1 . About 12 million tons of plastic wastes are entering the oceans every year. This garbage pollutes the water, kills wildlife and breaks down into small pieces that fish and other creatures eat.
Now a group of Spanish fishermen will receive economic support to catch plastics. It is part of a new project. Carlos Martin is one of the fishermen taking part in the project. He and his partners collect the plastic in the ocean and bring it back to land every week. Martin thinks rivers carry a lot of plastics to the sea. He says his most concern is no more than that the plastics often get caught in the nets, which makes nets not work properly. They take on mud（泥）, causing the nets to break because they weigh so much.
Under the new programs, one million pounds will support ocean cleanup efforts for fishermen like Martin. The money is coming from the European Union and the Catalan government. Sergi Tudela, the General Director of Catalonia Fisheries, is responsible for the cleanup project. He said, "We are hopeful that if we are successful in this project, we can apply it to other areas in the Mediterranean（地中海）."
Government reports show that the amount of plastic wastes washing up along the Spanish coastline has grown by 65 percent in just six years. Fishing equipment makes up a large part of the about 8 to 12 million tons of plastics left in the world's oceans every year.
Martin says the fishing community now understands how big the problem is. He says, "In the past we didn't see it that way. We took the plastic garbage and threw it back into the water. I think that after a few year here we have realized the problem. Nothing is thrown into the water; we collect everything and bring it to shore.

2 . Micro-plastics have occupied almost every part of the planet today, including the most distant reaches.
The Arctic is far from clean, though it s rarely stepped in by visitors. Melanie Bergmann, a marine ecologist (海洋生态学家) and her colleagues had been studying plastics on the Arctic seafloor since 2002. In deep sea, they found about 6,0000 particles (微粒) in every 2.2 pounds of mud. In sea ice, there were as much as 12,000 pieces per 34 ounces of melted ice.
Scientists measured micro-plastics in snow from this distant location and found a lot, which could only have caught rides on the wind. The study raises concerns about the pollution that micro-plastics brought to the air, bringing a health risk to people and animals that breathe them in. But they are less worried about the threat that breathed-in pollutants have to wildlife than about polluted snow going into water.
The science on the health effects of micro-plastics is still going on.“For human health, we now now very little," says micro-plastics researcher Chelsea Rochman, “There is a lot of concern. For wildlife, we know that micro-plastics may go into every level of the food chain." Laboratory studies find some physical and chemical effects from micro-plastics, but the findings vary by the plastic type, shape experiments will be carried out soon with use of equipment if financial support approves."
Even worse is the threat from airborne micro-plastics in the area---too small to be noticed and may actually enter cells. Research on that also has been done and it could be a bigger problem, according to Rochman.

3 . On November 7, Lewis Pugh completed a one-kilometer swim in the freezing waters of King Edward Cove, off South Georgia in Antarctica. He was wearing only his swimming glasses, cap and Speedo !
Pugh is an advocate for our oceans and seas, working to protect these ecosystems with their large diversity of marine life. When asked why he doesn't wear a wetsuit(防寒泳衣), Pugh says, "I ask world leaders to do everything they can to protect our oceans. Sometimes the steps they need to take are difficult and unpopular. If I'm asking them to be courageous, I must also be. Swimming in a wetsuit would not send the right message."
It took Pugh about 19 minutes to complete the one-kilometer swim in Antarctica where the water averaged about 1.6 degrees Celsius. He says that his body can only tolerate about 20 minutes in the freezing waters before it starts shutting down. As he swims, his body temperature steadily drops, which in turn causes his muscle control to drop, slowing him down. When he is done with his swim, his support team rushes him to a hot shower and it takes almost an hour for his body temperature to return to normal.
Doctors and Pugh caution that one must receive months of training to swim in such cold waters. Even expert swimmers who are unused to freezing water can drown within minutes because of the physical shock experienced by the body. Pugh says he trained for six months before this swim.
This is not the first time that Pugh has swum in dangerous conditions. In 2007, he swam one kilometer in the North Pole to draw attention to the melting Arctic ice due to climate change. In 2015, he swam in the Bay of Whales in Antarctica's Ross Sea as part of his successful campaign to help set up a marine reserve there.

