1 . Diving in the ocean, marine biologist Erika Woolsey has seen how coral reefs (珊瑚礁) are being damaged by climate change. It has made her decide to find a way to share her experience —including those who can’t easily explore the ocean.
Through her non-profit, The Hydrous, Woolsey is using virtual reality to bring the ocean to everyone. Scientists, filmmakers and divers are taking people on immersive (沉浸式的) virtual dives, attracting attention to reef damage and expecting action to protect our sea. About 25% of marine species depend on coral reefs. However, climate change, pollution and overfishing have done harm to around half the world’s shallow water coral reefs.
Twenty years of underwater exploration has given Woolsey a detailed understanding of the dangerous situations facing reefs. “I’ve seen this first-hand shift. Healthy colourful coral reefs become what look like the moonscape step by step,” Woolsey says.
It is through this experience that The Hydrous team set out to recreate with their award-winning film Immerse. Intended to watch with a VR headset, viewers join Woolsey for a nine-minute guided virtual dive on the coral reefs, immersed in a 360-degree underwater view.
They swim alongside sea turtles and sharks before witnessing the worsening of the reefs. The experience often brings out strong feelings. “As soon as people take off that headset and look me in the eye, they want to tell me a story about their ocean experience,” Woolsey says. “It’s that human connection to our ocean that will solve our ocean problems.”
Woolsey hopes advances in camera technology will allow her team to take more and more people to places in the ocean that are under-explored and places further away from human civilization. They are developing a virtual experience that will put the people in the role of a marine biologist, carrying out biodiversity surveys underwater, and even transporting the viewers to space to monitor global sea surface temperatures.

2 . Few sights fill you with nostalgia (怀旧) like the fireflies dancing at night.
Create a firefly habitat
Flashing lights are an important part in fireflies life. As the sun sets, male fireflies move around while flashing their lights to signal their interest. If a nearby female is interested, she flashes back from her position to the ground, and the males fly down to find her. “All of that has to happen for the next generation to survive,” says Lewis. “However, light pollution makes those scenes much harder to see. It’s like cutting a phone line. It really stops the romance.

3 . This past July was the hottest recorded month in human history. Heat waves brake temperature records worldwide. It’s more than just a matter of sweaty discomfort. As climate change worsens, access to artificially cooled spaces is rapidly becoming a health necessity.
Yet standard air-conditioning systems leave us trapped in a negative feedback cycle: the hotter it is, the more people use the air condition er and the more energy is consumed as a result. Cooling is the fastest-growing single source of energy use in buildings, according to the International Energy Agency. Breaking the cycle requires new innovations that will help bring cooler air to more people with less environmental impact.
Standard air-conditioning systems cool and dehumidify (除湿) through a relatively inefficient mechanism: in order to condense (冷凝) water out of the air, they overcool that air past the point of comfort. Many new designs therefore separate the dehumidification and cooling processes, which avoids the need to overcool. For example, some new air conditioner designs pull water from the air with desiccant (干燥剂) materials. The dried air can then be cooled to a more reasonable temperature. Massachusetts-based start-up Transaera claims that the system it is developing could use 35 percent less energy than the average standard air-conditioning unit.
However, the gains in efficiency might not help us get rid of the impact of air-conditioning. “It won’t work to simply replace every existing air conditioner with a better model and call it a day,” says Nicole Miranda, an engineer at the University of Oxford. “Instead, a truly coder future will have to employ other strategies. It’s critical to bring greenery and water bodies into cities to take advantage of natural airflow.”
“Cooling is a challenge involving many aspects,” says Sneha Sachar, an expert at the nonprofit organization ClimateWorks. “There isn’t one strategy or one answer. We need a combination of better buildings and cities, better technologies and a better understanding that the true cost of air-conditioning extends beyond electric bills.”

