IUCN finds ocean oxygen levels dropping at record rates

Marine life is in serious trouble if ocean oxygen levels continue to plummet. A new report by the International Union for Conservation of Nature (IUCN) reveals that ocean oxygen levels have decreased by about 2 percent since the middle of the 20th century, and continued deoxygenation will put wildlife and human survival in danger. The report, which involved work from 67 scientists in 17 countries, was released Saturday at the COP25 UN Climate Change Conference in Madrid. “Urgent global action to overcome and reverse the effects of ocean deoxygenation is needed,” said Minna Eps, director of the IUCN Global Marine and Polar Program. “Decisions taken at the ongoing climate conference will determine whether our ocean continues to sustain a rich variety of life, or whether habitable, oxygen-rich marine areas are increasingly, progressively and irrevocably lost.” Related: IPCC landmark report warns about the state of the oceans, polar ice content and the climate crisis Both the climate crisis and nutrient pollution cause ocean deoxygenation. Nutrient pollution includes nitrogen from fossil fuels and run-off from agriculture and sewage. This depletes oxygen by encouraging too much algae growth. However, scientists have recently realized that rising ocean temperatures are also lowering ocean oxygen levels. Scientists say that these higher temperatures are probably responsible for about half of the oxygen loss in the ocean’s top 1,000 meters, which is the highest in biodiversity . While reversing nutrient pollution is relatively easy, reversing oxygen loss from climate change isn’t. “To curb ocean oxygen loss alongside the other disastrous impacts of climate change, world leaders must commit to immediate and substantial emission cuts,” Dr. Grethel Aguilar, acting director general of IUCN, said in a tweet. Larger fish that require more energy, such as tuna, sharks and marlins, are especially threatened by dropping ocean oxygen levels. Changing oxygen levels have already pushed them closer to the surface, where they face greater risk of overfishing . Recent massive fish die-offs may also be caused by oxygen loss. Scientists predict that lowered ocean oxygen may have far-reaching effects, such as changing the Earth’s phosphorus and nitrogen cycles on land. + IUCN Via EcoWatch Image via Jeremy Bishop

Aluminum cans vs plastic bottles: which is best for the environment?

Comments Off on Aluminum cans vs plastic bottles: which is best for the environment?

We’ve all been guilty of buying an unsustainable beverage every once in a while, but when faced with the perplexing conundrum of whether to grab that plastic bottle or aluminum can, which do you believe to be more environmentally-friendly ? The history of plastic goes back to the early 1900s when the first fully synthetic plastic was invented as an alternative to the shellac used in electronic insulation. During World War II, plastic production increased by 300% in the United States as it was used for everything, from nylon in ropes and parachutes to plexiglass in airplane windows. After the war, commercial use of plastic had completely taken off and incorporated into virtually every product and market in modern life. By the 1960s, the first occurrence of plastic pollution in the oceans was recorded. Related: This rechargeable camping headlamp is made out of sustainable wood and recycled aluminum Today, the Environmental Protection Agency estimates that 80% of the marine debris found in our oceans originated as land-based trash that was not recycled. Over 90% of the plastics found in the ocean is comprised of microplastics, which commonly end up ingested by aquatic animals, often killing them through choking or toxicity. The National Geographic Society found that 91% of the world’s plastic was not recycled in 2018. That alarming statistic means that all but 9% of plastic waste ends up either in landfills or in the ocean. Plastic bottles are made from petroleum, or “crude oil.” Oil drilling, also known as fracking, wastes water, releases methane into the atmosphere, produces oil spills and generally wreaks havoc on the environment. Plastic bottles are typically too thin to recycle into more plastic bottles, but the material can be made into fibers for things like carpets, clothing and sleeping bags. In 2018, the recycling rate for plastic bottles was just over 29%. The use of aluminum cans was first introduced to the general public in 1959 by Coors. About five years later, Royal Crown Cola brought aluminum into the soft drinks game with their RC Cola and Diet Rite. Since then, they’ve been used for everything from energy drinks and sparkling waters to sodas and wine. Aluminum offered an affordable alternative to steel as well as a more convenient surface for company printed text and graphics. Aluminum cans can be recycled into more cans in a true “closed-loop” recycling process. In 2018 the recycling rate for aluminum cans was 49.8%. The liquid inside the aluminum can benefit from the material as well, since aluminum blocks light, moisture and oxygen from permeating the outside. This makes the drinks more sustainable , as they have a longer shelf-life. Lightweight cans have only decreased in weight over the years, with the first aluminum cans weighing about three ounces per unit and modern cans weighing less than half an ounce. Typically recycling programs value aluminum over plastic or glass, with the former holding $1,317 worth of value per ton of recyclable material versus plastic’s $299 per ton. This allows more municipal recycling programs to stay in service. IFC International, a global management consulting and technology company, found in a 2016 study that the greenhouse gas emissions associated with the transportation and refrigeration of aluminum are 7 to 21 percent lower than that of plastic and 35 to 49 percent lower than glass. The easy-to-recycle aluminum material doesn’t stop there; the shiny stuff’s strength is another advantage. According to the Aluminum Association , four six-packs can hold up a two-ton vehicle thanks to the packaging’s aversion to rust, corrosion and ability to withhold carbonation pressure. This stamina allows companies to package and transport more product using less material. Related: Prada jumps into the sustainability realm with six Re-Nylon bags made from recycled plastic waste When it comes to the amount of recycled material found in cans versus plastic bottles, aluminum has the upper hand, as well. In 2016 the Environmental Protection Agency found that aluminum cans contain three times the amount of recycled content than plastic. They also estimated that aluminum cans are made up of 73% recycled material on average.  Aluminum doesn’t occur in nature and is primarily comprised of bauxite rock, which is primarily found in Australia, India and Brazil. Collecting bauxite comprises of open-pit mining, which usually involves moving or bulldozing large amounts of vegetation and surface rocks. This type of mining negatively affects ecosystems and creates air and water pollution , which can cause health issues for wildlife and humans. Not to mention, the combination of electrolysis and chemical processing that it takes to turn bauxite into conventional aluminum takes a large amount of heat and energy. However, the Aluminum Association assures that land conservation has become an important focus among bauxite mining. Topsoil from the site is stored to be replaced after the process is finished, so “an average of 80 percent of the land mined for bauxite is returned to its native ecosystem.” So how can you make sure you’re not contributing to plastic or aluminum pollution? Always reach for that reusable water bottle before going out! Fill it with water, soda, juice or whatever you like.

