6 . Amsterdam, with its scenic canals lined with picturesque, 17th-and 18th-century buildings, a major European tourist destination, is slowly collapsing.
Sinkholes are appearing in small streets, and nearly half its 1,700 bridges are unstable and need repairs. The fundamental problem is the state of the canal walls: about 125 miles of them are so broken that they are in danger of collapsing into the canals, potentially taking buildings and people with them. As a huge project to shore up the canal walls gets underway, the city is beginning to look like one huge construction site.
Like much of the Netherlands, Amsterdam lies below sea level. Built on a swamp and heavily expanded in the 17th century, the city sits on millions of wooden piles that serve as foundations. As modern life changed the city, many houses were strengthened with concrete, but the foundations of streets and canal walls were ignored. Many of the wooden piles have shifted, cracked or collapsed under the pressure, causing bridges and can al side walls to sink and crack. Water then seeps in, washing away mortar(砂浆), further hollowing out the infrastructure and creating sinkholes.
The alderman, Mr. De Vries, said that if the city had continued to ignore the problem, it would have headed straight for a catastrophe. The reconstruction will take at least 20 years and will cost 2 billion euros, perhaps even more. “These are big numbers, and work needs to take place in a very busy, closely-populated area,” Mr. De Vries said. “People live here and work here, and we usually have many tourists.”
He acknowledged that Amsterdam in the coming years would look different from its usual postcard self. Still, he insisted that tourists should not be discouraged from visiting. “We invite everyone to come and see what we are doing,” he said. “We want visitors to realize that such a magnificent city needs maintenance.”

7 . The Amazon Rainforest is the largest rainforest in the world. This extraordinary tropical jungle is roughly the same size as 48 states in the U. S. The Amazon surrounds the Amazon River and its many tributaries. The Amazon River is the largest river in the world by volume discharged. It stretches 4, 225 miles — from the peaks of the Peruvian Andes to the beautiful beaches of Brazil.
Scientists estimate there are 390 billion trees in the Amazon Rainforest, including over 16, 000 species. The Amazon supports at least 427 mammal species, 3, 000 species of freshwater fish, over 1, 300 species of birds, 378 types of reptiles, and 400 species of amphibians. Notice how we didn’t mention any invertebrates (无脊椎动物), like insects and arachnids? That’s because the Amazon’s gargantuan population of invertebrate species climbs well into the millions. And that only includes the species we’ve identified so far!
But how does this giant ecosystem support so many diverse organisms? Scientists divide the Amazon into four ecological layers: the forest floor, the understory, the canopy and the overstory. Each layer plays an important role in the health and survival of the rainforest. The forest floor is where the rainforest finds its humble beginnings.
The roots of towering trees grow in thick, low-nutrient soil laid over a layer of volcanic rock. Without deep, rich soil, the forest floor’s tropical vegetation depends on decomposers (分解物), like bacteria, fungi (真菌) and insects. These essential organisms pull nutrients from dead organic material, like leaves, wood, and animal bodies.
Vital for nutrient cycling, vigorous mushrooms, like the scarlet cup and the veiled lady, decorate the forest floor. Some of these fungi can give out light. When the sun sets over the Amazon, these radiant mushrooms light the forest floor like magical nightlights. Very little sunlight penetrates (穿透) the upper layers of the rainforest, so the forest floor remains dark and damp year-round.

10 . Last fall, the Great Salt Lake hit its lowest level since record keeping began. The lake sank to nearly six meters below the long-term average. The lake’s shrinking threatens to upend the ecosystem, disturbing the migration and survival of 10 million birds, including ducks and geese.
Duck hunters aren’t the only ones worried about the Great Salt Lake. The decades-long decline in lake level is raising alarm bells for millions of people who live in the region. The low lake level and increasing salts in the lake water threaten to destroy economic mainstays like agriculture, tourism and mining. Exposed salts can also reduce air quality and so threaten public health.
Saline lakes (咸水湖) are terminal lakes. They have no rivers flowing out of them. As water disappears, salts are left behind. At the same time, the people who live in these deserts use freshwater for crops, homes and industry. Residents get water from streams and rivers into canals, pipelines or reservoirs before it reaches the lakes. And as the lakes shrink, the salt in water increases.
Lake Poopo, a highland lake in Bolivia that used to stretch 90 kilometers long and 32 kilometers wide, is now a salty mud flat. The Aral Sea shared by Kazakhstan and Uzbekistan, once the world’s fourth largest lake, has at times in recent decades shrunk to a tenth of its historic 68,000-square-kilometer surface area. Some saline lakes, like Nevada’s Winnemucca Lake, dried up so long ago — the waters that fed it were led to agricultural fields — that most people have forgotten they were ever wet.
The good news is that people still have time to halt the Great Salt Lake’s decline by using less water. Cutting agricultural and other outdoor water use by a third to half through a combination of voluntary conservation measures and policy changes would allow the lake to refill enough to support the region’s economy, ecology and quality of life. If this succeeds, the Great Salt Lake can be a model for how to save other saline lakes around the world.
