1 . A record surge in the creation of marine protected areas has taken the international community close to its goal of creating nature refuges on 17% of the world’s land and 10% of seas by 2020, according to a new UN report. Protected region snow cover more than five times the territory of the US, but the authors said this good news was often undermined by poor enforcement. Some reserves are little more than “paper parks” with little value to nature conservation. Atleast one has been turned into an industrial zone. More than 27m square kilometres of seas (7% of the total) and 20m sq km of land (15% of the total) now have protected status, according to the Protected Planet report, which was released on Sunday at the UN biodiversity conference in Sharm el-Sheikh, Egypt.
Almost all of the growth has been in marine regions, most notably with the creation last year of the world’s biggest protected area: the 2m sq km Ross Sea reserve, one-fifth of which is in the Antarctic. The no-fishing zone will be managed by New Zealand and the US.
“We have seen an enormous expansion in the past two years. There is now more marine protected area than terrestrial, which nobody would have predicted,” said Kathy McKinnon of the International Union for the Conservation of Nature. “I think we’ll continue to see a substantial increase, I’d guess, to at least 10% in the near future.”
The UN convention on biological diversity says it has received national commitments for an additional 4.5m sq km of land and 16m sq km of oceans to be given protected status in the next two years. This would put it on course to achieve one of the key aims of the 2010 Aichi biodiversity targets.
“This is the target with the most progress. In an ocean of bad news about biodiversity loss and eco-destruction, it is important to highlight that progress, though we still have a lot more to do to ensure not just the quantitive target but the effectiveness of the management,” said CristianaPașca Palmer, the head of UN Biodiversity.
The creation of protected areas has not been enough to halt a collapse of species and ecosystems that threatens civilisation. Since 1970 humanity has wiped out 60% of mammal, bird, fish and reptile populations, with a dangerous knock-on impact on food production, fisheries and climate stability.
Protected areas are important refuges from this wave of extinctions but many are underfunded and poorly policed. Only one in five have provided management assessments to the UN, which has raised questions about the viability of the rest.
Naomi Kingston, of UN environment world conservation monitoring centre, said: “There is a race to deliver on Aichi target 11. It is fantastic that countries are coming with more ambition, but not if it is just a number without substance.
“Some areas that have been reported to us as protected areas have been completely built over. We need datasets to define which areas are paper parks and which are real.”
Developing nations have better reporting standards because many are obliged to provide regular assessments in order to qualify for funds from the Global Environment Fund. By contrast, many wealthier nations devote few resources to monitoring.
Discussions will focus on a new, more flexible category for community land that is used by locals for both agricultural production and wildlife conservation. In Africa, Asia and Latin America, this is a model that has often helped improve biodiversity because residents — often from indigenous communities — live closely with nature and have an interest in protecting it.

3 . When a heavy storm hit, residents of the floating community of Schoonschip in Amsterdam had little doubt about whether they could ride it out. They tied up their bikes and outdoor benches, and checked in with neighbors to ensure everyone had enough food and water as their neighborhood slid up and down its steel foundational pillars (支柱), rising along with the water and going back to its original position after the rain stopped.
“We feel safer in storm because we are floating,” says Siti Boelen, a Dutch television producer who moved into Schoonschip two years ago. As sea levels rise and supercharged storms cause waters to rise, floating neighborhoods offer an experiment in flood defense that could allow coastal communities to better fight against climate change.
A floating house can be constructed on any shoreline and is able to deal with rising seas by remaining on the top of the water’s surface. Unlike houseboats, which can easily be moved and relocated, floating homes are fixed to the shore and are usually connected to the local sewer (污水管道) system and power grid. They are structurally similar to houses built on land, but instead of a basement, they have a concrete hull (船体) that acts as a counterbalance, allowing them to remain stable in the water.
Severe wind and rain, or even the passing of large cruise ships, can make the buildings rock. Siti Boelen, the Schoonschip resident, says that when she first moved in, stormy weather made her think twice. “You feel it in your stomach,” she says, adding that she has gotten used to the feeling. Floating homes also require extra infrastructure and work to connect to the electricity grid and sewer system.
But the benefits may outweigh the costs. “If there are floods, it’s expected that many people will move to higher ground. But the alternative is to stay close to coastal cities and explore expansion onto the water,” says Rutger de Graaf. “If you consider that in the second half of the century, hundreds of millions of people will be displaced by sea level rise, we need to start now to increase the scale of floating developments.”

