1 . As newer, more advanced technologies come out, huge amounts of electronics (电子产品) are thrown away, instead of being reused. These goods often end up in landfills, where the chemicals inside them may be a danger to the environment. Electronics can contain harmful materials. If these materials get into the ground or water, the pollution can cause serious problems. Most electronics require metals. These metals must be mined from the Earth. Often the mining process creates serious pollution.
A group known as Waste Electrical and Electronic Equipment (WEEE) Forum is trying to make people more aware of the problems of e-waste. Recently, the WEEE Forum asked researchers from the United Nations (UN) to study a kind of e-waste that’s often not noticed because people don’t consider the goods to be electronics. The WEEE Forum calls this kind “unable-to-be-seen” e-waste.
The UN study shows that about 1/6 of all e-waste is “unable-to-be-seen”. Though it’s “unable-to-be-seen”, it’s certainly not a small amount. The “unable-to-be-seen” e-waste weighs about 9 billion kilograms. The WEEE Forum says that if this e-waste were put into 40-ton trucks and the trucks were then lined up, the line of trucks would be about 5,630 kilometers long.
The surprising kind leading the “unable-to-be-seen” e-waste group was toys. Worldwide, roughly 7.3 billion electronic toys are thrown away each year. These include goods like car racing sets, electric trains, and musical toys. They also include toys with electronic parts, like dolls that speak or games with electronic timers. In all, toys make up about 35% of “unable-to-be-seen” e-waste. But the problem is far larger than just toys. The report also shows that other everyday goods like home alarms, smoke alarms, power tools, and computer cables (电缆) are also big sources of “unable-to-be-seen” e-waste.
The WEEE Forum is hoping that as more people and governments become aware of e-waste, they will make a much greater effort to make sure electronics get reused.

3 . The loss of housing due to floods is an undeniable issue. But now, Japanese housing developer Ichijo Komuten recently unveiled a “flood-resistant house” that can not only remain waterproof during floods, but also float off the ground.
Their new “flood-resistant house” was recently featured on a popular Japanese TV show and it has been getting a lot of attention online ever since. Japan’s TBS TV station recently visited one of Ichijo’s test sites where the company’s new flood-resistant house was being put through a simulated flood. Although it looked just like an ordinary house when the test began, by the time that water started rising around it, viewers could see the structure leave the ground and eventually float a few inches above it.
We’ve all seen floating houses being swept away in severe floods, but Ichijo’s newest invention features a system that prevents just that. The house is connected to a number of thick iron rod(杆)sticking out of the ground with thick cables(缆绳)that ensure it stays in place as the water floods past. When the water recedes, the floating house comes back down in its original position. The “flood-resistant house” also features special vents(通风口))hat close up in the event of flooding, and the plumbing also has special valves that prevent water from getting into the home. Electrical equipment like air conditioning is positioned on the upper half of the building to ensure that water doesn’t reach it.
According to engineers at Ichijo Komuten, most homes flood when water reaches the window level, but because their flood-resistant house can float up to five meters above ground, water is unlikely to reach the windows and everything else is sealed shut.

4 . Nobody expects a natural disaster to strike. Neither does anyone know the impact it can have on life. The following measures can save your life in an emergency.
Typhoon
Typhoons occur in the northwestern Pacific Ocean, particularly in exposed regions like the Caroline Islands, the Philippines, and Japan. The best place to hide during a typhoon is a secure basement or a bathroom with no windows. A must-have device is a battery-powered weather radio, through which you will hear evacuation orders or in other cases, instructions on how to survive in your shelter and learn about the weather situation.
Flood
Floods occur more often than any other natural disaster and change the landscape dramatically. They are usually caused by intense rainfalls lasting for days. Don’t try to be the bravest person around and stay in your house. Once you hear the evacuation warning, leave for safer higher grounds with your important papers in a waterproof container.
Avalanche
An avalanche can hit when you are enjoying Alpine skiing in a dreamlike location. It is very fast and disastrous, burying everything in its way under tons of snow. When an avalanche starts, try to move to the side of the slope as fast as you can. If you get buried in the snow, dig an air pocket to be able to keep breathing. Wait for the rescue team to find you and don’t waste your energy shouting or digging frantically. Call out when you hear the team approaching.
Wildfire
Wildfires spread at an amazing speed and destroy everything in their way. If you are caught in a wild fire, use a wet cloth to cover your nose and mouth to ensure that you can breathe. Try to stay upwind of the fire at all times and get close to a pond or river. Stay low and cover yourself with wet clothing, a blanket, or soil until the fire passes.

