking more about. Like, what we can do to make the product easier to recycle at the end of its life? That’s another thing, going back to wetsuits, I think it’s much more realistic to think of neoprene wetsuits getting recycled for repurposing not as neoprene wetsuits anymore but something else that perhaps requires material similar to neoprene.
How about with your clothing?
Well, basically certain garments shed little microfibers more than others. And it often depends upon how tight-knit that fabric is. And you have a traditional fleece, and the fluffy surface is created by brushing loops, knotted loops of polyester, usually, and breaking them and splitting them and fluffing them up, shall we say. Now that obviously damages these loops and it breaks them and consequently, that is then more susceptible to little fragments breaking off in the washing process. So if you had a garment with the same composition but it’s tightly knitted and hasn’t been brushed, then it sheds fewer filaments.
So a rash guard and swimwear, by the nature of their construction, will shed many, many fewer filaments than a fleece that has been brushed significantly to create a fluffy, soft-feeling texture. Also, there is some evidence that at least suggests that the better the quality of the knit or the better the quality of the fabric, by and large, there is a reduction in the number of filaments that are lost because the knitting process is higher-quality, is a more secure knitting and in effect the garment doesn’t shed its yarn quite as easily. I’m afraid I’ve become a self-confessed fabric geek. I know more about fabric and knitting than I ever wished to know really.
What are the future plans after Mission 2020 has “ended”?
Obviously continued commitment to do what we can do, and hopefully, we will have eliminated single-use plastic from our packaging. I’m pretty confident that we will have achieved that. And part of the Mission 2020 statement is also about our continued quest for using recycled materials in our product range and looking for alternatives to harmful plastics. Some of our products use waterproofing technology which is less chemically toxic. The water runoff is cleaner.
We are actively working with fabric producing fabric knitters that are investing in more sustainable processes in their business. So, basically we will continue to choose a supply chain that minimizes environmental impact over ones that are carrying on as normal, shall we say. It’s about the plastic, in effect, but it’s also about the bigger picture. Therefore, we will continue to invest in and develop less impactful processes in the supply chain and production of our products.
Do you have hope for the future?
Obviously as we are all very aware, elimination of the single-use plastic is a global issue and I’m excited by going online and finding that there’s been a new breakthrough with this or somebody’s investigating this or come up with a technology that may not be the end game, but it’s improving and it’s making progress. We shouldn’t feel like we’ve failed because we haven’t gotten to the end game straightaway.
And what the great thing about all these things is that the more that companies actually look for these products, the more there are manufacturers and companies starting up, creating and selling products to replace plastics. When we started, there seemed to be only one viable option available. I’m sure it wasn’t one, but we found there were very few options in terms of getting something that was like a plastic bag, but not plastic. And now there seem to be more and more alternatives springing up every month.
What about consumers? There are an estimated 500 billion single-use plastic bags used each year by shoppers.
Ultimately, it comes down to consumers because they are one of the most powerful drivers, from a company’s perspective, as we all know. The movement depends on them. Once consumers become aware, take a stand, and actually change their behavior, companies will have to come around. If a company experiences a decline in the sale of a product because aware consumers see little to no effort toward reducing or ending single-use plastic, the company will have to make changes.
And I suppose this is almost a kind of plea or mandate to consumers to think about your choices. Of course, if it costs more to buy the environmental product. And some people may be lucky enough to be able to do that, but many people aren’t. However, we are finding that the price difference between an environmentally friendlier product, whether it’s the way it’s packaged or the way the materials are used, is getting narrower.
As for Mission 2020, it would be great to see the dive industry as a whole adopt this challenge.
Global Underwater Explorers has made a Mission 2020 pledge. At GUE, we pledge to launch an annual GUE Cleanup Event. We feel we can have the greatest impact by utilizing our network of divers in a worldwide cleanup of our waters. We hope to power our office with solar in the near future, will continue to recycle, and eliminate any single-use plastic from our products.

Deep Drift Diving in Cozumel
With its spectacular reef encrusted walls and irresistible current Cozumel has been a ‘Mecca’ of recreational diving for nearly thirty years; mind that 130-ft/40m depth limit! Now explorer and tech instructor Alberto Nava takes us on a journey to rediscover the parts of underwater Cozumel that single-tank tourist divers will never see. Are you ready to mix it up and conduct some unapologetically DEEP Cozumel drift diving?

After doing all my closed circuit rebreather (CCR) critical control checks, i.e., “CHAOS,” I jumped into the water to find myself in warm, cobalt blue water. We descended to 6 m/20 ft, did a quick bubble check, and started our descent. My automatic diluent valve (ADV) delivered a wonderful trimix 15/60 (15% O2, 60% helium) mix as I dropped down the wall and leveled off at about 60 m/197 ft. A large black grouper came to greet us, and we quickly reached the 65 m/213 ft overhang on the wall—the old coastline from the previous ice age. We followed the grouper inside the overhang and reached 80 m/263 ft. We found two large lionfish resting on a sizeable white sponge, and large strands of black corals and colorful gorgonian were all around. We turned our bodies into the current and began our 180-minute drift dive along the incredible walls of Cozumel. We were in heaven!
