Students were inspired to appreciate the difference that they could make individually to help protect the environment. This event was organised by the Bermuda Zoological Society (BZS) and sponsored by the Ernest E. Stempel Foundation; the venue was the Bermuda Aquarium, Museum & Zoo and it was supported by the Department of Conservation Services and the Bermuda National Trust. This was the fifth biennial event held in Bermuda and students aged ten and up had the opportunity to meet many of Bermuda’s local scientists and eco-heroes. They also took part in workshops designed to give them hands-on experience in conservation projects. For many of the delegates this was the first time that they had really explored Bermuda and they were given only one responsibility; to learn as much as they could about the environment and to consider ways in which they could protect it. This conference also provided a chance to showcase some of the more secluded natural areas in Bermuda including the Alfred Blackburn Smith Reserve and the exploration of Harrington Sound by boat. continued next page “To inspire appreciation and care of island environments” 1 The keynote speaker for this year’s conference was research development Manager Sophie Benbow, of the award-winning marine research group Blue Ventures in Madagascar. Ms. Benbow had recently returned from Madagascar and was eager to inspire our local delegates with stories of what others are doing around the world to protect the environment. The Blue Ventures organization is a great example of “The Power of One” because it is the result of two college students who dared to dream Visiting the new about how they could protect Recycling Plant the marine environment in that part of the world. Bermuda Zoological Society and the Bermuda Aquarium, Museum & Zoo look forward to working with Blue Ventures in the future. The Environment Minister, the Hon. Elvin James JP, MP, was on hand to give an official welcome at the beginning of the conference and also presented certificates to each student at the event’s closing ceremonies at the Bermuda Underwater Exploration Institute on Friday, April 18. “One thing that was evident across Trash cleanup on the board was the railway trail high level of environmental awareness amongst the delegates. They were very eager to learn ways in which they could actively get involved and make a difference. So, although there is much more environmental education that needs to take place, it is encouraging to take note that the eco-heroes of tomorrow are listening and learning. I believe that with our continued encouragement and support, the youth today will be well-equipped to face the environmental challenges of tomorrow.” Joseph Furbert Education Officer 2 Square foot gardening GPS (global positioning system ) & GIS (geographic information system) workshop Fish conservation in Bermuda Making new friends “To inspire appreciation and care of island environments” Photos: Lynn Thorne membership & development Thank you, Ross “Blackie” Talbot Charity Classic!

In a world where it’s eat or be eaten, only those with the greatest assets (and the skills to use them) can survive and it’s not always the biggest and the strongest. A particularly potent weapon utilised by sea creatures is toxin. We know how effective toxin can be when used offensively as demonstrated by snakes and spiders but it is equally as effective when used as a deterrent as demonstrated by toadstools and poison dart frogs. To clarify the biological usage of toxin; something is said to be poisonous if it is consumed or absorbed and venomous if it is injected (e.g. by a bite or sting). Spotted scorpionfish (Scorpaena plumierl) The use of toxin is advantageous in a number of ways. It enables weaker less agile predators to immobilise larger or more agile prey; it can be used in defence when threatened or attacked and it can be used as a deterrent to predators who learn that consuming that toxic creature can have disastrous effects. The two most common biological toxins are neurotoxins which disrupt nerve functions and haematoxins which destroy red blood cells. 