1 . What fisherman Moul Thun from a remote island in the Mekong River, in northern Cambodia, didn’t know was that stingray he hooked would eventually be named the largest recorded freshwater fish. For Zeb Hogan, who’s been documenting large freshwater fishes for almost two decades, the discovery of the stingray, which was released alive back into the river, filled him with hope. “It proves these underwater big fish, which are in critical danger, still exist,’’ says Hogan.
Hogan’s pursuit for big fish, called the Megafishes Project and supported by National Geographic Society , began in 2005 when fishermen in northern Thailand pulled a 646-pound cafish out of the Mekong River. The species is known that it was the largest, that is, the heaviest-ever caught in the area.
Arriving at the island, the team found Thun’s fish, a female that appeared to be in good health. It was more than 13 feet from nose to tail. The researchers were shocked to see her weight at 661 pounds. She set a new world record. The original aim of the Megafishes Project was to find, study, and protect the world’s largest freshwater fishes. The project focused on species that could grow to at least the size of a human and that lived only in freshwater.
Hogan initially drew up a list of roughly 30 species to focus on.
The challenge, as Hogan soon learned, was that many of these fish are hard to find. They live in remote, inaccessible places, and often in deep waters. Early on in the search, there were relatively few scientists studying them.
What was clear was that the river giants were shrinking in number, threatened by a host of factors including overfishing, water pollution, and the presence of dams, which block migrating fish from completing their life cycles. As Hogan’s work progressed, its focus increasingly turned to conservation. “It was never about just finding the biggest fish,” Hogan says, “but looking for ways to protect these extraordinary animals that, in some cases, have been on Earth for hundreds of millions of years but are now drifting out of entities.”

You’ve been asking for a while now, so we’re agreeing to it, but there are going to be some rules, OK? This is going to be your dog, not Mommy and Daddy’s, which means you will be taking care of him. And taking care of another living thing is a big responsibility.
It’s going to be your job to feed him, to bathe him and to walk him. If he poops, you’re going to clean it. If your dog gets sick, you’ll have to take him to the vet. If he goes to Doggy Heaven, you will have to bury him. If he happens to be buried in a magic place that causes him to come back to life and become a zombie dog, and I know we may sound like a broken record here, it’s going to be your job to take care of him. Dead or undead, it’s still your concern.
If he kills a deer and drags it to our yard, it’s going to be your responsibility to remove that dead deer. Your pet, your dead deer. If he steps things up and kills a human, perhaps a mailman, as his owner, you might be legally involved in that person’s death. If you try to coverup that death and, in a rush, bury him in the same magic place, bringing him back to life too, don’t scream and cry because a zombie mailman is trying to burst into your bedroom. Your pet, your zombie mailman.
If the zombie mailman kills you, will we be upset? Of course we will. You’re our child. And our child didn’t take her pet-ownership duties seriously enough to predict this sort of thing. If we choose to bury you in the same magic place and allow you to come back to life, well need to make one thing absolutely clear. Just because your human life ends doesn’t mean your human responsibilities end with it. Homework is homework. If the dog’s still kicking around, food/walks/baths you know the drill.
So the answer is yes, you can get a dog. Or just stick with your goldfish. Your call.

6 . Oceans hold a lot of mystery, even for people who study them. But it’s no mystery why they are in trouble. We’ve been using them to hide our waste—such as pouring oil, plastic, and poisonous chemicals into them for decades. We’ve over exploited (开采) many fish stocks to levels so low that they can no longer be harvested.
Oceans are also a primary source of protein for millions of people worldwide. If we want to continue to enjoy what oceans provide, we need to do everything we can to protect them and the life they support. We should ensure the seafood we eat is sustainable.
Of course, not everyone is lucky enough to be able to catch their own fish, which means having sustainable options in the store is critical. As the public’s and companies’ awareness about the risks caused by overfishing and uncontrolled sea farming expansion have grown, food tradesmen in Canada have developed sustainable seafood policies and commitments.
Seafood Progress, an online resource, is designed to help provide rewards for tradesmen and information for seafood lovers. It makes it easier for consumers in Canada to find out tradesmen’s policies on sourcing sustainable seafood, whether they’re sticking to those policies and how they are performing compared to other tradesmen.
But tradesmen must do more to ensure their seafood products are environmentally sustainable and socially responsible. This means expanding the range of their commitments to cover all seafood products they sell in all their stores. It also requires continuing to work with suppliers and producers to improve practices and make sure the sustainable seafood supply meets consumer demand.
It’s no mystery that if we want to continue to eat fish, we must do it responsibly. Seafood Progress has invited seafood tradesmen, suppliers and consumers to join in pushing to this goal.

