2 . When Purdue University researchers set out to develop a new paint, the goal was to create one that would reflect sunlight away from a building. It turns out they also set an official Guinness world record for the whitest paint on the planet.
“When we started this project about seven years ago, we had saving energy and fighting climate change in mind,” Professor Xiulin Ruan said.
The paint reflects 98.1% of solar radiation while also emitting infrared (红外线的) heat.
Because the paint absorbs less heat from the sun than it emits, a surface coated with this paint is cooled below the surrounding temperature without consuming power. Typical commercial white paint gets warmer rather than cooler, Paints on the market that are designed to reject heat reflect only 80%-90% of sunlight and can’t make surfaces cooler than their surroundings.
“Conventional air conditioners consume power that is often from burning fossil fuel. Meanwhile, while they move the heat from inside of a house to the outside, they turn the electricity into heat and leave even more heat to the surrounding and earth, further causing a heat island effect and warming up the Earth,” Professor Ruan told IFLScience.
“In contrast, our paint does not consume any power, and directly sends off all the heat to the deep space, thus helping cooling down the Earth. According to a previous model, painting 0.5-1% of the Earth’s surface (roofs, roads, cars, unused land, etc) with our paint will stop the warming trend. Painting many human made-structures would be a great way to fight the climate crisis in many ways. The paint is not yet available commercially and the scientists are working with a commercial company to speed up the paint production and put it on the market.

3 . Be a Green Guest
When people take a vacation, they often take vacation from responsibility, too. Our behavior at hotels is one of the biggest problems. We have our linens(纺织品) washed daily for us, and are provided with an endless stream of hot water — what’s not to love about that? But all of this luxury equals serious consequences for the environment. More and more hotels are becoming eco-friendly. They offer programs and facilities that save water and energy. That’s a good start,
•Just say “no” to hotel shampoos
In America alone, there are about 50,000 hotels. Hotel management normally leaves out two small bottles for each hotel room every day.
•Turn off the lights.
•
Sure, it’s a luxury to have sheets and towels cleaned every day, but that’s all it is. Washing a set of bed sheets and a pair of bathroom towels requires about 12-16 gallons of water. See if there is a policy for requesting that your towels and linens get washed weekly.
| A．You do it when you’re at home, right? |
| B．Don’t shower too many times in hotels. |
| C．Don’t have your linens washed every day. |
| D．but they can do more to reduce these energy waste. |
| E．The little plastic bottles may not even get recycled. |
| F．but there is a lot more you can do to cut down the amount. |
| G．In some hotels, it’s as simple as hanging towels back up on a hook. |
4 . Wild beavers (河狸) are back! Experts say that the wild beaver families are doing well. The beavers are even boosting wildlife and the environment!
Over ten years ago, a family of beavers turned up in a part of the river Otter, in Devon. No one knew exactly where they came from. It was a big surprise wild beavers hadn’t lived in England for around 400 years!
In 2015, the government allowed the beavers to stay there as part of a test. They wanted to see if these animals could be reintroduced to the wild. The test ends in February. Some scientists from the University of Exeter already say the beavers help the wildlife in the area. One scientist called it “an amazing story”.
A lot of this is because of dams (水坝). Beavers build dams along the river. This creates deep pools in the riverbed and slows the water down. Scientists say this is perfect for many different types of plants and animals! Many plants are growing near the beavers. Different types of animals are also becoming more and more in the river. Beavers also help make flooding less, scientists say. The beavers’ dams slow down the speed of the river, especially after heavy rain.
Beavers aren’t the only animals that are being reintroduced to the wild! In 2019, red squirrels were brought back to an area of the Scottish Highlands. Further away, the world's rarest (罕见的) duck, the Madagascar pochard, is making a comeback. It was set free into the wild on the African island in 2019 and is doing well.
Who knows what other animals might be making a comeback?

5 . An earthquake is one of the most common natural disasters. It may cause great damage. So it is wise to learn some simple safety tips to protect yourself or your family members.
Fragile items like those made of glass are easily broken and should usually be placed on a lower surface, near the ground instead of placing them in the cupboards higher up. Never place them near your bed, sofas and other furniture where you would be sitting or lying down. So when there is a strong movement, these pieces will fall on the floor directly, not on you.
There is a strong chance of short circuits and fire during an earthquake. Make sure you turn off electrical connections and gas immediately when an earthquake happens.
During an earthquake, lie beneath an object that is not easily damaged. Do not go near objects that could directly fall on you. Never use the elevator to go down. Stay inside until the shaking stops and it is safe to go outside. Research has shown that most injuries happen when people inside buildings try to go out. Use the staircases (楼梯) at all times.
If you are outdoors, do not take shelter under a tree, streetlights, electric poles or tall buildings. If you are driving, stop your car and stay in a safe place. Do not park your car under a tree or any tall object.
If trapped in ruins, cover your mouth with a handkerchief or clothing. Tap on a pipe or the wall so rescuers can find you. Use a whistle (哨子) if one is available. Never shout for help. Shouting can cause you to breathe in dangerous amounts of dust. Do not light a match because you may burn yourself.