4 The ocean is also home to some of the world’s most powerful toxins. It can be found in some of the smallest organisms like algae up to larger creatures like stingrays. Luckily, Bermuda is considered to be extremely safe when it comes to the exposure of humans to marine toxins. Sea snakes, stonefish, blue ringed octopus and box jellyfish are just some of the potential dangers found abundantly in other parts of the world that can be deadly to bathers. Local toxic reactions range from mostly mild to occasionally severe with the cnidarians (corals, anemones and jellyfish) making up the bulk of the offending culprits. Fire coral, a hydroid, is a local resident that has spoiled an unsuspecting bather’s swim from time to time but the perennial ‘watch out’ for nasty is the Portuguese mano-war. This jellyfish floats around the world in tropical seas, a slave to the wind. Their toxin is quite painful “To inspire appreciation and care of island environments” aquarium news as many a Bermudian can attest to. Their tentacles can potentially reach 120ft in length and keep on stinging even after the animal has been stranded upon a beach. Of particular concern recently are the venomous lionfish which have somehow made it to our shores from the Pacific. A member of the scorpionfish family (with stonefish and scorpionfish), this invasive can inflict a painful, nasty wound from venom delivered through long dorsal and pectoral spines. Interestingly, its relative the spotted scorpionfish, is native to Bermuda and is also capable of producing the same wounds; but, there has been little record of people getting stung by them here. Many marine toxins are neurotoxic in their effect. They are mostly made up of complex molecules, peptides and/or enzymes and can be denatured or made less effective when exposed to excessive heat. One of the best remedies for a sting is to immerse the affected area in the hottest water tolerable for as long as possible as opposed to the emptying of one’s bladder. Various marine algae produce toxins. When some algae bloom in large numbers they can produce what is known as a red tide due to their making the water red in colour although other colours are also possible. Toxins are released by the algae during a red tide causing massive fish and other organism die-offs. Some dinoflagellate algae produce ciguatoxin which, in very small amounts, is harmless to humans; however, ciguatoxin can bio-accumulate in fish flesh through grazing of the algae by herbivores which are in turn eaten by carnivores. The fish at the top of the food chain will have higher levels of the toxin in their bodies than organisms lower in the chain making them unfit for human consumption. Humans eating fish with high levels of this toxin, like barracuda, can suffer from ciguatera poisoning. secretes thick mucus when it feels threatened which can froth up the water like soap. This mucus contains the toxin grammistin which is toxic to other fish. Another fish found in Bermuda with a similar defense mechanism is the smooth trunkfish whose mucus contains the toxin ostracitoxin. Taking the dose to ‘lethal to human’ level are Tetraodontidae fish (puffers). The bodies of these fish contain tetrodotoxin, a powerful neurotoxin also found in blue ringed octopus making them active ingredients in a last meal. Consumption of these fish is strongly discouraged although some areas of the world prepare pufferfish as a delicacy called fugu. The chefs that do this must go through years of special training to learn how to prepare the fish properly yet, in Japan alone, several people die every year just from eating ill-prepared fugu. The most lethal toxins are produced by Fire coral (Millepora alcicornis) the box jellyfish, which is common off north Cone snails are slow moving marine eastern Australia. Many people die snails which are highly efficient every year from their stings as they predators capable even of hunting are difficult to see and the most lethal ones have no antivenin. fish.

Which plants are these, you might ask? In a word, invasives! Invasive plants are plants that were introduced to the island. They self-seed and spread aggressively and “ultimately out-compete or over-shade virtually everything else and become monopolistic; and monopolies mean loss of biodiversity.” 1 Asparagus fern is a very visible example of a monopolistic plant. It forms a virtual curtain of foliage on the rock walls of most of our public roads. In nature reserves it often forms a ‘carpet’ of vegetation, covering and smothering other plants such as grasses that would otherwise provide food, in the form of seeds, for a number of our native and migratory bird species. Several government departments are actively working to reduce the negative impact of invasive plants on the island’s biodiversity but they can’t do it alone. It is becoming increasingly important that members of the public learn to recognize invasive plants and get involved in removing them from the landscape — starting with the property on which they live. I encourage people to: 1) commit to making their properties more biodiversity friendly, and 2) embark on a plan to remove, over time, any invasives, replacing them with more suitable plants that will support our native and migratory fauna (birds, bats, dragonflies and butterflies). Some other plants invasive in Bermuda include: Brazil/Mexican pepper .................... Schinus terebinthifolius Asparagus fern ..........................

