2 . Dear Doggy Diary

Now we’ve surely got all we require for the puppy’s arrival: a basket, a screaming toy banana and a bag of dog food. For names, we are hesitating between Spike or Lenny—but, as I tell this list to a Black friend, I suddenly realize both names are associated with famous Black men, and panic that this is a little offence.

Our friend Sam has kindly volunteered to “puppy proof” our home. “You don’t want to give him that screaming toy, that’s encouraging him to eat your sofa,” she says, inspecting our purchases disapprovingly. She hands us a book, by Dr Ian Dunbar. “This guy”, she assures us, “is a Super Babysitter for dogs.”

Spent last night ______57______ Dunbar has plenty of wisdom on “positively communicating” with the puppy, but nothing on how to get a puppy and also two young children.

D-Day. Now the registration website wants a dog name at short notice. So, we go for “Buzz”. One syllable (音节) and with multi-generational fascination (Granny thinks Aldrin, kids think Lightyear).

I feel very hesitant about saying so, but last night went well. Buzz is incredibly cute, the kids adore him and he’s very cute and only did one pee (排尿) on the blanket, and did I mention he’s cute?

“Love” feels like a stretch right now. Our “play” was evidently not “focused” enough to prevent Buzz biting through our sofa. Also, our three-year-old thinks it’s funny to run away, so Buzz wrestles him to the ground and licks all over his face. I suspect this isn’t the best way to prepare Buzz for engaging with the public.

The whole house smells of dog. I find this nasty, but friends, family, and people we barely know existed are dropping by to meet him. “It’s like having a baby, eh?” says my neighbor, Erik, brightly. “Yes, but it’s a baby you can neglect when it cries!” I respond cheerfully. He frowns (皱眉).

It’s 2 A.M. on the coldest day of the year and I’m on my hands and knees in the bushes. I think you’ve never really experienced a harsh mid-winter until you’re trying to run after a puppy. Then, we return inside, and it’s just me and Buzz. Peace. I should put him back in his cage, but I find I can’t resist a hug. Don’t tell my wife.

4 . Farmers in southern Italy are cultivating tropical fruits like avocados and mangos. Tropical creatures such as the rabbitfish are ____ in Mediterranean nets. And the winemakers in southern France are worried that their grapes may become extinct. Fifty years ago all this would have been _____ , but since the early 1980s rising temperatures have forced some farmers to ____ grapes for some tropical fruits.

Italy and France have long been proud of their cuisines. Both countries jealously ____ the rules that say   only ham made in Parma, a province in northern Italy can be called “Prosciutto di Parma”, and only fizzy wine made in Champagne can be called champagne.

Roquefort, that most ____ of blue cheeses, was given special protection by the parliament of Toulouse in 1550. The fact of having been grown somewhere famous has traditionally been seen as a guarantee of ____ .

But climate change could ____ that. Take polenta(意大利玉米糊), a popular Italian dish consisting almost entirely of ground corn. High temperatures and drier weather have already reduced corn yields in southern Italy.

If this pattern continues and spreads ____ , will Italian polenta-makers have to order their corn from elsewhere? And what about durum wheat, which grows ____ in Mediterranean lands and is used to make pasta, flatbreads and couscous? Modelling suggests that durum yields will sharply fall there if the temperature keeps on rising.

So should we worry about the future of spaghetti? Gabriele Cola, a researcher at Milan University, is   ___ about the short term. “I don’t see crops at serious risk, because farming is more ____ and technologically capable, so it can always respond to changes,” he says.

Increased irrigation(灌溉) can ____ the effects of drought. Scientists may also breed more resistant varieties of crops. But ____ deeper change seems likely. If temperatures continue to rise, farmers in northern   Europe may find they can grow southern staples( 主食 ); polenta may ____ northern Europe. Meanwhile, the Italian southerner may also have to ____ if tropical fruits continue to spread there.

5 . Do animals have feelings?

People often assign feelings to animals. That zoo polar bear’s vacant stare must mean he’s sad. The uh-oh expression a dog flashes after knocking over the garbage indicates shame. But scientists haven’t determined whether these human-like expressions really mean anything. After all, it’s very difficult to read a dog’s mind.

Scientists believe that certain brain cells in humans called spindle cells (棱形细胞) are responsible for human social behavior and the interplay between thoughts and feelings. Studies have revealed that chimpanzee, dolphin and whale brains also possess spindle cells.     1    

Even animals that don’t have spindle cells, such as dogs, have shown behaviors that can suggest a human-like social sense.     2     Scientists report that this shows dogs are sensitive to human social cues and are able to correctly interpret them. Still, this only proves that dogs know how to find food, not that they have feelings.

Observations of apes have also revealed behavior that appears to represent various human-like desires. In some tests, chimpanzees demonstrate what looks like altruism (利他主义) helping their own kind and even other species without the expectation of a reward.

    3     In a recent study, a Barnard College researcher tested dogs to see if their guilty looks were linked to actual bad behavior. Dogs were tempted with a treat and told by their owners not to eat it. The dog’s owners weren’t allowed to see whether their pets had eaten the treat or not, but were told either that they did or that they didn’t, and were then instructed to scold the dogs that disobeyed. The experimenters noted that scolded dogs showed a guilty look whether or not they had actually done wrong.

    4     A guilty look suggests a feeling of guilt in a human but not necessarily in a dog, according to the Barnard research. Similarly, even apparent empathy (共情) behavior might not actually mean these feelings are present in the brains of animals.

