What would you think if someone suggested knocking down St Paul’s Cathedral to widen the road? Or pulling down Big Ben to make way for a car park? It would be ridiculous, right? But when it comes to devastation of the natural world, we aren’t so easily shocked. But we should be…or we’ll be in a lot of trouble.
Nature is shrinking by the day. Ancient forests are destroyed. Wetlands are becoming dry. Woodland is disappearing, and all in the name of progress. This is bad in itself, but it’s devastating for biodiversity.
Biodiversity refers to the variety of plants, animals and other living things that are all interconnected. The ecological services provided by biodiversity are vital to everyday life. The air we breathe is a product of photosynthesis by green plants. Insects, worms and bact
eria break down waste and make soils rich. And tiny organisms clean the water in rivers and sea. In fact, all life on the earth exists thanks to the benefits of biodiversity. More than 90 percent of the calories consumed by people worldwide are produced from 80 plant species. And 30 percent of medicines are developed from plants and animals. Maintaining a wide diversity of species in each ecosystem is necessary to preserve all living things.
The loss of biodiversity could be devastating. “It is wrong to think that biodiversity can be reduced indefinitely without threatening humans,” said Harvard University biologist Edward O. Wilson, known as the “father of biodiversity”. He warned, “We are about to reach a critical point beyond which biodiversity loss will become irreversible.”
But what can we do? The present problem is that the concept of biodiversity is so vague. People might care about giant pandas, but it is much harder to excite them about the fate of tiny sea creatures which are being boiled to death in the cooling systems of power stations along coastlines. The Guardian newspaper is trying to help. It has launched the B
iodiversity 100 campaign to try to convince governments around the world to take action to deal with the widespread concerns about biodiversity. This includes persuading the UK government to create a series of marine reserves to reserve the decrease in the sea-life caused by industrial fishing, stopping fishing sharks by the Japanese fishermen and banning the killing of dingoes in Australia, among many other things.
There is a lot to do. And we’d better act quickly if we don’t want to end up with a planet that can’t sustain life!

Despite being used by 1.34 billion people each year, traveling on the Tube in London can actually be quite lonely. An unwritten rule encouraging silence, mixed with classic British reserve, means that even though you’re packed into an enclosed space with hundreds of other people, the morning commute (上下班的路程) can leave you feeling somewhat disconnected.
An American living in London, however, is trying to change this. “You get on the Tube here and it’s completely silent and it feels a bit strange,” says Jonathan Dunne, 42, who has started a worldwide dialogue after giving out badges (证章；徽章) with the words “Tube chat?” last month, encouraging commuters in London to get talking to one another.
“I handed out 500 badges during rush hours in a city of 8 million, expecting most of them to be thrown away, but after about 24 hours it completely snowballed,” he says.
Dunne and his “Tube chat” campaign have been covered by media across the world since then, seeing TV interviews in Sweden, Brail and the UK, as well as a lot of website, newspaper and magazine appearances. Although Dunne says he’s received mostly positi
ve feedback, not everyone agrees with his opinion. Londoner Brian Wilson started a campaign of his own, handing out 500 badges with the words “Don’t even think about it” on them. “I can’t stand the idea of having to talk to strangers on the Tube on my way to work,” he told the BBC． Michael Robinson, 24, a student from London, agrees. “Being on the Tube is the only place and quietness some people get on their journeys to and from work. Personally, I don’t want to be troubled by people coming up and chatting to you,” he says.
While London does not appear to be social, not everywhere lacks a sense of community. In Melbourne, Australia, commuters have set up a private Facebook group used to warn one another when ticket inspectors (售票员) board the city’s trams (有轨电车). Most Western cities’ tram stops have no barriers, which makes it possible for some travelers to ride them without buying tickets. Though the group comes with a disclaimer (免费申明), its purpose is actually to warn fare paying members that tickets inspectors are on so that they can ready their smiles and most importantly, their tickets.