In most cases, you will get a lot of photographs of the plant. 6 “To inspire appreciation and care of island environments” museum news As the song goes……Getting to know you…… Known to many people in Bermuda as schefflera (Brassaia actinophylla), this popular ornamental is also known as the umbrella tree, the Australian or Queensland umbrella tree, the octopus tree and starleaf. Native to Queensland, Australia, it was introduced to Bermuda as an ornamental. It now spreads naturally and is considered naturalized, verging on invasive. It is becoming common to see seedlings of schefflera growing out of walls and in crevices in trees. An umbrella tree can grow up to forty feet high and has a single, upright trunk with upright branches. Its large leaves are made up of seven to sixteen shiny oblong leathery leaflets, all attached to a central point at branch ends. Each leaflet is four to twelve inches long. A kiskadee delights in picking and eating an umbrella tree’s fruit The umbrella tree The umbrella tree bears its flowers on stiff branches which radiate out and up from the top of the trunk. These floral branches are two feet long and bear round heads of small red flowers and look like an octopus’s suckers. The fruit, which follow the flower, contain ten to twelve one-seeded dark purple nuts and are very popular with pest birds like starlings and kiskadees. The birds (the vector for dispersing scheflerra throughout the island) eat the fruit and spread the seeds, islandwide, in their droppings. Because it grows quickly, schefflera is often planted by people unaware of the threat the tree poses to the island’s biodiversity. Casuarina (Casuarina equisetifolia) Well-known as the tree used to re-forest Bermuda after the loss of the cedar in the 1950s, casuarina is less well-known as a significant invasive that threatens the island’s coastline by increasing coastal erosion. Casuarina’s rapid growth, salt spray resistance and evergreen foliage seemed to make it the ideal replacement for the cedar. Moreover, it does not readily self-seed in Bermuda’s soil1. However, it does self-seed in disturbed sand and coastal rocks. The small seeds are carried by the wind and water and some are, inevitably, deposited into cracks in coastal rocks and on our beaches where many germinate and proceed to grow very quickly. Take a walk in almost any coastal area, and you’ll see casuarina seedlings springing up all over the place. David Wingate wrote in 2003 that “casuarina now threatens to become dominant on the coastline including even our beaches! Unlike the native coastal flora which grows prostrate and doesn’t obscure the vistas of the sea, the casuarina continues to grow tall and straight even in this environment. Where they are rooted in soft rock the levering effect of strong winds causes them to break off large sections of cliff, thus hastening coastal erosion.” Today, casuarina is rapidly taking over the coastal habitat and, from the water, large white areas of coast (the result of recent cliff falls) are becoming a more common sight. Staff have begun to remove scheflerra and casuarinas from the BAMZ property and are replanting with more suitable, non-invasive plants.

Several ongoing projects have given staff the opportunity to practice their teamwork by making improvements to animal exhibits. Fortunately for us we have the help of interns, and dedicated volunteers, who take care of animal husbandry and help with behavioural enrichment and diet preparation as needed. Binturongs Our two male binturongs, Kuma and Sakura, are eagerly anticipating some new exhibit furniture to scratch up and scent mark. The complete restructuring of an enclosure is a great way to keep an animal’s surroundings fresh, and this inevitably stimulates an increase in activity. Head keeper Robin Marirea is busy with new plans for the area which will satisfy the species’ needs. Binturongs, or Asian bearcats, spend much of their time in the wild moving about slowly in dense forest canopy. Because of their frugivorous (mainly fruit) diet they are considered important seed dispersers but deforestation in their native Asia has unfortunately caused bearcat numbers to fall. Training and Enrichment Committee The newly formed BAMZ Training and Enrichment Committee has been lending support to the binturong enrichment programme with great success. Staff members across all departments have come together to form a committee dedicated to the psychological well-being of our animals. Monthly meetings and Kuma and Sakura brainstorming sessions are helping to keep this important our binturongs (Arctictis binturong) area of animal care a top priority. Volunteers are crucial in the observation part of the process having spent several hours recording all activity observed in a selected exhibit every five minutes. The catalogue of behaviours, referred to as an ethogram, help to determine what type of enrichment or training plan is most suitable for that animal. Kuma and Sakura particularly enjoy finding delicious grapes and figs hidden throughout their exhibit as part of their enrichment programme. Our goal in this example was to stimulate natural foraging behaviour but the options available to us are wide ranging from sensory, foraging, structural or manipulating, just to name a few.