As we drifted along enjoying this incredible dive, my mind drifted back 20 years ago,
when I used to dive the Caribbean Sea in my home country of Venezuela. At that time, I had just become a PADI divemaster and used to take people on warm-water adventures in Venezuela’s national marine park, Los Roques Archipelago, near the island of Bonaire. As a divemaster, we limited our dives to 30 m/100 ft and closely followed the no-decompression limits. The tools of those times were single aluminum 80 (AL80) tanks, a warm-water wetsuit or no wetsuit at all on some dives, and the famous multi-level diving PADI wheeI.
In my 20-year evolution as a diver, I’m so thankful to have found the Global Underwater Explorers (GUE) organization and its amazing mentors, which made my 180-minute dive to 70 m/230 ft seem as simple as the old single tank diving of my past. Is this for real? Can Caribbean diving be even more incredible with GUE tools? Please allow me to take you on my rediscovery of the Caribbean during the last three years, with the hope that you will also enjoy the incredible natural resource we have at our disposal.
In 1998, as technical diving was just getting started, I moved to California after spending a few years attending school in Sydney, Australia. My time in Oz had left me a bit frustrated, having experienced what I now perceive as dangerous deep air dives in the Sydney Harbor as well as in the caves of Mount Gambier, near Melbourne. I arrived in California wanting to learn to use alternative breathing gases for going deeper.
I experienced improvements on the diving procedures and gases while training with West Coast technical diving pioneer Wings Stock from Santa Cruz, where we used to breathe trimix 20/20 (20% O2, 20% helium) at 67 m/220 ft. But, it was really not until I took my GUE Tech 1 class in 2001 that deep diving came to a new light. Helium was such a wonderful gas to put in our tanks, and the more the better. For me, doing a 46 m/150 ft dive with 35% helium removed most of the ambiguities of deep diving, reduced the risk, and made deep diving a much more enjoyable experience.
Living in Monterey, I was able to explore and document many of our deep water pinnacles, including those at Point Lobos Marine Reserve, Big Sur Banks, and others.
Unfortunately, I quickly forgot all about the Caribbean and settled in as a cold-water California diver. During that time I also started going to Mexico to dive the amazing caves of the Yucatan Peninsula.
Fortunately, I got better at cave diving, got into exploration, and was lucky to discover the Hoyo Negro Pit and an amazing assembly of animal and human remains from the Late Pleistocene. From 2007 to 2014, Hoyo Negro, underwater archaeology, and scientific diving were at the center of my diving world. As time went by, my distant past as a Caribbean diver faded more and more from my diving horizons.
The Return to the Caribbean
In 2014, I reluctantly agreed to a warm-water diving vacation with my girlfriend. Cozumel was close to the caves, so I figured I could do my cave diving project, then spend a few days of diving Cozumel in order to make everybody happy. However, as soon as I jumped into the water, I recognized the warm, blue water surrounding my body and realized I had been there before; in fact, it was imprinted in my mind.
I was quickly able to find all the little creatures inhabiting the reef, including seahorses, green moray eels, and arrow crabs, and the larger creatures as well: barracudas, eagle rays, and nurse sharks. I felt about 20 years younger, having returned to my natural environment. On the second day of diving, after the divemaster gave us a check out, we ventured to the Cozumel wall. We quickly dropped to 30 m/100 ft, and I could see the wall going down, probably to 60 m/197 ft. I immediately wanted to go deeper on the wall and explore! However, considering my minimum gas reserves, equivalent narcotic depth (END), and maximum operating depth (I was diving nitrox 32), I realized that I needed the right tools.
By the end of the trip I was convinced I needed to come back to Cozumel with GUE tools. At a minimum, we needed to ditch the single tanks for doubles, or better yet a rebreather, and find a way to get helium, Softnolime, and a reliable boat operator willing to conduct some fun tech dives.
I got back home and started talking to Cozumel veterans about how to get the equipment and support I would need for deeper diving. The most common answer I got was, “People in Cozumel don’t like deep diving.” There had been too many accidents, so they didn’t want to take people deep on the reef. Furthermore, my inquiries with dive operators were not successful; the best answer I got was that some shops had larger steel tanks.
I eventually found a dive operator who was willing to conduct deep diving and had a great boat and crew. Unfortunately, the owner of the shop had had problems with GUE divers from the early “Doing It Right” era of the ‘90s, and thus was not very welcoming to me as a GUE diver or instructor. It took a lot of energy to convince him that I was a nice person, and that I was not going to call him a “stroke” or require him to wear all Halcyon dive gear. After numerous meetings, dinners, and some mescal, I finally had access to a good boat, an experienced crew, and the all-important helium.
Fun Diving GUE Style
Over the last three years, my friends and I have conducted numerous fun dives in Cozumel and held some simple classes. Here is a description of what’s possible starting with the simplest diving and going to the more complex.
