Deserts could be the best places on Earth for harvesting solar power. They are spacious, relatively flat, and never short of sunlight. So researchers imagine it might be possible to transform the world’s largest desert, the Sahara, into a large solar farm, capable of meeting four times the world’s current energy demand.
While the black surfaces of solar panels absorb most of the sunlight that reaches them, only around 15% of that incoming energy gets turned into electricity. The rest is returned to the environment as heat, affecting the climate. If these effects were only local, they might not matter in a thinly populated desert. But the area of the installations in the Sahara would be vast, covering thousands of square miles. Heat released from an area this size will be redistributed by the flow of air in the atmosphere, having regional and even global effects on the climate.
A 2018 study used a climate model to assess the effects of building massive solar farms in the Sahara. The model revealed that when the size of the solar farm reaches 20% of the total area of the Sahara, the heat released by the darker solar panels creates a big temperature difference between the land and the surrounding oceans that ultimately lowers surface air pressure and causes wet air to rise and condense (凝结) into raindrops. With more rainfall, plants grow and the desert reflects less of the sun’s energy since vegetation absorbs light better than sand and soil. With more plants present, more water is evaporated (蒸发), creating a better environment that causes vegetation to spread.
So, a large solar farm could generate enough energy and at the same time turn one of the most abominable environments on Earth into a habitable place. Sounds perfect, right? Not quite. In a recent study, we used an advanced Earth system model to closely examine how Saharan solar farms interact with the climate. It showed there could be unintended effects in remote parts of the land and ocean.
We are only beginning to understand the potential consequences of establishing massive solar farms in deserts. Solutions like this may help society reduce the use of fossil energy, but Earth system studies like ours underscore the importance of considering the numerous coupled responses of the atmosphere, oceans, and land surface when examining their benefits and risks.

4 . When most kids go to the beach, they’re too focused on making sandcastles and splashing around to notice litter, but several years ago, for 7-year-old Cash Daniels, noticing a plastic straw sparked a lifelong passion for saving the planet.
Cash, who is now known as the “conservation kid”, has always loved nature. He grew up fishing along the Chattanooga River, after all! But once he learned that 80 percent of all trash from land and rivers ends up in the ocean, he couldn’t sit back.
He started with cleanups along the river, something that quickly went from a family affair to a community effort with volunteers and neighbors. In 2019, Cash, together with a Canadian conservationist, Ella Galaski-Rossen, started a nonprofit called the Cleanup Kids. Despite living in different countries, they managed to create educational videos on their YouTube channel. “We hope to be a really big nonprofit that eliminates plastic in the U. S. and Canada,” Cash said. “We want to inform kids and adults in the landlocked states on how their actions are connected to the water and the ocean,” Cash said.
Cash was selected as one of America’s top 10 youth volunteers of 2021 by the Prudential Spirit of Community Awards. He also earned the title of National Honoree, where he received a$5,000 grant to go to a nonprofit of his choice, and he became the first person to win the Youth Conservationist Award two years in a row from the Tennessee Wildlife Federation.
“I want to travel the world, teach others, and help them feel connected to the ocean. Because if you are connected to the ocean-if you love it and what lives in it—you’ll want to protect it,” he said. “This is my fun, and it becomes more fun with every new discovery.”