6 . All living things on Earth need water to live. Yet humans are facing serious water problems. According to the United Nations, today over 663 million people live without a safe water supply close to home.
To remind people of the importance of water, the UN first set up World Water Day in 1993. It is on Mar 22 each year. From Mar 22 to 28 is also the China Water Week. The first year’s theme is “Waste water”. It tried to call people to reuse waste water instead of wasting it.
In Australia people make good use of waste water. Most Australians have a grass lawn around their home instead of washing the car in the street. Many of them wash it on the lawn to keep the grass longer so that it covers the ground and reduce evaporation.
Rainwater may seem useless to you. But you can also reuse it. People in Germany collect rainwater to wash their toilets. Most houses in the country that are built in the last few years have rainwater collection devices (设备). Rainwater is collected from the root, and then linked to the toilet. But if you don’t have the device just put a bucket (桶) under your roof when it rains.
Water makes up 71 percent of Earth’s surface. But we can only use a very small part of it. Only about 3 percent of the world’s water is fresh water. It’s in lakes, rivers and underground.
Over 80 percent of the w
aste water in the world goes back into the nature. It has not been cleaned and pollutes the rivers and lakes. Unsafe water makes around 842,000 people die each year.
By 2030, about half of the world’s population could be facing water problem. By 2050, as many as seven billion people across the world could not have enough water supplies. The world’s population might be 9.3 billion by then.

7 . A nighttime building fire in southern Taiwan Province that took hours to bring under control killed 46 people on Thursday. Officials in the city of Kaohsiung said at least 41 people were injured.
The fire started early Thursday morning local time. A statement by the fire department described it as “extremely fierce.” Flames and smoke poured from the lower floors as firefighters tried to control the fire.
The number of dead rose during the day as rescue workers searched the building which combined businesses and homes. By late afternoon, officials confirmed 32 people had died, while 14 people, who showed no signs of life, were among 55 taken to the hospital. In Taiwan, official confirmation of a death is made at the hospital.
Firefighters could be seen spraying water into the middle floors of the 13-floor building. One woman, who was not identified, said on Taiwanese television that her 60-to-70-year-old parents were still inside as rescue efforts continued. Taiwan’s Central News Agency reported that officials said the building’s age and waste blocking many areas made search and rescue efforts more difficult.
Many of the people living in the 40-year-old building were retired and lived alone in apartments as small as 13 square meters, local media reported. The building had 120 living spaces on the upper floors. It also had a closed movie theater, disused restaurants and karaoke businesses below them, the Central News Agency said. Mayor Chen Chi-mai said the building was partly abandoned.
The United Daily News, a major newspaper, said fire extinguishers(灭火器) had been put in place last month. But there were only three on each floor because the residents could not pay for more.
The fire appeared to have started on the ground floor. Investigators were examining a first-floor tea shop whose owner reportedly fought with his girlfriend the day before. They had not ruled out that the fire may have been set on purpose, The United Daily News reported.

8 . More than one billion pounds of pumpkins are grown in the U.S. every year, and after they’ve been used for Halloween, millions of them will end up in a waste yard.
“Driving around after Halloween, you see so many pumpkins on top of their garbage cans. All of them will go to a waste yard and become methane gas(沼气),” says Kay McKeen, director of an environmental education organization based in Illinois.
Methane is a greenhouse gas. Compared to CO2, it warms the atmosphere in a shorter amount of time, which means it’s a most important cause of climate change. And waste yards—where we send as much as 40 percent of the food we produce—take up 14 percent of methane produced in the US every year.
That’s why, in 2014, McKeen began a collection event where local people can bring their waste pumpkins to 69 different locations to send them off to the bins, and—of course—smash them to pieces.
“It puts nutrients(营养) back in our soil, it saves water, it doesn’t make methane gas—it’s just a win-win,” says McKeen.
But not everyone has access to pumpkin smashing events, so we asked our newsletter readers how they reduce their pumpkin waste. The answers are various, ranging from baking sweet treats to bringing a pumpkin treat to farm animals.
