I'm hardly alone, which is bad news for the world's oceans. Partly because more and more sushi is demanded, we're fast fishing out our seas. Some researchers estimate that if we don't change the way we harvest the oceans, all the commercial fisheries (捕鱼业) in the world could disappear as early as 2048. That could mean no more fish to buy in your local supermarket.
Fortunately, scientists are looking for ways to fish sustainably (可持续地). One method is a quota system that sets a limited amount to every fisherman or corporation who wants a share of the total catch for certain sea area. These catch shares get rid of the possibility to over fish.A recent study in Science found that the system can prevent fishery from dying and even make it better over time. "It's truly a win-win situation," says Steven Gaines, a marine biologist at the University of California at Santa Barbara and one of the study's co-authors.
Consumers also can help save the seas through the fish they buy. California's Monterey Bay Aquarium Institute is coming out with pocket guides to sustainable sushi. The researchers base their ratings on the health of a wild fish's population as well as the impacts of fish-farming operations. Oysters, for example, grow fast and can be farmed sustainably, but salmon can't. The researchers also take fishing practices into consideration: catching big-eye tuna (金枪鱼) can cause its nearby fish to die, which certainly no one wants to see. It is hoped that, by making the right choice, consumers can encourage businesses to fish in a more sustainable way.

American Dreams
There is a common response to America among foreign writers:the US is a land of extremes where the best of things qre just as easily found as the worst.This is a cliche(陈词滥调).
In the land of black and white,people should not be too surprised to find some of the biggest gaps between the rich and the poor in the world.But the American Dream offers a way out to everyone.(46) No class system or govemment stands in the way.
Sadly,this old argument is no longer true.Over the past few decades there has been a fundamental shift in the structure of the American economy.
The gap between the rich and the poor has widened and widened.(47)
Over the past 25 years the median US family income has gone up 18 per cent.For the top 1 per cent,however,it has gone up 200 per cent.Twenty-five years ago the top fifth of Americans had an average income 6.7 times that of the bottom fifth.(48)
Inequalities have grown worse in different regions.In California,incomes for lower class families have fallen by 4 per cent since 1969.(49) This has led to an economy hugely in favor of a small group of very rich Americans.The wealthiest 1 per cent of households now control a third of the national wealth.There are now 37 million Americans living in poverty.At 12.7 per cent of the population,it is the highest percentage in the developed world.
Yet the tax burden on America’s rich is falling,not growing.(50) There was an economic theory holding that the rich spending more would benefit everyone as a whole.But clearly that theory has not worked in reality.
A.Nobody is poor in the US.
B.The top 0.01 per cent of households has seen its tax bite fall by a full 25 percentage points since 1980.
C.For upper class families they have risen 41 per cent.
D.Now it is 9.8 times.
E.As it does so,the possibility to cross that gap gets smaller and smaller.
F.All one has to do is to work hard and climb the ladder towards the top.
The immediate problem is poverty. Most of Africa is urbanising at a lower level of income than other regions of the world did. That means there's little money around for investment that would make cities liveable and more productive. Without upgrades and new capacity, bridges, roads and power systems are unable to cope with expanding populations. With the exception of South Africa, the only light rail metro system in sub-Saharan Africa is in Addis Ababa, Ethiopia. Traffic jam leads to expense and unpredictability, things that keep investors away.
In other parts of the world, increasing agricultural productivity and industrialisation went together. More productive farmers meant there was a surplus that could feed cities; in turn, that created a pool of labour for factories. But African cities are different. They are too often built around consuming natural resources. Government is concentrated in capitals, so is the money. Most urban Africans work for a small minority of the rich, who tend to be involved in either cronyish (有裙带关系的) businesses or politics. Since African agriculture is still broadly unproductive, food is imported, consuming a portion of revenue.
So what can be done？ Though African countries are poor, not all African cities are. In Lagos, foreign oil workers can pay as much as 65,000 dollars per year in rent for a modest apartment in a safe part of town. If that income were better taxed, it might provide the revenue for better infrastructure. If city leaders were more accountable to their residents, they might favour projects designed to help them more. Yet even as new roads are built, new people arrive. When a city's population grows by 5% a year, it is difficult to keep up.