4 . In the office of remote sensing scientist Liu Shaochuang, there is a huge photograph of a camel he snapped a decade ago in Xinjiang. He crouched for hours by a pool of water in the Gobi Desert to capture the image.
Since 2012, he has led a team in tracking and studying wild camels using satellite remote sensing technology.
Unlike zoologists who focus on species, Liu has studied the interrelationship between endangered animals and their environment, which he believes will help develop better protection strategies in the face of climate change.
His interest in wild camels began when his team tested a prototype(雏形)design of the lunar rover Yutu in the desert. Living in the harsh deserts in northwestern China and southwestern Mongolia, camels are listed as critically endangered animals. Experts estimate that the population of this species is currently less than 1, 000, of which around 650 are in China.
“Ten years ago, the research relied solely on human observation, which was very primitive, ”Liu says. Because camels are fully migratory and can travel over long distances, scientists used to learn their habits by studying hoof prints and droppings. It was hard to find one camel in the desert, let alone track it. But Liu thought his expertise in satellite navigation(导航)and remote sensing might come in useful in the study of wild camels.
It was not easy at first. Liu learned zoology from scratch. His team had to spend several weeks each year braving dust and sandstorms in the vastness of the Gobi Desert seeking out camels. A scar on his right eyebrow is the result of a rollover accident on a rugged mountain road in Xinjiang.
“The most exciting moment was attaching a satellite positioning collar to a wild camel. ”The tracking collar, equipped with special receivers, weighs only a few hundred grams. It can detach automatically and will not have a negative impact on the daily lives of the animals. The locations of the tracked animals are transmitted via satellite every day. Based on the data, scientists can get to know their migratory paths, living environments and possible threats they may meet with.
For Liu, it is worth the significant sci-tech effort to study such a rare species. He adds wildlife protection and research will become more precise and efficient with the help of technology.

6 . When he was 22, Rob Stewart traveled the world for four years. He wanted to call attention to the mistreatment of sharks. His 2007 film, Sharkwater, documents the cruel practice of removing sharks’ fins (鳍) for money and leaving the animals to die. In his latest documentary, Revolution, Stewart takes on an even bigger challenge: climate change.
The Canadian filmmaker says that climate change has harmed people and places everywhere: “It is stronger than any government or organization. If we educate people, they will make better decisions about protecting natural resources.”
According to a recent report on climate change, “The atmosphere and ocean have warmed, the amounts of snow and ice have reduced, and sea levels have risen.” These developments are endangering crops, wildlife, fish, and even people.
Stewart says that the consequences of climate change will be irreversible unless people take action, especially young people. “It’s up to kids to be the moral compass (道德指南) of society,” he believes, “and say, ‘Guys, this is not right.’”
Many kids took action after seeing Sharkwater. Elementary school students in the Northern Mariana Islands, for example, got their local government to ban the sale of shark fins.
Felix Finkbeiner, 17, of Germany, is also part of the “revolution” to save the planet. In 2007, Felix started a youth group called Plant-for-the-Planet, whose motto is “Stop Talking. Start Planting.” The group raises money to plant trees. So far, Plant-for-the-Planet has planted nearly 200 trees around the world. “Future generations are the ones who will be suffering the most from inaction (无作为),” Felix says. His goal is to plant millions of additional trees.
“When we started four years ago,” Felix tells Stewart in Revolution, “we thought we had to save the polar bear. We thought we had to save the environment. But soon after, we found out that it’s about our future, that we have to save our own future.”

7 . A company in San Francisco, California, has found a way to turn used plastic bottles into women's shoes.
Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.
A San Francisco start-up company called Rothy's, however, turns this plastic waste into environmentally friendly shoes. Roth Martin is the company's co-founder. He explains how they turn plastic into soft material for women's feet. They take the plastic, clean it, and break it down into small pieces. Then they press them through a device that makes soft fibers. Those fibers are then combined together. This is done by a 3D machine. It is designed to reduce waste while making the shoes. The knitted stuff and the inner part of the shoe are then attached to the shoe's outer part, called the sole. This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.
Rothy's shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $ 125 or $ 145 per pair, depending on the design. After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew. Martin says there is no shortage of material to fill that demand. “We're not going to run out of water bottles any time soon. So we have a limitless supply of material, and I think that is a good sign for our future.” When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled material to make other products.
For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.