6 . How did Cape Town, South Africa, get into a Day Zero situation—when the city’s taps would go dry because its reservoirs (水库)would become dangerously low on water? The city gets its water from six reservoirs in Western Cape province, which usually ____________ during the rainy season, from May through August. But since 2015 the region has been suffering from the worst drought (干旱)in a century, and the water in those reservoirs____________ tremendously. Compounding the problem, Cape Town’s population has grown substantially, increasing ____________ . The city actually did a pretty good job by reducing leaks in the system, a major cause of water waste, and has even won awards for its ____________ policies. But the government of South Africa was slow to declare a national disaster in the areas hit hardest by the drought, paving the way for the recent ____________.

Cape Town is not ____________ . Since 2014 southeastern Brazil has been suffering its worst water shortage in 80 years,___________ decreased rainfall,   forestation and other factors. And many cities in India do not have access to municipal water for more than a few hours a day, if at all.____________ , the city of Shimla ran out of drinking water in May, urging locals to beg tourists to stay away from the popular Himalayan summer resort.

In the U.S., the situation is somewhat better, but many urban centers still ____________ water problems. Californians recent multiyear drought led to some of the state’s driest years on record. Since about half of the state’s urban water usage is for landscaping, it was able to cut back on that fairly easily. But cities that use most of their water for more essential uses, such as drinking water, may not be so ____________ .

____________ , steps can be taken to avoid urban water crises. In general, a “portfolio approach” that relies on multiple water sources is probably most ____________ . Cape Town has already begun implementing a number of water projects, including tapping groundwater and building water-recycling plants. Many other cities will need to repair existing water infrastructure (基础建设)to cut down on leakage. City leaders should be thinking about meeting long-term needs rather than just about ____________ requirements. Good organization and financial accountability are equally critical. And planning efforts should include diverse stakeholders (利益相关者)from the community. One major challenge is providing services to informal areas, which develop without any government foresight. Such regions often ____________ basic resources一a well-planned water supply among them. The global community has an opportunity right now to take action to prevent a series of Day Zero crises. If we don’t act, many cities may soon face a time when there isn’t a drop to ____________ .

9 . Greening the blue

Is there a “natural” way to enhance the potential of the oceans to lock away climate-warming CO₂? Planting more trees on land can help draw down more CO₂ from the atmosphere—the basis of many plans for carbon credits that companies buy to offset their emissions (抵消其排放).     1     Seaweed forests and saltmarshes (盐碱滩) are common examples.

Some regard the potential for this “blue carbon” as huge, although as yet there is no mechanism for integrating it into carbon offsetting plans. John Virdin of Duke University in North Carolina says, “    2    ” He adds, “You have to go out and measure all the carbon that’s there, you have to show that it’s not going to be lost, you have to keep monitoring it.” Virdin and others have proposed extending an existing land-based plan called REDD + (reducing emissions from deforestation and forest degradation) to the ocean, but that is an idea whose ship has yet to sail.

    3     In March, the UK government’s climate adviser, the Climate Change Committee, found that restoring and creating seagrass and saltmarsh ecosystems in the country would only lock away a small amount of CO₂, removing “well below” 1 million tonnes a year. Nonetheless, these are efficient carbon stores according to the committee.     4    

10 . More than three billion people rely on the ocean to make a living, most of whom are in developing countries. As the global population increases, the demand for seafood is expected to rise, too.

Although ocean ecosystems are stretched to the limit by climate change, overfishing and more, studies nevertheless suggest that seafood can be expanded sustainably to meet future food demands. Success will depend on small-scale fisheries. These fisheries can be remarkably efficient. Almost everything that hand-to-mouth fisheries catch is consumed. By contrast, around 20% of the fish caught by industrial ships is estimated to be wasted, mainly because of unwanted by-catch.

Small fishers rarely have the right resources to expand their operations, or even to survive. If they do scale up, they might lose some of their current advantages or engage in the same harmful practices as do large commercial fisheries. Managed with care, however, small fisheries could provide win-wins for livelihoods and the environment.

Most nations already have management policies for marine ecosystems that provide for small-scale fisheries. But small-scale fishers’ rights to access are often poorly defined, ineffectively enforced or unfairly distributed (分配). Government subsidies (补贴) also require reform. One estimate found that large-scale fishers receive about 3.5 times more subsidies than small-scale fishers do. Instead, subsidies and other funds should be directed towards small-scale fishers to let them expand their access to markets, while keeping them from adopting the negative practices of large-scale operations.

The total global loss and waste from fisheries is estimated at between 30% and 35% annually primarily due to a lack of technology, good manufacturing practices, and infrastructure such as decent roads and cold storage. Public and private investment in cold-storage facilities and processing equipment could help. One promising strategy is to pair international or national funding with direct contracts for feeding programmes linked to schools, hospitals and similar facilities. Such arrangements would provide small fisheries with large, consistent markets and storage infrastructure that boosts local consumption and does not incentivize (刺激) overfishing.

Moreover, simple incentive programmes could be conducted by funders, managers and local governments trying to promote sustainable fisheries. For example, local markets could display a rating system for individual fishers or small fisheries. This could include various elements of sustainability other than environmental ones — such as providing information on the type of fishing equipment, location of the catch and freshness. Promoting the rating as a social responsibility concept would inform consumers of the need to support sustainable fisheries.

Anyway, only joint problem-solving efforts can deliver seafood protein, sustainably, to a world that increasingly needs it.