Adidas continues drive toward sustainable manufacturing with FUTURECRAFT.LOOP performance shoe

Comments Off on Adidas continues drive toward sustainable manufacturing with FUTURECRAFT.LOOP performance shoe

It’s not everyday a household name brand in the performance footwear industry announces a 100 percent recyclable shoe, fortunately for conscientious consumers and the planet, adidas has developed the FUTURECRAFT.LOOP performance running shoe, designed to tackle the daily pavement beatings like other shoes across the brand. However, the difference is that instead of heading to landfills with hundreds of thousands of other shoes, the FUTURECRAFT.LOOP can be returned to Adidas where it is broken down and reused to create new performance running shoes. “Taking plastic waste out of the system is the first step, but we can’t stop there,” said Eric Liedtke, Executive Board Member at Adidas, responsible for Global Brands. “What happens to your shoes after you’ve worn them out? You throw them away – except there is no away. There are only landfills and incinerators and ultimately an atmosphere choked with excess carbon , or oceans filled with plastic waste . The next step is to end the concept of “waste” entirely. Our dream is that you can keep wearing the same shoes over and over again.” Related: These sneakers are painted with cast-off blood from slaughterhouses The process was developed after nearly a decade of research and development focused on changing age-old performance-shoe manufacturing practices. The end goal was to create a shoe that was not only sourced from recycled materials, but was also able to be turned back into another pair, creating a full-loop of manufacturing responsibility. The process involves zero waste . This dive into sustainable footwear isn’t new territory for the company who partnered with Parley for the Oceans, in 2015 to introduce a footwear concept with an upper made entirely of yarns and filaments that were reclaimed and recycled from plastic waste and illegal deep-sea gillnets in the ocean. Adidas has made recycling materials a common business practice. In 2019, they plan to manufacture 11 million shoes that contain recycled plastic collected from beaches on remote islands and coastal communities. In fact, the company has looked to the future for some time and is currently working towards a goal of using only recycled polyester for every possible application by 2024. Under a current beta program, Adidas is sending shoes to participants in several major markets who will use the shoes and provide feedback. The company will use that feedback to create the final version of the FUTURECRAFT.LOOP, due to hit the market in 2021. “FUTURECRAFT.LOOP is our first running shoe that is made to be remade. It is a statement of our intent to take responsibility for the entire life of our product; proof that we can build high-performance running shoes that you don’t have to throw away,” said Eric Liedtke. + Adidas Images via Adidas
