Nature has inspired many fascinating designs architecture. Singapore's Art Science Museum， (shape) to resemble a lotus flower，was designed to show the connection between nature and the modern city environment. Visitors are often amazed to find (they) in an urban building that so truly captures the beauty of natural forms. Zimbabwean architect Mick Pearce (inspire) to create Harare's Eastgate Centre while (watch) termites constructing their nests. The design reduces the need for (tradition) air conditioning and heating systems，so the building uses less energy and costs less to run. The (world) first algaepowered building is in Hamburg，Germany. Its surface is covered in panels contain algae. The building therefore not only uses less energy， also reduces damage to the environment by generating its own renewable energy. Creating such (building) enables us to live in closer harmony with our environment.

Modeste Traore has lived his whole life near Lake Wegnia, in the Sahel area of Mali. The lake's fish have provided him with a way to earn money to support his extended family. However, because he can't catch enough fish to feed his family, he now raises farm animals. But as temperatures rise, evaporation increases, making the body of water shrinks. Studies have linked rising temperatures on Earth's surface to climate change.

The lake is shrinking, so are the chances of his children becoming fishermen. “If things go on like this, I don't think our children can become fishermen like us. They will have to choose other jobs，” the 56-­year-­old Traore said. “During the rainy season, there is a lot of water but as soon as it's over, there is no water left in the lake. We are fishermen. I don't think our children will be，” he said.

Lake Wegnia is in the Sahel region of Koulikoro, around 120 kilometers north of Mali's capital, Bamako. Some 12,000 people, including fishermen and farmers, depend on it for food, water and employment. But the lake has shrunk by 20 percent since 2017.

The UN expects temperatures there to increase 1.5 times higher than the average increase worldwide. UN officials note that the flooding and a severe lack of rainfall can cause problems in the Sahel: Food insecurity, the fight over farmland and the fast population growth can lead to conflict.

Aid group is leading the Eco­Lac Wegnia project. The group is working to improve water management and fight the effects of global warming. Moussa Savagodo is Eco­Lac Wegnia's local representative. He says that failing to make changes quickly can mean the lake will disappear completely in less than 5 years.

People in the rural areas Wegnia and KononiSirakoro have planted 56,000 trees in the past two years. And they are better controlling their water by building stone barriers to help the soil keep the rain that does fall. The progress and international official support are not enough for them, however. More and more people are turning to other agriculture.

In the middle of the 19th century, a fever dream of riches beyond measure drew countless explorers west to the mountains of central California. Although the gold rush ended up being a bust_for many who sought a fortune, some of those explorers discovered a natural treasure that would draw permanent settlers to Yosemite Valley in the following decade.

Vast wilderness, beautiful mountains, countless waterfalls, and abundant wildlife drew Native Americans to Yosemite roughly 10, 000 years ago. The first non­native tourists arrived in the mid­1850s after reports from gold seekers told of an area of breathtaking beauty that no words were able to describe.

Fortunately, some of Yosemite's earliest settlers recognized that Yosemite's natural beauty and resources needed to be preserved for future generations. In the midst of the Civil War, President Abraham Lincoln signed a grant to protect Yosemite permanently, thus making it the nation's first land to be dedicated to recreation and setting the stage for what would become the national park system.

One of Yosemite's earliest ambassadors was Scottish­American naturalist and writer John Muir. After living in Yosemite for a few years, he helped define its proposed boundaries. He also wrote articles that helped lead to its official title as a National Park in 1890. He later co­founded the Sierra Club in 1892 to advocate for its continued preservation and protection.

Located on the western slope of the Sierra Nevada mountain range in central California, Yosemite National Park runs across nearly 748, 000 acres, almost 95%of which is wilderness. Around four million visitors come to Yosemite each year to camp, hike its miles of trails, climb its rock formations, and photograph its impressive sights. Are you ready to visit Yosemite National Park? Which of Yosemite's sights would you most like to experience?

Quite simply, school trips are the journeys which take place outside a student's normal environment. Educational trips are normally done in a museum or a historic place. They could provide a better understanding as the students would be able to make a connection between a place, time, or even people in history and something they've seen on a field trip.

A trip to the zoo could provide a better understanding of animals. Biology is even better when there are proper animals to be named. Teachers and headmasters are advised to give the students prizes and rewards for different accomplishments done on a field trip.

Planetariums(天文馆) could help students remember constellations (星座) better. Planetariums could help them see that the earth is just a small planet in the universe and that there is no reason not to explore. If you are a teacher and you 're lucky, you may have taken the next greatest astronaut to the planetarium on a school trip.

Also they could help them see that there are so many living things that depend on them and how they can take care of nature. Children are very easily inspired. Therefore, it is necessary for teachers to often take their students to field trips, where they can have fun learning.