Given several days warning there was plenty of time to batten down the hatches and ensure the safety of our inhabitants. The animals, oblivious to the weather warnings, were wise to the impending danger as their strange behaviour suggested. Unlike most people, animals are finely tuned in to fluctuations in barometric (air) and hydrostatic (water) pressure and any major changes will activate a series of survival mechanisms. At BAMZ, the flamingo flock grew tighter and parrots sought shelter in low lying Parrots sought shelter in low lying areas areas. Some mammals like the binturongs grew defensive and acted erratically as the pressure dropped. Were they predicting disaster? It’s a common believe in many parts of the world that animals have forecast imminent threats like earthquakes long before people, though the science behind this phenomenon has yet to be understood. Reptiles Being cold-blooded, or ectothermic, reptiles become more active during the summer months as temperatures rise. This means turning off the heat lamps they require over winter and increasing their weekly diet that usually consists of rodents. The endangered radiated tortoises can now be found cohabiting with the ring-tailed lemurs after having spent the cooler months inside. These four juveniles have been growing up in the Zoo since they came to us three years ago. Providing them with a special herbivore diet and correct reptile care will help them to reach a maximum 16 inches and 35 pounds. Recently the tortoises were given an annual health check from Aquarium and Zoo curator, Dr. Ian Walker. For most animals this involves a brief sedation followed by a physical examination. Faecal samples reveal any intestinal parasites and often an X-ray is taken. Once a clean bill of health is declared the patients are returned to their exhibits after a short recovery period. We hope our radiated tortoises will live happily to a complete lifespan of forty years. Be sure to look out for our team of encounter animals: Stimpy, the blue and gold macaw; Chico, the crested gecko; Sigma, the boa constrictor and Atticus, the ball python! These are the animals that love to come outside and interact with visitors who walk through the Zoo. Being this close to an exotic animal and learning something new always seems to leave a lasting impression. We wish to say a big thank you to all of our trusted zoo volunteers and interns. This month we are sad to say goodbye to Ben Outerbridge and Lauren Vincent. We wish them all the best and hope to see them again soon in the Zoo.

Craig Schneider (Trinity College) and Chris Lane Dalhousie) have been coming to Bermuda to study algae. Craig began his work as a graduate student with Dr. Rick Searles in 1970 (Duke University) and made his first trip to the island in 1983. Chris Lane, who was Craig’s undergraduate student in the late 1990s, went on to earn his Ph.D. at the University of New Brunswick under Dr. Gary Saunders. The two have worked together on the study of Bermuda’s algae since 1999. I began working with Craig when I joined the Marine Operations team in 1997. Although I have learned plenty about algae I can’t say that I share their enthusiasm for these marine plants. To me algae are what you move out of the way in search of more interesting creatures, such as fish! are the autotrophic (food making) component of plankton. Plankton is the foundation of many aquatic food chains, supporting an abundance of animals from the tiny hogmouth fry (Anchoa choerstoma) to whale sharks (Rincodon typus). The larger macro-algae are what the ‘algae guys’ work on. So what are algae, and why are they so important that someone would devote a large portion of their life to studying them? Algae are a diverse group of simple to complex organisms. Like most plants they are able to utilize sunlight to make their own food through a process known as photosynthesis. There are two general classifications of algae: micro-algae (that which is only visible through a microscope) and macro-algae (that which is visible to the naked eye). Micro-algae Since Craig has been coming to the island, he has found a number of new genera and species, and many taxa not previously recorded in Bermuda; over seventy-five in number. Chris Flook, our collector of specimens has helped him to locate many of these species. Chris is renowned for his extraordinary knowledge of Bermuda’s marine environment and his uncanny ability to seek out and capture almost any specimen requested. It is because of his invaluable input that Craig and Chris have named one of the three new species in their latest submission to the journal Phycologia after him, Botryocladia flookii. This species is a member of the genus commonly known as sea grapes and the new one will simply be called Flook’s sea grapes. It appeared in several Aquarium display tanks in February 2008, along with the other two new species of Botryocladia—B. bermudana and B. exquisita. Take a look and find sea grapes in our displays!

In the tour guiding world, the term takes on a different and more subtle application as the guide’s duty to the recipient is to excite the senses and convey a depth of understanding that will linger well beyond the experience and, ideally, radiate outward to friends and family. As we know in life, not all things are as simple as they may seem and, characteristically, there is complex meaning to the actions and behaviour of all the earth’s inhabitants. Tour guides, who interpret exhibits whether they are living or inanimate, help to identify and explain the reasons for the actions as we know them, supported by the ever evolving body of scientific research. There are creative and engaging methods to communicate knowledge by way of artistic representation in music and live performances where a learning lesson can be embedded within the entertainment factor. Responsible animal encounters or nature theatre also provides an opportunity for people to conquer their fears and approach animals in a more realistic and calm state of mind. The visitor then walks away with a more pleasurable experience burned into their memory rather than simply strolling through the exhibits without an interpretive guide to amplify the occasion. Here at the Aquarium, Natural History Museum and Zoo you can join in the fun of the: North Rock Diver-in-the-Tank (1:10 pm) and Harbour Seal Feeding (1:30 pm daily from April through September). Check us out on Tuesdays and Thursdays for a Ring-tailed Lemur Feeding at 12:00 noon, Tuesdays a Tortoise Encounter at 12:30 pm and Thursdays a Ball Python Encounter at 2:00 pm. 12 Keep an eye out for our Critter Carts in the Aquarium and Caribbean exhibit areas featuring touchable specimens and cool facts… did you know, the ocean sunfish (Mola mola) is the heaviest known bony fish in the world, can grow 800 lbs. in little over a year and has an average adult weight of 2,200 lbs? Delight, too, in our interactive exhibit fun in the Natural History Museum. We also offer facility and behind the scenes tours per request along with eco-tours to our island’s distinctively charming, natural gems — the ones we need to protect!

