Imagine how you’d feel if you had to get more than 9,000 tons of junk out to the sidewalk. That’s how much trash is floating around in space. In fact, there’s about 4 million pounds flying over our heads in low-Earth orbit. Daan, a Dutch artist, and his team at Space Waste Lab have come up with a creative plan that could clear up space junk in a spectacular fashion.
①Most space waste comes from dead satellites and rockets. Functioning satellites are the backbone of the information systems that keep our world running smoothly. But all the satellites eventually become obsolete within just a few decades. When they die out, there’s the problem of them drifting in outer space, collecting in what scientists call the “graveyard orbit.”
Maybe you’re thinking, “Why should I care about garbage 12,500 miles above me?” Well, all that fun stuff that satellites help beam down to us—mobile games, Instagram, cat videos—could be shut down by space waste. Lots of old junk floating around up there, plus new satellites added each year, means more and more high-speed collisions (碰撞). And when chunks of junk crash into one another, they break apart into millions of pieces, quickly building up speed and turning into fast-moving objects, which are dangerous to operational satellites as well as astronauts working on the International Space Station.
②Space waste is a problem that’s escalated so much, some scientists say that by 2050 we’ll be forced to stop launching new spacecraft altogether, including new satellites. Think about that for a minute. When the last satellites finally become disused, GPS, cell phones, and the Internet will no longer function.
③So we have to find a way to deal with this space garbage, and Daan pictures a sort of trash pickup, which involves groups of small spacecraft casting large nets into orbit that would collect space debris (碎片) and send it back toward Earth at top speed. Here’s the best part—while reentering Earth’s atmosphere, the pieces of junk would burn up all at once, creating a light show similar to hundreds of shooting stars falling in the night sky. A spectacle indeed!
To get ready for such an amazing effort, Space Waste Lab has been traveling to major cities across Europe and enlightening the public on the problem of the junk in space. ④But Daan doesn’t just talk about ways to relieve the problem—he’s created something a little grander than that. In October 2018, his team launched Space Waste Lab Performance, an outdoor art exhibition that shows the location of each piece of space trash using large lasers that make each debris look a bit like a star wandering slowly and silently over the sky, allowing viewers to wave and say, “Hallo, space trash!”

Leftover again? Hurray
Here’s the deal: You’re as hungry as a horse and you want a delicious meal from a fine restaurant, but you’re a little low on funds.
So what do you do? If you happen to live in Europe, the answer is as easy as pie: You pull out your smartphone or tablet, and tap Too Good To Go, Europe’s most popular app. Approximately 23,000 restaurants and food sellers post their leftover offerings on the app for half their usual cost.
Why all this incredible generosity? Unbelievably, one-third of the world’s food is thrown away, and nearly one billion people don’t have enough to eat. Besides, burning wasted food releases harmful carbon dioxide emissions into the atmosphere, which contributes to climate change. That’s why environment-minded companies around the world are creating apps for phones, tablets, and other smart devices that connect uneaten food with people who want or need it.
After a long day at work, Anne, a 34-year-old student, pulls out her smartphone and chooses a noodle dish—pasta with mushrooms. Then she heads to a restaurant on the banks of the Spree River, where the owner packs her dinner and also offers her a scoop of free ice cream, which is a reward for bringing her own container.
Indeed, there are many programs serving the same mission around the world. In America, people are using an app called Food for All. One hour before a restaurant closes, its staff can post leftover meals to the app for up to 80 percent off menu prices. The app also allows customers to donate leftover meals to others.
In the Netherlands, 77,000 people have downloaded an app called NoFoodWasted. This program allows grocery store workers to share products that are approaching their expiration dates with customers who might need them.
Some countries are taking their commitment to reducing food waste a step further. France and the Czech Republic, for example, have laws that prohibit restaurants and grocery stores from throwing away food. Instead, workers are required to donate that food to charity.
So think about if there might be a better use for your uneaten vegetables. The planet will thank you.

Surprise! A New Penguin
A team of scientists in New Zealand recently came across the remains of a previously unknown species of penguin—by mistake. The discovery of the Waitaha penguin species, which has been extinct for 500 years, is exciting news for the scientific community 1. it gives new insight into how past extinction events can help shape the present environment.
The researchers uncovered the Waitaha penguin remains while studying New Zealand’s rare yellow-eyed penguin. The team wanted to investigate the effects 2. humans have had on the now endangered species. They studied centuries-old bones from 3. they thought were yellow-eyed penguins and compared them with the bones of modern yellow-eyed penguins. Surprisingly, some of the bones were older than 4. (expect). Even more shockingly, the DNA in the bones indicated that they did not belong to yellow-eyed penguins. The scientists concluded that these very old bones 5. have belonged to a previously unknown species, which they named the Waitaha penguin.
By studying the bones, scientists further concluded that the Waitaha penguin was once native 6. New Zealand. But after the settlement of humans on the island country, its population 7. (wipe) out.
Based on the ages of the bones of both penguin species, the team discovered a gap in time between the disappearance of the Waitaha and the arrival of the yellow-eyed penguin. The time gap indicates that the extinction of the Waitaha penguin created the opportunity for the yellow-eyed penguin population 8. (migrate) to New Zealand.
9. yellow-eyed penguins thrived （兴盛） in New Zealand for many years, that species now also faces extinction. The yellow-eyed penguin today is considered one of the world’s 10. (rare) species of penguin, with an estimated population of 7,000 that is now the focus of an extensive conservation effort in New Zealand.
