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 (毁灭) 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 (光合作用) by green plants. Insects, worms and bacteria 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 (不可挽回的).”
But what can we do? The present problem is that the concept of biodiversity is so vague (含糊的). 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 Biodiversity 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 (wild dogs) 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!

Fukushima (Japan) last year the issue is back in the headlines. And the world is divided- some countries
are planning more nuclear plants, while others have promised to shut theirs down.
After Fukushima, Germany decided to switch off all its nuclear plants by 2022. Switzerland and Italy
are also phasing out nuclear power. But France and the United States remain staunch supporters of
atomic energy. In fact, almost 80% of France's electricity comes from nuclear power, the highest
percentage in the world. And in the US, the Obama administration said it "continues to support the
expansion of nuclear power, despite the crisis in Japan."
Nuclear supporters claim nuclear power can help the environment. Unlike fossil fuels, nuclear power
doesn't create greenhouse gases. So, pro-nuclear countries argue that nuclear power allows them to
generate energy without contributing to climate change. Britain's chief scientific adviser (John Beddington)
supports this view. He recently said that the world doesn't have the luxury of ignoring nuclear energy.
Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind power
may be clean, but they're expensive; and right now, they require a lot of investment. This higher cost of
using "green energy" is usually passed onto the consumer. So, while many people may prefer their energy
to come from a renewable source, not so many are prepared to pay higher energy bills. This is of
particular concern while the world economy is in such bad shape.
The main argument against nuclear energy is that it isn't safe. For a start, nuclear waste is very difficult
to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there
were several high-profile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in
the Ukraine. The radiation from the meltdown spread all over Europe, affecting thousands.
The nuclear energy issue is very complex. And it doesn't look like it'll be resolved anytime soon. As a
Japanese commentator recently said, "it's been a bad year for the 'nuclear village', but I don't think they're down and out yet." The battle continues.
B. Nuclear energy can help prevent the climate damage.
C. Nuclear energy is more environmental-friendly than other green energy sources.
D. Nuclear energy can save the consumers some money, compared to other renewable energies.
higher bill.
B. The cost of using renewable sources
C. The fact that the nuclear power is cheaper.
D. The investment of renewable energy sources
B. explain that nuclear waste may remain harmful to humans for thousands of years.
C. persuade the world not to use nuclear energy.
D. support the idea that nuclear energy is not safe.
B. the nuclear energy issue will be soon settled.
C. a battle will break out in the future.
D. Japan is considering to build a nuclear village in the future.
B. To introduce some serious nuclear disasters.
C. To show the argument between nuclear supporters and protesters.
D. To give some advice on how to use nuclear energy safely.
Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost unavoidably associated with environmental damage.
Economic growth is the increase in numbers of goods and services produced over time by an economy, and it is calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation (通货膨胀)is adjusted in order to take into account its misleading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total demand.
There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long term health effects to nearby populations of animals, or people. They also lead to global warming.
Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.
In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would block airflows’ natural speed which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pressure balance that is brought about by this current will be affected, and it is important to remember that the environment and weather conditions are directly affected by atmospheric pressure.
For these reasons, bringing about economic growth without any resulting environmental damage, whatsoever, is impossible.