The conference theme was “A Climate for Change.” Both students’ attendance at the conference was sponsored by BZS through the Ernest E. Stempel Foundation. Interested Primary 6 student delegates (aged 10 and 11) who attended “The Power of One” Environmental Youth Conference were invited to fill out an application form and write an essay that included research information on the city of Stavanger, as well as a convincing appeal as to why they should be selected to attend. I am l to r: Bermuda representatives: Noah Beek and Jahmali Bridgewater thrilled that Jahmali and Noah were chosen and am confident that they will represent Bermuda well at this conference. The aim of the conference, according to UNEP, is to increase children’s understanding of environmental challenges, to demonstrate new ideas, to allow children to express opinions, and inspire them to think globally and act locally. In Norway, the conference headquarters will be at the University of Stavanger, in the Scandinavian city voted the “European Capital of Culture in 2008.” Activities over the five days will include workshops, group discussions, and educational visits to nature reserves, museums, and other cultural sites. Finally, participants will create a wish list of challenges that will be sent to world leaders through the United Nations. This marks the fourth UNEP conference attended by Bermudian students through the BZS and the Stempel Foundation. Delegates attended similar events in Brighton, England in 2000, Victoria, British Columbia in 2002, and New London, Connecticut in 2004. “I would like to take this opportunity to thank Mr. David Hamshere of the English Sports Shop for graciously sponsoring the official delegate attire for this conference”.

Bermuda has always been conscious of its delicate ecobalance. Some of the first laws restricting the introduction of nonnative species date back to the early 1600s. So far we have managed to ‘dodge the bullets’, but times change. I have been collecting fish and keeping fish tanks since I can remember. I always wanted to find new and exotic species to display and study. Some of the Pacific species seemed so beautiful and different and completely unattainable. Bermuda’s ban on importation of live marine species prevented me from having any of these foreign critters. One species always caught my eye, the lionfish. Beautiful, poisonous and easy to keep — a young boy’s ideal pet! Times change, however, and now I no longer desire these devastating invaders. The Atlantic is in trouble and, yep, humans are responsible. Two species of lionfish (Pterios volitans and P. miles) from the Indo-Pacific region have established themselves in the Atlantic. The pet shop trade is the big culprit. 16 Some 750-thousand lionfish are imported every year into Florida alone. Accidental releases from hurricanes and owner’s “Oh, it’s only one” mindset when releasing pets into the ocean that have outgrown their tanks, have thrown the Atlantic into turmoil. The earliest reports of lionfish seen in the Atlantic go back to the late 1970s. However, one or two fish probably were not enough to establish a breeding population. As more have been released we have now passed the point of no return. There are several other species of fish that are becoming more and more common in the Florida area, and unless we can stop this unacceptable behaviour of juggling species around the world, more will come. Lionfish pose a real threat to the Atlantic. They are at the top of the food chain and breed unbelievably fast. Recently I was invited to team up with a group of scientists and environmentalists on two expeditions to the Bahamas, to study the effect of these devastating predators — and what I saw left me speechless. In the constant warm conditions of the Bahamas, female lionfish dump about thirty-thousand eggs into the sea every month! Within one year these offspring begin breeding themselves. Compare that to three to five years for native coneys, graysbys and hinds, and twenty to thirty years for groupers. Lionfish will eat anything that moves. They particularly favour cleaning stations where, with little effort, they stuff themselves with local fish. Sharks, groupers, moray eels and other apex predators won’t eat them. This has left some areas in Nassau, Bahamas with the lionfish being the dominant fish on the reef! The only way lionfish could be worse is if they grew to six feet long. In their natural environment of the Indo-Pacific, thousands of years of experience has caused the prey fish to develop a sense of respect for these indiscriminate eaters. Lionfish have to work a lot harder for their food than with the naive juveniles of the Atlantic. Their population is exploding at an incredible rate and some countries are very concerned. The Bahamian government sees lionfish as a real threat to their commercial fishing industry. Lionfish are here to stay and the Atlantic will, (it’s just a matter of time), lose certain vulnerable