5 . Scientists say a huge percentage of bird species are in danger because their habitats, or homelands, are disappearing.
Traditional migration paths take birds through countries that are not protecting the places for birds to stop, rest and feed. The scientists studied the migration or flight paths of almost 1,500 species. They decided that 91 percent of them passed through dangerous areas.
The major danger for migratory birds is development. Buildings and pavements have covered the places where birds stop and feed as they move from one part of the world to another. One of the scientists who worked on the study says “Many of these important places have been lost to land reclamation because of urban, industrial and agricultural land expansion”.
The problem, according to scientists, is that many of these small birds die along their migration paths because they don’t have a safe place to feed and rest. There is no place to restore their energy for the next part of their journey. Countries in North Africa, Central Asia and those along the coasts of East Asia are having the most difficult time in protecting land. The scientists say these countries do not have enough areas that are safe for birds. One species that doesn’t exist now is the Eskimo curlew. “Our world gets poorer every time we lose a species,” one of the scientists says.
The researchers say countries need to work together and come up with safe stopping areas for birds that pass through their boundaries. For example, one country might have preserved safe zones for migrating birds. But a neighbor country might not. A bird might die.
One scientist who is not connected with the report tells Los Angeles Times that while some habitats are changing, more work can be done to make urban areas safe for birds.
He says small changes, like planting more native plants or keeping cats out of the areas birds would be likely to use, could make a big difference.

6 . A new form of real estate(不动产)is appearing along the beaches of South Africa and on the dry islands off its coast-tiny white beach huts. With good ventilation and a sea view, they are just big enough to fit a family of African penguins. Their unique selling point: a safe and cool place for penguins to breed.
African penguins, unlike their relatives that live in snow and ice, live well in the cold currents of the South Atlantic Ocean. But when they come to land, their thick black coat absorbs the heat, and they desperately look for cover-both for themselves and their fragile eggs.
Historically, the penguins dug burrows in layers of guano-accumulated seabird and bat feces- that lined Africa’s penguin colonies, but in the 19th century, traders started selling guano(鸟粪)as fertilizer, leaving the penguins and their eggs increasingly exposed to predators and the baking sun. This, combined with other threats such as egg poaching, overfishing and climate change, has caused African penguin populations to plummet. In 2019, they were thought to be less than 20,000 breeding pairs, down from an estimated 1.5 to 3 million birds in 1900.For more than a decade, the species has been listed as endangered by the IUCN.
To date, the African Penguin Nest Project has installed more than 1,500 nests across five of South Africa’s penguin colonies, and plans to expand into Namibia next year, the only other country with breeding populations of the species.
“This is still just a drop in the bucket,” says Graham, who anticipates they will need to deploy at least 4,500 more ceramic homes to protect penguins currently nesting in exposed areas. “The goal is that every penguin that needs a nest will get one.”

8 . Every year from March to October, Christian Moullec, also known as “Birdman,” takes to the skies aboard his adapted light aircraft. However, the 58-year-old Frenchman’s daily 30-minute flight is not just to enjoy the impressive views, but to guide flocks (鸟群) of lesser white-fronted geese (小白额雁) through safe migration paths which the birds can teach future generations.
His deed began in 1995 when he noticed their declining population in the wilds of Lapland, Sweden. To prevent their numbers from dropping further, Moullec tried to get the threatened species to follow him along migration routes that would protect them from bird hunters.
However, getting grown geese to follow his lead proved challenging. As young geese imitate and follow whomever they view as their parent, Moullec decided to raise the geese from birth.
To help raise funds and awareness of his job to protect not just the geese but birds worldwide, Moullec often allows paying tourists to join him on the 30-minute-long flights aboard his aircraft. In addition to the trained birds flying alongside them, visitors, who come from as far as a 15-hour plane flight away, are treated to a variety of crane and geese species as well as breathtaking views of castles and cities.
He often brings his camera along for the flights, capturing photos not just for their beauty, but for what they describe. Moullec believes the use of agricultural chemicals has done harm to wild European birds, with more than a third disappearing in the last 30 years. “It's a disaster,” he said. “My beautiful images with flying birds should be used to tell this story. ”

10 . Vitamin B could help lessen the effects of the most dangerous type of air pollution，according to a new study published recently. In the first study of its kind，a team of international researchers looked at the damage caused by one of the pollutants that has the most severe impact on health: PM2.5.
Particulate matter，or PM，is a type of air pollutant consisting of small particles of different sizes. PM2.5 has a diameter of fewer than 2.5 micrometers，about 30 times smaller than a human hair. These particles are so small that they can go into our respiratory system (呼吸系统), resulting in lung and systemic inflammation (炎症) and stress.
The team found that something as simple as a daily vitamin B supplement could potentially reduce the impact of the tiny particles on the human body，although they stressed that the research was in its early stages and the sample size was small.
For this study，10 volunteers were initially exposed to clean air and given a placebo (安慰剂) to check their responses. The group then took another placebo for four weeks before being exposed to heavily polluted air from downtown Toronto，where an estimated 1，000 cars pass every hour. The bad air was delivered to the volunteers through an “oxygen－type” face mask. The experiment was then repeated，with each volunteer taking a vitamin B supplement daily made up of 2.5 mg of folic acid，50 mg of vitamin B6，and 1 mg of vitamin B12. B6 can be found in liver，chicken and nuts，and B12 in fish，meat，eggs，milk and some cereals.
The researchers found that four weeks of vitamin B supplements reduced the damage of PM2.5 exposure by 28%－76%. The results highlight how prevention at an individual level could be used to fight the harmful effects of PM2.5.