5 . How to Survive a Lightning Strike?
According to the National Weather Service, almost two-thirds of lightning accidents occur as people enjoy leisure activities outdoors.
Keep an eye on the sky
Before you head out for hiking, check maps to locate visitor centers, campground buildings, or rest areas along your route. Once you hear thunder, see lightning, or sense that a storm is approaching, don’t hesistate to use your plan. Hikers are strongly advised to watch continually for the nearest shelter.
Know the storm’s distance
Count the seconds between the flash and the following sound of thunder. Divide the number of seconds by five to calculate the number of miles between you and the storm. For example, if the number of seconds is 30, then the distance inbetween equals six miles, and find shelter immediately.
A.Make a safety plan |
B.Check the weather forecast ahead |
C.If this simple math is still confusing |
D.If you get indoors as soon as possible |
E.People are struck while camping, hiking or boating |
F.Staying calm will help you avoid meeting further dangers |
G.Car campers can stay in the vehicles when no other shelter is available |
6 . Don’t call Madison Stewart an environmentalist. She sees herself simply as an individual taking action in defense of something she loves that’s in need of protection.
Despite her youth, the 24-year-old is an undersea veteran (老手). She grew up sailing around the Great Barrier Reef on her parents’ boat and spent her early life free diving while patiently waiting for the day when she could get her scuba diving (水肺潜水) certification, aged 12. Already impressed by sharks, Madison was now pleased to be able to observe them in their own world. “I got to know the sharks...I could recognize them by sight,” Madison says. “Other people had dogs around them growing up. I had sharks.”
But within a couple of years, she saw a great reduction in shark numbers on the reef. “One day I went in the water and couldn’t find my sharks anywhere, sharks I’d spent my childhood with,” she says. “They’d been caught and killed.” It was a great moment for Madison.
She left school at 14 to be homeschooled so she could spend more time in the ocean. She taught herself to shoot underwater video to document sharks in their own world and share her sense of wonder with others. She launched a YouTube channel and built a huge following for her documentaries where she focuses on issues like inadequate protection for some shark species and the global shark fin (鳍) industry.
In 2014 Madison was the subject of the encouraging documentary Shark Girl, which introduced her to a global audience. In 2017 she appeared as an “Ocean Guardian” in the documentary Blue that explored a lot of threats to the world’s marine environments, including the damaging effect of the global shark fishery. The film encourages viewers to get involved and includes practical steps to guide them to do so. It shows Madison’s philosophy that the power of the individual to make a difference by their own direct action should never be underestimated.

8 . According to the Solar Energy Industry Association, the number of solar panels installed(安装)has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them.
Solar developers want to put up panels as quickly and cheaply as possible, so they haven’t given much thought to what they put under them. Often, they’ll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil.
“Solar projects need to be good neighbors,” says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE)project. “They need to be protectors of the land and contribute to the agricultural economy.” InSPIRE is investigating practical approaches to “low-impact” solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫).
Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms.
Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. “These pollinator-friendly solar farms can have a valuable impact on everything that’s going on in the landscape,” says Macknick.

10 . Fashion designers are always looking for new materials to work with. Lately, it’s all about environment-friendly materials -- recycled tires, mushrooms, even pineapple fibers! What if you want such a pair of shoes? Thaely is here to help.
This sneaker brand out of Dubai wants to fight the growing problem of plastic pollution. Led by 23-year-old Indian businessman Ashay Bhave, they may have found a winning approach: making shoes out of plastic grocery bags. “Thaely” means “plastic bag” in the Hindi language.
“I was looking to create footwear that is cost-effective and safe for the environment,” Bhave said in an interview with a newspaper. “I needed to come up with something that uses recycled plastic without creating any more plastic waste. ”Plastic bags were the perfect solution. He said five trillion plastic bags are used around the world each year. “I was motivated to find a solution to this problem,” Bhave said.
That solution was the fiber called ThaelyTex. Made entirely from plastic bags, the material looks and feels like leather. That sounds promising. Better yet, the production process requires no additional chemicals and produces no poisonous by-products. The result is a smart-looking pair of white low-top sneakers.
Bhave wouldn’t expose the full process for making ThaelyTex, but he said that each pair of shoes was made from up to 15 plastic bags and 22 plastic bottles. Where do they get the materials? Bhave told Elle that was the hardest part. “The biggest challenge we faced was right at the first step of acquiring the plastic bags. ”
Finally, they got help from TrioTap Technologies, a waste management plant. Bhave said they offered to collect the bags and also process them into ThaelyTex.
So far, it seems like things are falling into place. There are already hundreds of pre-orders in place. It sounds like they have some plans for the future. “We have a few more colors coming up,” said Bhave. They also plan to put out a high-top model and bring in a line of clothing. Let’s hope their growth is also friendly to the environment.
1. Why did Bhave choose to make shoes out of plastic bags?A.To set a new footwear trend. |
B.To test new materials for footwear. |
C.To reduce the use of plastic bags in his home country. |
D.To use recycled plastic in an environment-friendly way. |
A.Having a few more colors for Thaely. | B.Processing plastic bags into ThaelyTex. |
C.Collecting enough production materials | D.Dealing with many poisonous by-products |
A.produce | B.conserve |
C.provide | D.broadcast |
A.Bhave: a promising young man |
B.Thaely: killer of waste plastic bags |
C.ThaelyTex: material out of plastic bags |
D.TrioTap Technologies: a waste management plant |