species. Nothing is off their menu. Shrimps, crabs, fish and even moving fragments of algae have been observed sliding down the throat of a gluttonous lionfish. Enough ‘doom and gloom’! BAMZ, in partnership with the Department of Environmental Protection, has undertaken a bold and inspiring approach to this potentially devastating invasion. At this point Bermuda is behind in the invasion, but definitely ahead on management. Special licences have been created and issued to help learn more about these fish and to potentially manage their population. Three major factors are without a doubt in our favour: “To inspire appreciation and care of island environments” bermuda natural history news Our Size: 200 square miles of reef platform is a relatively small area to manage, compared to the east coast of the States, or even the Bahamas, which have 100-thousand square miles of reef platform. Resources: Many more people have boats and many divers and fishermen (both commercial and recreational) are out on the water on any given weekend in relation to our size. Seasonal Temperature Variation: Our winter temperatures get cool enough to stop lionfish from spawning all year, as compared to the constant warm temperatures in the Caribbean. equipment to catch these unique and greedy creatures. We will never eradicate them, however, if we can successfully keep them out of known nursery areas, we might have species other than the lionfish in the future. This could play a huge role in the future, where fisheries and tourism are concerned. If you see a lionfish, please report it to lionfi[email protected] or 293 4464 ext. 820. Do not touch or harass these fish! Their venom is carried in their spines. I have been stung twice and I can tell you it is very painful. The pain rages for about an hour and the swelling is instantaneous. It took about two months for the swelling to settle down, and now, six months I cannot stress enough how serious this issue is.

They have cleaned out most of the smaller species of fish on certain sites and their range is constantly expanding. later, I am still having some complications with the infected area. If stung, place the wound in hot (not scalding) water and soak for as long as possible. Seek medical attention. Note: the venom remains potent for several days after lionfish are dead. Children, elderly people and those allergic to bee stings should take particular care. Lionfish have been found in very shallow water and will take up residence just about anywhere. “To inspire appreciation and care of island environments” Chris Flook Collector of Specimens & Lionfish Project Leader Other Photos: Chris Flook & Debbie Boyer 17 enviro-chat Clothing gets the eco-friendly makeover! Clothing is part of all our lives, whether we’re fashion conscious or purely practical. Clothing is a product that has a very high impact on the environment. The best way to lower the impact clothing has on the environment is to reduce, reuse and recycle! Reduce the amount of clothes you buy, Reuse clothes by shopping at The Barn and other second-hand or vintage stores, and Recycle by donating your unwanted clothes. How should we go about choosing eco-friendly clothing? What if a clothing label gave us information on the environmental, social and ethical impact that garment was having? Our decision making process would be so much easier! The good news is that many retailers are waking up to the idea that their consumers, given the choice, will buy eco-friendly clothing. Clothing is beginning to be marketed as eco-friendly, fair trade and green. Here’s how to ensure you are purchasing eco-friendly clothing Try to avoid clothing made from acrylic, nylon and other synthetic fibres. All of these contain plastic which could have toxic effects. Choose organic cotton as opposed to regular cotton. Organic cotton farmers don’t use pesticides and the dyes are generally less toxic. Look for clothing made from eco-friendly fibres such as hemp, jute, ingeo, calico, hessian cloth, recycled polyester, bamboo fibre, tencel, ramie, organic wool, organic linen, FORTREL ecospun, milk silk, soy silk, nettle fibre and even spiderweb fabric! Don’t be tempted to purchase no-iron cotton fabrics as these fabrics are often treated with formaldehyde finishes. No-iron fabrics should always be washed before wearing to remove excess finishes. As well as the fabric used to make clothes, many clothes are dyed and/or have laminate finishes. Clothing dyes pollute our waterways. Make sure you are purchasing ecofriendly finishes and dyes. Look for clothing that has not been manufactured in sweatshops. This can be difficult as there is very little monitoring. Some retailers are beginning to carry and advertise fair trade lines of clothing. As we become increasingly aware of the importance of purchasing eco-friendly clothing, demand will increase and retailers will respond with increased product lines and eco-friendly clothing will replace the unsustainable product lines.
