1 . The company SpaceX has already launched hundreds of its Star-link satellites, with plans to put as many as 42,000 of them in Earth orbit. Its goal is to provide high-speed Internet to billions of people. Moving toward that kind of access is important, but it comes at a cost. Glittering with reflected sunlight, these first orbiters, sent up in the past year, are brighter than 99 percent of the 5,000 or so other satellites now circling Earth, and obviously there are going to be a lot more. This sudden increase is bad for astronomy: the probability of a Star-link satellite crossing a telescope’s field of view and ruining an observation will be quite high near sunset. For that reason, my fellow astronomers have signed a petition (请愿书) calling for governments to protect the night sky from this invasion.
In response to protests, SpaceX has promised to address the visibility problem by, for example, applying experimental coatings — essentially painting the satellites black — but the company’s aggressive launch schedule remains unchanged. And the satellites’ illuminated (被照亮) surfaces are mostly their solar panels — exactly the part that cannot be painted over.
Unfortunately, at present no regulations govern how bright a single satellite can be, let alone thousands of them together. Even if there were such regulations, one nation’s laws can not hinder (阻碍) another country’s launches. Space literally has no borders, and the sky will need to be protected at an international level. As a consequence, we hope that the United Nations will find a way to think outside of the box to save the sky for everyone.
When I was growing up in Montana, it was a game to be the first to find a moving satellite among the host of stars in the night sky. Soon it could be a game to recognize the constellations (星座) behind a swarm of moving points of light.

2 . 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.

3 . Light pollution is blocking a starry view of the night sky for more than half of people across England, a research has found.
Fifty-seven percent of stargazers(观星者)struggled to see more than 10 stars, while just 2% of participants said they experienced a truly dark sky enabling them to count more than 30, according to the research by the Campaign to Protect Rural England(CPRE). People in the countryside were encouraged to count how many stars they could see with eyes within the constellation(星座)of Orion, which is visible only in the winter months.
Campaigners said the results of the star count, supported by the British Astronomical Association, showed the problem of light pollution and how it affected one of the countryside's most magical sights-a dark, starry night sky. They said the results of the research to map England's night skies suggested more could be done by the government, local councils and the general public to lessen the negative effects of artificial light from streets and buildings.
Emma Marrington, dark skies campaigner at the CPRE, said, “We're hugely grateful to the people who took the time to get out and take part in our star count. But it's deeply disappointing that the vast majority were unable to experience the natural wonder of a truly dark sky blanketed with stars. Without intervention, our night sky will continue to be lost under a covering of artificial light, ruining the health of the natural world.”
She added, “The star count results show just how far-reaching the light from street lights and buildings can be seen. Light doesn't respect boundaries, and careless use can see it spread for miles from cities.”
She suggested better-designed lighting, street light dimming(暗淡)systems and partnight lighting where some street lights are turned off during the small hours should provide an opportunity to limit the damage caused by light pollution, reduce carbon emissions and save money.
