1 . Most people have already heard we are facing an era of massive species extinction, that we run out of insect pollinators (传粉者) for our plantations and that springs are silent now. It is also agreed that a diverse nature is essential for our economic and emotional well-being and for human health. But how to achieve this?

Buildings produce dangerous emissions (排放物) polluting the air. The nation’s buildings are responsible for 40% of all US carbon emissions. Designing buildings that put the environment first is essential. Daniel Jaconetti, the National Sustainable Design Leader for the architecture firm HED tells Gb&d Magazine, “Our first responsibility is to educate and then to design for clients the best possible building that meets their needs.”

The best buildings are designed to be resilient (能复原的) , energy efficient, comfortable, and without poisonous chemicals. They are probably the ones-that make the most sense to people—being as efficient as possible. “You’re putting out fewer emissions.” Daniel Jaconetti tells Gb&d.

Eco-conscious design can be found-in a number of ways. The application of solar power is just one common design trend. Choosing eco-friendly building materials can also help. This can include a wide variety of materials, from bamboo to those recycled.

When looking for ways to cater to eco-friendly design, biophilia (热爱生物) has been used in architectural design to unite nature into the environment. With common elements of biophilic design in buildings including indoor trees and plants and living walls creatures, we can enjoy the various benefits associated with the presence of nature indoors. For already constructed homes, biophilic design element can help create an environmentally friendly atmosphere. Bringing in plants is just one major way to make an eco-friendly statement. Properly styling the greenery can be the difference between showcasing the tree itself and allowing it to complement the surrounding design.

2 . For Cruz, who grew up in Peru’s mountainous region of Cuzco, fog represents a massive opportunity. As a boy, he had to hike for more than an hour every day across hills to collect water from the nearest source. But over time, he realized that during the rainy season, droplets of water would gather in the large leaves of banana trees. So one day he and his father tried to build a canal system with the leaves to collect water and it turned out a success. But afterwards, he moved to Lima at the age of 25.

There, shocked by the water shortages and expensive water supply that some of the city’s poorest residents were faced with, Cruz set up El Movimiento Peruanos sin Agua in 2005. The idea was to deploy the method he learned in his hometown on a larger scale, which would provide free, independently sourced and easily accessible water to those who needed it most. He began installing (安装) a traditional fog catcher model developed in the 1980s.

At the highest point of Los Tres Miradores, there is a curious set of large structures that resemble a fleet of ships in the sky. They are so-called “fog catchers”. Netted devices, made of high density Raschel polyethylene and spanning several meters wide, are lined up at the top of a misty mound and linked by a network of tubes that lead to storage containers. The 40 fog catchers there provide enough water for 180 families, whether to bathe, clean, drink or to irrigate crops on small garden patches.

Supporters believe that fog catchers have the potential to improve water supply for communities around the world among the ever-challenging circumstances. German researcher Lummerich says, “They are cheap, easy to construct.” In a world searching for water supply systems, it is one important puzzle piece that can make an essential difference locally.

However, there are some issues. For one, fog catchers require space, which is not always easy to come by in cities, let alone urban slums. At the same time, fog catchers must be properly cleaned and maintained to stay effective. Most crucially, appropriate climate conditions are required. Fog isn’t everywhere.

9 . With needle-like teeth and sharp pointed nose, a gray nurse shark isn’t a creature that most people would want to meet. But Shalise Leesfield isn’t one of them.

The Australian teenager couldn’t think of a better creature to meet when scuba diving off the coast of South West Rocks, near her home in Port Macquarie, a coastal town north of Sydney.

“Many people say gray nurse sharks look frightening, but I think they are the sweetest animals ever,” she says.

The slow-moving sharks, which like to stay near the sea floor in warm, shallow waters, are — for the most part — harmless to humans. But the gray nurse shark is under threat. Populations have fallen and habitats have been lost due to ocean warming and human development, according to the International Union for Conservation of Nature (IUCN), which lists the species as seriously endangered.

One area where they can still be seen is Fish Rock, an underwater cavern (洞穴) with a unique ecosystem, 40 miles up the coast from Leesfield’s home. But fishers are allowed access within 200 meters of Fish Rock. This is leading to a drop in the number of gray nurse sharks and increased pollution, says Leesfield. She wants to enlarge the no-fishing area, establishing a protected zone.

With Leesfield’s efforts, the area has been nominated as a Hope Spot, which is part of the mission Blue program launched by famous oceanographer Sylvia Earle that identifies places as critically important to the ocean’s health and supports protection.

“When people think about Hope Spots, they think about Sydney Harbour or the Great Barrier Reef. So to get Fish Rock up on that list is just such incredible news,” she says.

Now, Leesfield is working with politician Cate Faehrmann, marine spokesperson for the Australian Greens party in New South Wales, to legalize protection of the sharks and make the no-fishing zone protected by the law.