5 . Scientists from the National University of Singapore studied how much time twins spent in natural spaces compared with each other and found that they shared a similar level of desire to be in nature.
“The reason we decided to study this in twins is that we could estimate heritability(遗传性)based on the genetic similarities in identical twins(100%)versus genetic similarities in non-identical twins(50%),” said Chia-chen Chang, who led the study. “If a trait(特性), such as the desire to be in nature, is clearly more similar between identical twins than non-identical twins, this will then suggest a trait is heritable.”
Using the TwinsUK registry, researchers surveyed 1,153 pairs of twins—identical and non-identical—about how they experienced nature. They were required to answer questions involving how frequently they visit natural spaces such as public parks and private gardens and rate their familiarity with nature. After comparing and analyzing the collected data, researchers found that identical twins were more similar to each other in their attitudes towards nature.
While previous studies have found that spending time in natural spaces improves mental well-being, this varies from person to person. For the first time, the researchers say, this study has indicated why that is by suggesting there is likely to be a genetic component in our preference for nature and our likelihood to visit natural spaces.
However, heritability declined with age, perhaps showing that environmental factors such as access to nature and green spaces bring about a love of the outdoors as one grows older. That is to say, a person's desire to be in nature and how often they experience it are influenced by both genes and personal experiences. Those who live in urban environments without access to nature could end up having a lesser appreciation of it. Hence, it's necessary that diverse urban planning is needed to provide access to natural spaces-and the benefits they offer—for all.

6 . It is a well-known fact that plastic bottles, which take hundreds of years to rot, are harmful to our environment. However, efforts by environmentalists to encourage consumers to switch to alternatives, like water fountains or reusable bottles, have not been very effective. The U.S. alone uses over 50 million plastic bottles annually, 80% of which end up in landfills.
To try to stop that, Rodrigo García González, Pierre Paslier and Guillaume Couche from the Imperial College London have been working on a revolutionary solution — water wrapped inside an eatable container made mostly from seaweed. All the customer has to do to relieve his/her thirst is pop the entire drop into the mouth.
The inventors, who have been working on the Ooho bubble since 2014, use a simple two-step cooking process called spherification (球化) to create the delicate container. They begin by dipping a frozen ball of water or juice into a chemical solution (溶液). This helps form a layer around the liquid. The ball is then absorbed in a solution made from seaweed extract. This creates a second layer, helping strengthen the structure so that the water or juice does not leak. In addition to saving our environment, the biodegradable (可降解的) packaging costs just two cents each, making it cheaper to produce than plastic.
After three years of perfecting the design, the inventors, who recently raised over 1 million USD from a financial activity, are ready to bring the Ooho bubble to local market. However, there are a few challenges that still need to be overcome before the product’s launch. In addition to getting accustomed to the taste of the covering, each eatable container contains just a mouthful of water, requiring consumers to drink multiple bubbles to relieve their thirst. There is also the issue of finding an eco-friendly packaging to transport the bubbles so that they remain clean and do not burst. Hopefully, the inventors will find ways to handle the issues so that we can reduce, or perhaps even remove, plastic bottles.

