1 . Unlike other natural disasters such as hurricanes, earthquakes are very hard to see coming, even for scientists.
Drop, cover and hold
If you feel the ground start to shake, drop, take cover under as table piece of furniture, and hold on. You can hide under something like a desk or table, with one arm holding on to a leg of the table and your other arm protecting your neck and head.
Make a family plan
Secure your furniture
Those hanging shelves above your bed could be a danger during an earthquake. People often get injured from “flying or falling objects” like furniture or glass during earthquakes. So examine your home and ask yourself, “What could be a potential danger to my safety?”

3 . The streets of Cotonou, Benin’s largest city, have been Domingo Soule’s workplace for 35 years. The 50-year-old motorcycle taxi driver spends his days driving for miles on roads blanketed in exhaust fumes (尾气), picking up customers and taking them to where they want to go. But Soule has developed a cough from breathing in air pollution, he believes, and at the end of each day his eyes hurt.
Things maybe about to change, however. In recent months, he’s seen more and more electric motorbikes on the streets of Cotonou. The Indian manufacturer (制造商) M Auto introduced its electric bikes in Benin in July 2022 and there are already 2,000 on the roads; an additional 2,000 people have paid deposits (定金) and are waiting for delivery.
Shegun Bakari, M Auto’s chief executive, has ambitions to get all moto-taxi drivers in Benin to switch to electric. This month he plans to launch a campaign to encourage them to swap (交换) their old bikes for new electric models.
The only sticking point is the battery. M Auto’s business model relies on “swap stations” throughout the city. When the battery runs out after about 60 miles, drivers must visit a station and pay to exchange the empty battery for a full one. Concerns about the battery are also preventing Soule form buying an electric bike. It could cost him 4,000 CFA ￡(5.40) a day to replace batteries, Soule says, whereas at the moment he can buy five litres of petrol (enough for one day) for 3,000CFA.
Bakari understands his concerns. In Beni, close to 40% of the population live under the poverty line, earning less than US$2 a day. “If I’m living with $2 a day, I can’t afford to pay more just because I want to save the planet,” he says.
He and his team are working to persuade governments in Africa to reduce taxes on electric vehicles, as well as putting plans in place to produce the electric bikes in Benin. They are also in talks with the government to build a solar plant to provide the extra energy that will be needed.

4 . Throughout history, many species of animals have been threatened with extinction. When Europeans first arrived in North America, more than 60 million buffalo (水牛) lived on the continent. Yet hunting the buffalo was so popular during the 19th century that by 1900 the animal’s population had fallen to about 400 before the government stepped in to protect the species. In some countries today, the elephant faces a similar challenge, as illegal hunters kill the animals for the ivory in their tusks.
Yet not all animals with commercial value face this threat (威胁).The cow, for example, is a valuable source of food, but no one worries that the cow will soon be extinct. Why does the commercial value of ivory threaten the elephant. while the commercial value of beef protects the cow?
The reason is that elephants are a common resource, while cows are private goods. Elephants wander freely without any owners. The hunter has a strong motivation to kill as many elephants as he can find. Because illegal hunters are numerous, each has only a slight motivation to preserve the elephant population. By contrast, cattle live on farms that are privately owned. Each farmer makes great effort to maintain the cattle population on his farm because he harvests the benefit of these efforts.
Governments have tried to solve the elephant’s problem in two ways. Some countries, such as Kenya and Uganda, have made it illegal to kill elephants and sell their ivory. Yet these laws have been hard to put into effect, and elephant populations have continued to dwindle. By contrast, other countries, such as Malawi and Namibia, have made elephants private goods and allowed people to kill elephants, but only those on their own property.
With private ownership and the profit motive now on its side, the African elephant might someday be as safe from extinction as the cow. The ancient Greek philosopher Aristotle pointed out the problem with common resources: “What is common to many is taken least care of, for all men have greater regard for what is their own than for what they possess in common with others.”

5 . When a leafy plant is under attack, it doesn’t sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short.
Scientists have found that all kinds of plants give out VOCs when being attacked. It’s a plant’s way of crying out. But is anyone listening? Apparently. Because we can watch the neighbours react.
Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the tables are turned. The attacker who was lunching now becomes lunch.
In study after study, it appears that these chemical conversations help the neighbors .The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.
Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to “overhear” the cry. So information was exchanged, but it wasn’t a true, intentional back and forth. Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate (亲密的) than the world we can see and hear. Our senses are weak. There’s a whole lot going on.

7 . 4 Best Places to Travel in 2023
2023 is the year when travel returns in a big way. To get you started, we’ve rounded up some of the best places to travel in 2023. All you need to do is pick the place that appeals to you.
Copenhagen
With its fantastic houses, clean streets and colorful architecture, Copenhagen is regarded as the most livable city on the earth. Named the World Capital of Architecture for 2023, Copenhagen will offer a series of major artistic events and programs sure to delight architects and design lovers.
Bhutan
For travelers with a sense of adventure and a love of discovery, Bhutan has always been a must-go destination. In 2023, travelers can once again explore the Trans Bhutan Trail, which runs 250 miles from east to west, offering visits to the century-old communities along the journey. The trail spans (横跨)18 major bridges and national parks and connects more than 400 historic and cultural sites.
Bordeaux
The coming years will be sporty in the historical wine region of Bordeaux in France. In 2023, the city will host the Rugby World Cup, an intense and stressful game. Beyond sports, Bordeaux is one of the favorite historical cities, with more than 350 structures that are either nationally or regionally listed as historical monuments.

8 . The Seychelles — that remote island chain off the coast of northern Africa is heaven for scuba divers (水肺潜水). With more than 100 islands, most of which are uninhabited, and a relatively small amount of tourists impacting the oceans and beaches, the Seychelles has some truly best scuba diving.
Fisherman’s Cove Reef
If you’re a beginner diver who loves gentle drop-offs and sea turtles, make sure Fisherman’s Cove Reef is on your scuba diving radar. The site is very popular as there’s rarely a current, it’s very shallow, and has a colorful reef with everything from eagle rays to small leaf fish, which can be very difficult to find against the seagrass and coral.
Ennerdale Wreck
If you love wreck diving, head right for the Ennerdale, a British oil tanker that accidentally sunk in 1970. Because of the medium-to-strong current and depth, it’s for divers with advanced open water cert. They’ll be able to swim around the wreck’s propellers, penetrate the frame, and likely see reef sharks and the occasional bull shark.
Baie Ternay Marine Park
The shallow, protected area of ocean has healthy and varied coral, and a lively reef. Both snorkelers and beginner divers are likely to see sea turtles grazing on the seagrass, coaching reef fish, and small eels poking out of the sandy ocean floor.
Aldabra Atoll
It doesn’t get much more remote than the Aldabra Atoll, a UNESCO site. The coral reef continues underwater, which makes all the island’s dive sites stunning. Advanced divers can do drift dives in a channel with a chance of seeing sharks, while beginners can stay closer to the reefs, checking the various species of marine life in the Indian Ocean off their must-see list. The island is home to nearly 100,000 giant tortoises, as well as several other rare species