4 . NOT that long ago, the world wondered whether clean energy could survive without government support. Now the question is how far it can spread. The number of electric vehicles. which was about 1 million in 2015, last year reached 2 million. In electricity generation, too, trend is with the greens. In the first half of this year wind, solar and hydro generated a record 35% of Germany's power.
Greater success is breeding greater ambition. California is proposing to reach 60% renewable energy by 2030: 176 countries have clean-energy goals. Hawaii, America's most oil-dependent state, has promised to be 100% renewable by the middle of the century. So have 48 poor countries vulnerable to climate change. This week the number of multinationals making a commitment to running their operations on 100% renewable energy rose to 100.
But not every target is helpful. To see why, consider that goal of 100% renewable energy. It makes solving climate change seem easy. In fact, though wind and solar can generate the whole country's electricity some day, renewables still account for less than 8% of the world's total power output. Moreover, cleaning up electricity is only part of the battle. Even though gas-fired heating and cooking can be at least as big a source of greenhouse-gas emissions, renewable heating gets little attention. Transport policy is unpredictable, too. Carmakers may hit their goal of annual sales of 10 million electric vehicles in a decade, but battery-powered road transport, shipping and aviation are dreams. A much-quoted claim that America could rely on wind, solar and hydro alone for its electricity has recently been bitterly criticized by a group of respected academics.
Most importantly, a 100% renewables target confuses means with ends. The priority for the planet is to stop net emissions（净排放量）of greenhouse gases, especially carbon dioxide. Putting too much emphasis on wind, solar and other renewables may block off better carbon-reduction paths. After decades of investment, it is wrong to leave nuclear power off the table. Carbon emissions in Germany actually rose because it chose to phase out nuclear power gradually and so burned more coal. New technologies, such as "direct air capture" systems designed to separate carbon dioxide from the air, may in time prove vital. Likewise, greater energy efficiency could reduce emissions by even more than using renewables would.

5 . China’s war on garbage is as digital as the country itself. Think QR codes attached to trash bags that allow the government to trace exactly where its trash comes from.
On July 1, Shanghai began a compulsory garbage sorting program. Households and companies must classify their wastes into four categories and dump them in appointed places at certain times. The strict program became a headache for some residents. Not even the most environmentally conscious person can get all the answers right. Like, which bin does the newspaper you just used to pick up dog poop (粪便)belong to?
Gratefully, China’s tech startups are here to help. For instance, China’s biggest internet companies responded with new search features that help people identify what wastes are “wet”, “dry”, “toxic”, or “recyclable”. Simply pull up a mini app on WeChat, Baidu or Alipay and enter the keyword. The tech firms will give you the answer and why.
Alipay, Alibaba’s electronics payment company, claims its garbage sorting mini app added one million users under just three days. The mini app has so far indexed (编索引) more than 4,000 types of rubbish. Its database is still growing, and soon it will save people from typing by using image recognition to classify trash when they snap a photo of it. If people are too busy or lazy to hit the collection schedule, well, startups are offering trash service at the doorstep. A third-party developer helped Alipay build a recycling mini app and is now collecting garbage from 8,000 apartment complexes across 11 cities. To date, two million people have sold recyclable materials through its platform.
Besides helping households out, companies are also building software to make property managers, life easier. Some residential complexes in Shanghai began using QR codes to trace the origin of garbage. This way, regulators in the region know exactly which family has produced the trash and fine violators.

6 . Reducing plastic waste isn't easy because the cheap material is found in almost every household item. Now, a delicious and nutritious solution has come up to help reduce our dependence on this environmental hazard.
David Christian, the co-founder of Evoware, says the idea of creating the biodegradable (生物降解的) products came from concern at the country’s high pollution rate. Indonesia is home to four of the world's worst polluted rivers. Since single-use packaging is a large contributor to the problem, Evoware decided to deal with that first.
After investigating various materials, the company settled on seaweed. Unlike corn, commonly used for biodegradable containers, seaweed does not require resources like water or large amounts of space. Since Indonesian farmers already harvest more seaweed than they can sell, it's easy for the company to find the material.
Though they will not reveal their production process, Evoware says the seaweed packaging contains no chemicals and is safe to consume. The company has also invented single-use cups, which can break down 30 days after they're thrown away.
While replacing plastic with the seaweed products may seem appealing to most of us, it is a hard-sell in Indonesia. According to Christian, ''The awareness to reduce single-use plastic is still very low. This makes our bioplastic unnecessary.” Also a factor is the cost, which is higher than using plastic. Hopefully, Evoware will succeed in convincing Indonesians and people worldwide that switching to their products will be helpful to protecting our beautiful planet.