- Recreational diving with doubles: For me, this is entry-level Caribbean diving. You get two sets of doubles filled with 32% and conduct two dives in a day. Each dive is a multiple-level “no-stop” dive on the reef with a max operating depth (MOD) of 30 m/100 ft. Total run times are around 75 min, and typical dives have three levels with 20 min at 30 m/100 ft, followed by 20 min at 18 m/60 ft, and another 20 min at 10 m/30 ft. Divers then use their remaining gas until their runtime is in the 75 min range. Our boat operator allows for two 75 min dives when doing recreational dives. This allows for good time at depth followed by fun diving along the wall. All that’s needed to participate in this type of diving is GUE fundamentals and a doubles primer.
- Tech 1 dives: For GUE Tech 1 divers, the equipment of choice is a set of AL80s typically filled with trimix 18/45, and a nitrox 50 (50% O2) AL80 stage for decompression. This is the perfect combination of gear to venture on the wall with a max operating depth of 52 m/170 ft (Note that GUE standards set a maximum pO2 of 1.2 atm during the working phase of the dive, and 1.6 atm during decompression), and again a run time of 75 to 85 min. Divers can multi-level their dives into two segments with 15 min spent at 52 m/170 ft and another 15 minutes at 40 m/130 ft, followed by a nice relaxing deco drifting along the shallow reef. In order to increase the fun during deco—we call it “Fun Deco”— we make the stops longer and spend more time on the reef. A typical decompression profile might be five minutes starting at 21 m/70 feet on nitrox 50, five at 18 m/60 ft, five at 15 m /50 ft, five at 12 m/40 ft, five at 9 m/30 ft, and 10 min at 26 m/20 ft. It’s easy and FUN! AL80s and wetsuits are also an ideal combination; no need for a drysuit there. During the summer months the air temperature is around 90 degrees Fahrenheit, and the water might be as warm as 87 degrees Fahrenheit.
- Tech 2 dives: As people want to dive deeper on the walls, GUE Tech 2 divers get either a bottom stage to increase their time at depth, or we also have low pressure LP85 tanks available for them. They typically use both nitrox 50 and O2 for decompression. The best part of the reef is the old coastline in the 60-80 m/197-262 ft range. In order to make their gas last longer, T2 divers can also multiple-level their dive, dividing their bottom time between maximum depth and time at 45 m/148 ft. In Cozumel, there is plenty to see at maximum depth. Similar to T1 divers, decompression is done on the reef and plenty of time is spent in the 12-9 m/40-30 ft range while still on the reef, until heading out to 6 m/20 ft for a bit of O2 deco. While at 6 m/20 ft, you can still enjoy diving as you look at a school of barracudas, trevally jacks, and the occasional shark. Watching turtles is one of the treats during decompression.
- CCR dives: The ultimate Cozumel tech dives are conducted by rebreather divers. The operator allows us to drift for up to 180 minutes, but in exchange for the long bottom time, we only conduct one dive. It’s not uncommon to have bottom times in the range of 60 minutes in the 70-80 m/230-262 ft range. These profiles require longer deco but one does so drifting along the Cozumel reefs.
The CCR allows for more flexible decompression and increases the enjoyable part of the dives. It’s not uncommon to extend the stops in the 37-21 m/120-70 ft range diving inside a coral head. We often make our stops for 20 minutes every 3 m/10 ft on our way to the surface, which allows us to stay on the reef for most of the dive. Our 6 m/20 ft stop is not much longer than the previous stop, which is a big change for people accustomed to long 6 m/20 ft stop hangs.
All in all, diving Cozumel with the appropriate tools provides for an incredible experience and allows you to practice your skills in a wonderful and warm environment. I plan to organize several trips to Cozumel in 2020. I hope you’ll be able to make it.
Beto will be running a number of ‘tech” trips to Cozumel in 2020. If you are interested please contact him at: firstname.lastname@example.org
Alberto “Beto” Nava is a Venezuelan-American engineer, diver, dive instructor, and explorer based in California. He has over 18 years of diving experience and has completed over 500 cave dives. His longest cave exploration penetration dive has been 4.7 km/15,500 ft. He and his group of fellow divers particularly enjoy exploring the cenotes in the Yucatan region of Mexico.
It was on one of these excursions that he and his colleagues discovered Hoyo Negro, or “Black Hole.” The bottom of Hoyo Negro contains bones of several Ice-Age megafauna and bones of a young girl who lived 13,000 years ago. They named her Naia. This discovery started one of the most important studies of the first Americans in recent history. From 2011 to 2015, Nava was a National Geographic Explorers Grant recipient. He used the grant to continue diving and photographing Hoyo Negro. His photography is now being used in the innovative labs of the Cultural Heritage Engineering Initiative at the Qualcomm Institute at the University of California, San Diego, to create a unique 3-D experience of Hoyo Negro for those who cannot do the difficult dive and would like to experience and study the space.
Nava has also published several papers on diving, underwater mapping, and the discovery of Hoyo Negro. He holds bachelor’s and master’s degrees in computer science from the Simon Bolivar National University in Venezuela and has worked as an engineer for over twenty years.