7 . The dog Pooch Chi Chi managed to open the door and let a fire crew in after his owner collapsed on the kitchen floor.
Responders were searching for another entrance when they heard a “click” as the dog managed to unlock the door to let them in. They found the man, named only as Mr Green, collapsed on the floor in the kitchen as the fire took hold on the hob. Firefighters then swiftly put out the fire and carried out first aid until paramedics (急救医士) arrived.
Devon and Somerset Fire and Rescue Service said “a potential disaster” was avoided with help from the dog. They said they were called to the scene after a smoke detector was activated and a Careline alarm was sounded.
Mr Green initially answered the call but operator at Careline lost communication. Within six minutes, the crew was on scene and investigating. They could hear the alarm but were unable to establish contact with the man inside. With curtains drawn, the crew could not see inside but could hear a dog barking. They tried the front door, but it wouldn’t open. As the crew looked for another entrance, they heard a “click” and the front door opened. The crew went inside to find a man collapsed on the floor in the kitchen when a fire was beginning to take hold on the cooker. They contacted the ambulance service, put out the fire and allowed fresh air in. Firefighters then carried out first aid and stabilised the man until paramedics arrived. It wasn’t until later in the incident that they discovered that Chi Chi had managed to open the front door and let the crew inside.
Ian Bolton, Crew Manager for Home and Partnerships at Devon and Somerset Fire and Rescue Service added: “Having monitored diction in people’s homes means the fire service are only minutes away from providing lifesaving assistance. This is a real success story and highlights the importance of Careline and the fire service. Careline’s system, combined with the speed of our crews getting to the incident, saved Mr Green’s life. The cherry on the cake, however, was Chi Chi letting the crews in before they had to force entry to the property.”

8 . A lunch break—it’s an important and often necessary part of our working or school day. And now we’re spoilt (惯坏) with a lot of places to buy our lunch from, all offering attractive dishes and sandwiches to eat on the go.
But our appetite for buying our lunchtime fare is not just costing us money, there might be a cost in terms of damaging our planet too. Just grabbing a sandwich, crisps and maybe a cake and coffee can produce at least four items of waste. Paper boxes, cups, wrappers and plastic knives and forks are all part of our disposable feast in addition to the food waste we create. Some experts say throwing away food, which produces methane as it rots, is a bigger cause of climate change than plastics.
But regardless of what causes the most damage, the solution, according to an environmental campaign group called Hubbub, is to eat packed lunches. Tessa Tricks from the group says, “People are saying that they are buying food to take out because life has got busier.” And she says people think they are being more efficient; but she argues that it’s usually healthier and cheaper to make your own lunch. It means you can eat the things you really want and make the quantity that you actually need.
Of course, preparing your lunch is another thing to fit into your morning scramble (忙乱) of getting ready for work, so if you haven’t got time and you are going to buy lunch, an alternative that Hubbub suggests is to take your own container to a shop and ask them to put your food in it. The idea of using reusable coffee cups for hot drinks and refilling water bottles has already proved successful, so this could be another step in the right direction.

10 . Margot doesn’t have a garbage can. It doesn’t need one because Margot simply doesn’t cause anything to get thrown away. The restaurant doesn’t allow any type of single use plastic. Margot, which opened last year, is one of the small but growing restaurants around the world aiming to avoid not only food leftovers, but also any garbage.
“Food waste has been increasing as an issue for restaurants over the last 10 years,” says Calvin Brown. He runs the Sustainable Restaurant Association. Based in the United Kingdom, the organization helps food business become more environmentally responsible. He says that food waste contributes to releasing the greenhouse gas, so there is strong motivation to reduce waste and help the environment.
In the USA, food waste and packing account for nearly half of the material sent to landfills. Restaurants from McDonald’s to Starbucks are addressing this issue with “no straw Mondays” and limits on single-serving plastic, but a handful of restaurateurs are trying to get rid of rubbish entirely. There’s also economic case to be made for waste reduction. One study shows that restaurants save seven dollars for every dollar invested in anti- waste methods.
Avoiding food waste is the first and perhaps most obvious challenge for sustainable restaurants. Doug McMaster, chef at Silo in London, only serves a set menu. This removes the worry that one particular item won’t sell well, and will spoil in the refrigerator. Compost (堆肥) is a necessity as well. Nolla (meaning “zero” in Finnish) in Helsinki, Finland is giving compost to its suppliers as well as its diners. Nolla also has food- tracking software more commonly used among corporate food service companies to keep track of what sells and what rots.
Sometimes restaurants call themselves environmentally friendly, but they might just be using the label. Calvin offers some pointers on what to look for to make sure a restaurant is truly committed to sustainability.