7 . Climate change leads to a threat to the world’s sandy beaches, and as many as half of them could disappear by 2100, a new study has found. Even by 2050 some coastlines could be unrecognizable from what we see today, with 10% to 12% facing severe erosion (侵蚀).
Using updated sea level rise predictions, the researchers analyzed how beaches around the world would be in a future with higher seas and more damaging storms. They also considered natural processes like wave erosion, as well as human factors-like coastal building developments, all of which can affect a beach’s health. The study found that sea level rise is expected to outweigh these other factors, and that the more heat-trapping gases humans put into the atmosphere, the worse the influences on the world’s beaches are likely to be.
It’s hard to overstate just how important the world’s beaches are. They cover more than one third of the world’s coastlines, and protect coastal areas from storms. Beaches are also important economic engines, supporting relaxation, tourism and other activities. And in some areas, the beach is more than a vacation destination. In places like Australia, life near the coast revolves around the beach for much of the year.
Some of the world’s most popular beaches are already taking action. Places like Miami Beach are trucking in thousands of tons of sand to patch up (修复) badly eroded shorelines, while others have built sea walls and breakwaters in an attempt to hold precious sand in place. But the financial and environmental costs of these projects are huge, and scientists say rising seas and more powerful storms, supercharged by a warmer climate, will make this a losing battle.
However, the researchers did find that humans have some control over what happens to the world’s beaches. If the world’s governments are able to stick to modest cuts to heat-trapping gas pollution, the researchers found that 22%of projected beach losses by 2050 could be prevented, a number that grows to 40%by 2100 if greenhouse gases are limited.

9 . Masks that helped save lives are proving a deadly danger for wildlife, with birds and sea creatures trapped in the shocking number of thrown-away facial coverings. Single-use masks have been found around pavements, waterways and beaches worldwide. Worn once, the thin protective materials can take hundreds of years to decompose. “Face masks aren't going away any time soon—but when we throw them away, these items can harm the environment and the animals,” Ashley Fruno of animal rights group PETA said.
In Britain, a gull was rescued by the RSPCA after its legs became tangled in the straps of a mask for up to a week. The animal welfare charity took it to a wildlife hospital for treatment before its release.
The biggest impact may be in the water. More than 1.5 billion masks made their way into the world's oceans last year, accounting for around 6,200 extra tonnes of ocean plastic pollution, according to environmental group Oceans Asia.
Conservationists in Brazil found one mask inside the stomach of a penguin after its body was washed up on a beach, while a dead pufferfish was discovered caught inside another off the coast of Miami. French campaigners found a dead crab trapped in a mask near the Mediterranean. Masks and gloves are “particularly problematic” for sea creatures, says George Leonard, chief scientist from NGO Ocean Conservancy. “When those plastics break down in the environment, they then enter the food chain and impact entire ecosystems.” he added.
There has been a shift towards greater use of reusable cloth masks as the pandemic has worn on, but many are still using the lighter single-use varieties. Campaigners have urged people to bin them properly and cut the straps to reduce the risk of animals becoming trapped. Oceans Asia has also called on governments to increase fines for littering and encourage the use of washable masks.

10 . Chinese scientists say they have developed a robotic fish that can remove microplastic particles from water environments. Researchers working on the project say the robots could help to clean up plastic pollution in oceans around the world.
The robotic swimmers are about 1.3 centimeters long. They are made of a soft chemical Compound. The robots are designed to absorb microplastics while moving through the water. The project was launched by a team at Sichuan University in southwestern China. The researchers said the robots have already performed well in shallow water and they plan to carry out more tests in deeper waters. The scientists reported their findings in a new study in Nano Letters. The publication comes from the American Chemical Society, a nonprofit organization supported by the U.S. Congress. The robotic fish were built to target microplastic particles, which are smaller than five millimeters. Studies have confirmed that microplastic pollution has been discovered in many natural environments. The material comes from the breakdown of manufactured plastic products and industrial waste.
The team said the robots can be controlled by light. Turning “a near-infrared light laser” on and off causes the fish’s tail to move back and forth, the American Chemical Society said. The robotic fish can swim up to 2.76 body lengths per second. The researchers said this is faster than most similar soft robots. Wang Yuyan was a member of Sichuan University’s research team. She told Reuters news agency that the small, lightweight robot is currently being used to collect microplastics for research purposes. But Wang added that the team plans to expand that use so the robot fish can remove larger amounts of microplastic waste from deep ocean areas. The fish can take in different kinds of microplastics and even repair itself when damaged, the researchers said. And if a robot fish is accidentally eaten by a real fish, it could safely digest the material, the team added. Wang said similar robots could be developed to be placed inside the human body to remove unwanted materials or disease.
