Plastic pollution has long been a problem, but now it has got to a new height.
Micro-plastics, plastic particles (颗粒) less than 5 millimeters, have been found on Mount Qomolangma as high as 8,440 meters above sea level, according to a recent study in One Earth, “These are the highest micro-plastics ever discovered so far,” lead writer Imogen Napper from the University of Plymouth, UK, said.
Scientists collected snow and water samples from 19 different locations from 4,200 meters above sea level all the way up to the top of Mount Qomolangma. They found micro-plastics in all the water samples and part of the snow samples. The most polluted sample was from the Base Camp in Nepal, where there are many human activities. It had 79 particles of micro-plastics per liter (升) of snow.
But how can they get there? The answer is human activities. It is climbers who bring plastic products to the mountain. Even if they don’t litter, just walking for 20 minutes or opening a bottle of water can send micro plastics into the environment.
The plastic pollution has reached the most distant places on Earth. Researchers even found a plastic bag at the deepest point in the world’s oceans—the Mariana Tench (里业纳海沟). The bag is the same as the ones commonly used in stores.
Even covered in ice, the Arctic is still polluted by plastic. A 2020 report in Nature suggests that there are 2,000 to 17,000 plastic particles per cubic meter in Arctic ice (冰芯), and between 0 to 18 plastic particles per cubic meter from the water under the ice. Experts think micro-plastics may be transported by air and then reach the North Pole in snowfall.
We don’t know the potential (潜在的) problems these plastic particles would bring to the environment and our health, said a scientist. Then what can we do? We need to turn to high technology, like using new environment-friendly materials instead of plastic when possible.

 | A big welcome to our new baby black rhino, Tau! |
Tou was born last month. He weighs 40 kg now. He hasn’t got any horns at the moment. They’re starting to grow. | |
| Black rhinos are huge. They’re brown, grey or white. They aren’t block! They’ve got two horns. They’re the only animals with horns on their nose. They can’t see very well, but they’ve got a better sense of smell and hearing than many animals. Black rhinos live in the south of Africa, in the sovannah, in woods or near rivers. They eat in the morning and evening. At midday, when it’s hot, they like to lie in water or mud. Every baby rhino is important, because rhinos are in danger of extinction. 200 years ago there were about 1,000,000 rhinos in Africa. Now there are less than 5,000. Sadly, baby rhinos often die in the wild. Baby rhinos born in zoos are safe. Every baby means a better future for block rhinos. |
| A．Tau weighs 1,000 kg without any horns now. |
| B．Rhinos can find food easily with good eyesight and smell. |
| C．Black rhinos prefer to stay in wet places, especially in hot weather. |
| D．Black rhinos are one of the large animals which have horns on the noses. |
| A．To explain rhinos have many babies. |
| B．To call on more people to visit them. |
| C．To show all rhinos should live in the wild. |
| D．To tell why people keep baby rhinos in zoos. |

We live on Earth. It’s our home. But how much do you know about it? Let me tell you something about our Earth. The Earth is like a huge ball. Like the other seven planets（行星）, the Earth is running around the sun. It’s the third nearest one to the sun. It takes the Earth about 365 days to run around the sun. At the same time, the Earth is going around itself. If you are in space, you can see lots of white clouds over the surface（表面）of the Earth. Through the clouds, you can see the blue colour of the oceans, and the brown colour of the land. About 70% of the Earth is covered with water. Why do we have day and night? When the half of the Earth is facing the sun, it’s daytime. As the Earth turns, and this half is away from the sun, night is coming. And it’s daytime for the other half.

Have you ever bought Genki Forest sparkling water because it’s advertised as “sugar-free”? The company recently said that they were sorry for a misleading advertisement.
The company said the drinks are “sucrose-free”, but this is not the same as “sugar-free”? Now the company has changed the word “sugar-free” to “low sugar” on the bottle.
In fact, there are many kinds of sugar, Sucrose in just one of them. Other kinds of sugar, such as Iructose and sugar alcohol, are still in Genki Forest drinks. These types of sugar are used as sweeteners. They offer little energy, but a small amount of them can make drinks taste sweet. That’s why low sugar drinks like Genki Forest are popular who want to lose weight. They believe that they can not only enjoy sweet drinks but also avoid taking in too much sugar.
However, studies find that the sweeteners might make people eat more. When you eat sweet-tasting things, they send your brain a “sweet signal”. Then your brain tells your body to prepare itself to take in energy. But since the low-sugar soft drink has little energy, the brain will not receive what it is expecting. At this time, you will feel hungry and start getting energy by eating more food.
According to China Daily, drinking too many low-sugar drinks might lead to fatness and many other diseases. It’s time for you to think twice when you want to keep up with the fashion.