8 . More than half of the birds in Washington are at risk of extinction because of climate change. That's according to a new national report from the Audubon Society, which gives detailed analysis of climate effects on about 600 species of North American birds.
It's based on more than 140 million observations of birds across the US, Mexico and Canada. Audubon scientists looked at the likely effects of sea-level rise, urbanization, drought, extreme spring heat, increased fires, heavy rain and other factors.
But it doesn't just spell out a doomsday scenario (世界末日).Instead, it offers a range of effects and warming, depending on how much carbon humans add to the atmosphere.
"It is truly an existential threat (威胁), not only to birds but to people,” said Doug Santoni, board chair of Audubon Washington, who looked into the report as soon as it came out.
Santoni says he was struck to see the vulnerability (脆弱)of a common “ backyard bird" , the dark-eyed junco. It's one that many first-time birders become familiar with as they learn how to identify species based on their markings and other traits. Currently in Washington, you can count on juncos to show up at your feeder, year round. Extreme spring heat, increased fires and heavy rain are the kinds of changes that will force birds like these north, or kill them off if they fail to adapt.
Trina Bayard, director of bird conservation at Audubon’s Washington chapter, says, "It's certainly a very serious warning report," but adds that there’s still hope. “If we can stabilize current temperatures and decrease our emissions (排放), we can really reduce the effects to these birds …that's very motivating. ”

9 . The replacement of fossil and nuclear energy sources for electricity production by renewables such as wind, sun, water and biomass is a cornerstone of Germany’s energy policy. Amongst these, wind energy production is the most important component. However, energy production from wind is not necessarily ecologically sustainable. It requires relatively large spaces for installation and operation of turbines, and bats and birds die after collisions with rotors in significant numbers. For these reasons, the location and operation of wind energy plants are often in direct conflict with the legal protection of endangered species. A recent survey on this green-green dilemma among over 500 representatives by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) concludes that the current mechanisms for the protection of bats in wind power projects are insufficient.
“We found broad consensus among participants,” states Christian Voigt, first author of the survey. “The overwhelming majority of respondents considered the protection of biodiversity to be just as important as the contribution to protect the global climate through renewable energy production.” Most stakeholders agreed that small to moderate losses in the yield of wind power plants in terms of electricity production caused by the consistent application of conservation laws must become acceptable. However, significant discrepancies also existed. For example, representatives of the wind energy industry considered compliance with climate protection targets as more important than measures to protect species.
The conflict between wind power projects and the objectives of biological conservation intensified in recent years because the rapidly rising number of wind plants – there are now around 30,000 on mainland Germany – has made suitable locations scarce. “Besides, only about 25% of wind turbines are operated under mitigation schemes such as temporary halt of wind turbine operation during periods of high bat activity even though the legal framework would require the enforcement of such measures,” adds author Marcus Fritze of Leibniz-IZW.
For the purpose of this survey, the authors selected bats as a representative group of species for all wildlife affected by wind turbines, as large numbers of bats die at turbines and they enjoy a high level of protection both nationally and internationally, and therefore play an important role in planning and approval procedures for wind turbines. The results of years of research led by Voigt at the Leibniz-IZW show that fatalities at wind turbines in Germany affect bat populations in Germany as well as populations in other European regions from where these bats originate.
On the basis of the survey results, the authors argue in favour of a stronger consideration of nature conservation objectives in the wind energy industry. They suggest ways in which the cooperation of those involved in wind power projects can be improved so that both wind energy production and the goals of biological conservation can be satisfied.

10 . Scientists say they have found high levels of small plastic particles(颗粒) in Arctic snow. A German-Swiss research team collected snow samples(样本）from the Arctic and other areas. They included northern Germany, the Bavarian and Swiss Alps, and the North Sea island of Heligoland.When the researchers examined the samples in a laboratory, they were surprised to find very high levels of microplastics.
Microplastics are very small pieces of plastic. These plastic particles are generally smaller than 5 millimeters in length. They come from the breakdown of man-made plastic products and industrial waste.
The study found the highest levels of microplastics came from the Bavarian Alps. One snow sample from the area had 154,000 microplastic particles per liter. Samples collected from the Arctic had much lower levels. However, even samples from the Arctic contained up to 14,000 particles per liter.
The study also attempted to explore how some of the material could have been carried in the atmosphere. A limited number of earlier studies did find microplastics in the air of some cities, including Paris, Tehran and Dongguan, China.
Bergmann Melanie co-wrote the report on the new study. She believes the new study clearly shows that “the majority of the microplastic in the snow comes from the air.” The new study suggests that much of the microplastic found in Europe and the Arctic comes from the atmosphere and snow.
While there is growing concern about the effect of microplastics on the environment, scientists are still studying their possible harmful effects on humans and animals. “I hope the new study will lead to more research on this issue. I think microscopic plastic particles should be included in worldwide observations of air pollution levels.We really need to know what effects microplastics have on humans, especially if inhaled with the air that we breathe.” Bergmann said.
