5 . A city is rising from the waters of the Indian Ocean. In a lagoon (泄湖),just 10 minutes by boat from Malé, the Maldivian capital, a floating (漂浮) city, big enough to house 20,000 people, is being constructed (建造)。

Designed in a pattern (模式) similar to brain coral (脑珊瑚),the city will consist of 5.000 floating units including houses, restaurants, shops and schools, with rivers running in between. Residents start to move in by early 2024, and the whole city is due to be completed by 2027. The project is not meant as a wild experiment: it’s being built as a practical solution to the reality of sea level rise.

Containing 1.190 low-lying islands, the Maldives is one of the world’s weakest nations to climate change. Eighty percent of its land area is less than one metre above sea level, and with sea level projected to rise up to a metre by the end of the century, almost the entire country would go under the water.

The units are constructed in a local shipyard, then pulled to the floating city. Once in position, they are joined to a large underwater concrete frame which is fixed to the seabed on telescopic (可伸缩的) steel poles that let it gently flow with the waves.

Koen Olthuis, founder of Waterstudio, the company that designed the city, said that the possible environmental effect of the structure was assessed by local coral experts and permitted by government authorities before construction began. The aim is for the city to be self-sufficient and have all the functions as one on land. There will be electricity powered mainly by solar energy. As an alternative to air conditioning, the city will use deep sea water cooling, which involves pumping cold water from the deep sea into the lagoon, helping to save energy.

7 . Exploring Wildlife Conservation in Kenya

Day 1: Nairobi, Kenya

Arrive at the airport in Nairobi, where our staff will be on hand to drive you to the hotel. Enjoy the rest of the day at leisure.

Accommodation: Tamarind Tree Hotel

Day 2: Lewa Wildlife Conservancy

A charter flight (包机) brings us to Lewa Wildlife Conservancy, a 62,000-acre grassland on the north of Mount Kenya. Considered a model in the conservation field, this healthy wildlife habitat is home to a number of rare species, including the giraffe, the Grevy’s zebra, and African wild dogs. Lewa and the neighboring Borana Conservancy also harbor roughly 15 percent of Kenya’s entire rhino population.

Accommodation: Elewana Lewa Safari Camp

Day 3: Amboseli National Park

Fly by private charter to Amboseli National Park, where vast grasslands are irrigated by underground runoff streams from Mount Kilimanjaro. These landscapes provide a habitat for hundreds of elephants, making the park one of the best places in Africa to spot these large creatures. The travel begins on the drive to Tortilis Camp, set within view of Mount Kilimanjaro.

Accommodation: Tortilis Camp

Day 4: Masai Mara National Reserve

At first light, head out to track the animals that crossed the area during the night. This area has one of the highest concentrations of large predators (捕食性动物) in all of Africa. Then watch large groups of hippos in the Mara River and crocodiles sunbathing on the shore.

Accommodation: Kichwa Tembo Camp
