Ocean Cleaning Device Succeeds in Removing Plastic for the First Time
An enormous floating device designed by Dutch scientists for the non-profit Ocean Cleanup successfully captured and removed plastic from the Great Pacific Garbage Patch, the company announced Wednesday, as CNN reported.
Ocean Cleanup has been hard at work on creating a device to attack the plastic waste crisis for seven years, by creating a device that captures plastic in its fold like a giant arm, according to Business Insider. The company announced that it was able to capture and hold debris ranging from large cartons, crates and abandoned fishing gear — or "ghosts nets," which are a scourge to marine life — to microplastics that are as small as one millimeter, according to an Ocean Cleanup press release.
"Today, I am very proud to share with you that we are now catching plastics," Ocean Cleanup founder and CEO Boyan Slat said at a news conference in Rotterdam, as CNN reported.
The system's success in capturing microplastics came as a welcome surprise since microplastics tend to fall to the ocean floor rather than float on the surface, according to the press release. Since microplasitcs tend to sink, Ocean Cleanup focused on large pieces of plastic.
Slat posted a picture on Twitter of collected debris along side a forsaken wheel.
"Our ocean cleanup system is now finally catching plastic, from one-ton ghost nets to tiny microplastics! Also, anyone missing a wheel?" Slat wrote.

The Ocean Cleanup device is a U-shaped barrier that drops a net below the surface. As the current moves, the net traps faster moving objects that float into it. Fish, however, are able to swim beneath it, according to CNN.
Slat first presented the concept of a giant barrier near the Great Pacific Garbage Patch in a TEDx talk when he was 18 years old. But the project has been slowed by some spectacular failures that Slat and his team learned from. Last year, a design flaw stopped the barrier from holding onto the plastic it captured and a 59-foot section of the barrier disconnected from the device. In its next attempt, the design team noticed that plastic was floating over the top of a cork line that was supposed to stabilize the system, as Business Insider reported.
The team also noticed that the barrier, known as System 001/B was picking up speed from the ocean currents that outpaced the plastic litter. Therefore, after some rethinking and some upgrades, the device was slowed down by a parachute-anchor. That allows faster moving plastic to float into the barrier. After the parachute-anchor was on, the team fixed the corkline so very little plastic was able to pass over the top of the barrier, according to Ocean Cleanup's press release.
"Our team has remained steadfast in its determination to solve immense technical challenges to arrive at this point," said Slat in the statement. "Though we still have much more work to do, I am eternally grateful for the team's commitment and dedication to the mission and look forward to continuing to the next phase of development."
The Great Pacific Garbage Patch, which is twice the size of Texas, is a swath of plastic debris brought together by the ocean currents and kept in formation by a whirlpool of currents, as The Guardian reported. Ocean Cleanup now wants to scale up the project so it can hold plastic for a year before collection is necessary. It has the goal of removing half of the Great Pacific Garbage Patch.
The Ocean Cleanup said in its press release that it will now start on its next iteration, System 002, a full-scale cleanup device that will endure rough ocean conditions and retain the collected plastic for long periods of time between collections. Once the plastic is collected, it will be returned to land and processed for recycling.

Even after the world's largest economies adopted the landmark Paris agreement to tackle the climate crisis in late 2015, governments continued to pour $77 billion a year in public finance into propping up the fossil fuel industry, according to a report released Wednesday.

Southeast Asia is one of the biggest sources of plastic waste from land to the ocean, and Thailand is among the top five contributors. In January, Thailand placed a ban on single-use plastic, and was looking to reduce its plastic waste by 30% this year.
Food Delivery<p>One of the biggest contributors to the plastic problem is food delivery. As people have been housebound, their tendency to order food delivery has risen, resulting in increased usage of plastic containers and wrapping material.</p><p>Grab, a Singaporean food delivery app, saw a surge of 400% in orders. Other such apps like Line Man and Foodpanda Thailand, too, have seen a rise of 300% and 50% in their orders, respectively.</p><p>Waste from a single delivery could contain several plastic items such as containers, seasoning packets, beverage holders, chopsticks, spoons, forks and so on.</p><p>"Plastic containers for food are often contaminated, the waste separation and collection are not systematic, and there is no regulation on waste separation and enforcement," said Wijarn Simachaya, President of TEI.</p>
Waste Management<p>While countries across North America, Europe and Japan also contribute high levels of plastic waste, they have relatively efficient waste management systems in place.</p><p>The Thai government had released a "Plastic Waste Management Road Map," to phase out the use of plastic by 2030. One of the initiatives of this plan was the single-use plastic ban that has been enforced since January.</p><p>According to data released by the Department of Environment and Quality Promotion, an average person in Thailand uses about 8 plastic bags per day, which adds up to 200 billion per year.</p>
Widespread<p>Some say the pandemic has merely brought to the surface an already existing problem for the country. Experts believe that greater awareness and lifestyle changes among the masses could help address this issue.</p><p>The effects of plastic waste are long term. The pollution affects the oceans, aquatic life and also humans.</p><p>"Plastic pollution may also be contaminating the air that we breathe every day. Plastics do not biodegrade, therefore once they are introduced into an animal's system, they will stay there for a long time. Therefore, consuming these plastics leads to malnutrition, digestive blockage and slow poisoning effects due to plastic's heightened toxicity," Simachaya told DW.</p><p>While the pandemic may have been a setback to Thailand's struggle to eliminate plastic waste, Simachaya believes a change in awareness and habits will lead to a gradual decrease in plastic waste.</p><p>Thailand is slowly starting to ease lockdown rules. While it is too premature to say whether the plastic waste levels are expected to go down, some delivery outlets have started offering bio-degradable containers and cutlery. Some online shopping companies are also giving the option of receiving packages without the use of plastic.</p>

The Indonesian government has backed down from a decision to scrap its timber legality verification process for wood export, amid criticism from activists and the prospect of being shut out of the lucrative European market.
Viruses, pollution and warming ocean temperatures have plagued corals in recent years. The onslaught of abuse has caused mass bleaching events and threatened the long-term survival of many ocean species. While corals have little chance of surviving through a mass bleaching, a new study found that when corals turn a vibrant neon color, it's in a last-ditch effort to survive, as CBS News reported.
