Passage Two

Questions 51 to 55 are based on the following passage.

Degradation of the world's natural resources by humans is rapidly outpacing the planet's ability to

absorb the damage, a recent UN environmental study has found. The study concludes that without radical

action the level of prosperity that millions of people in the developed world count on will be impossible to

maintain or extend to poorer countries.

Water scarcity is the curse of some of the poorest regions on Earth, leaving developing countries

increasingly unable to feed themselves, and causing hardship for millions of people. There appears little

prospect of this desperate situation being remedied without radical action being taken. Water resources are

under increasing threat from population growth, climate change, rapid urbanization, rising levels of

consumption, and the degradation of lands that previously provided a natural replenishment (补充） of

water resources.

The rate of damage to the natural environment was found to increase globally, despite concerted

efforts to persuade governments to take measures to improve the condition. "If current trends continue,

and the world fails to improve patterns of production and consumption, then the state of the world's

environment will continue to decline," warned UN executive director Achim Steiner.

He said the tools for improving the environment for millions of people existed in developed countries,

but were in danger of not being used.

The study found that basic measures to tackle some of the key causes of environmental damage were

still not being taken. These included measures to reduce air pollution, to control the damage to marine

eco-systems, which can have a huge effect on fish stocks on which hundreds of millions of people depend;

and to curb the degradation of land where modern agricultural methods were pursued without regard to the

longer-term consequences.

Despite the recent global agreement on cutting greenhouse gas emissions, global carbon output

continues to rise. This will put a long-term strain on the ability of developing economics to feed their own

people. Climate change is aggrav.ated by the emissions of greenhouse gases from chemical and natural

fertilisers used in agriculture which increased by more than a quarter between 2000 and 2010. Other

problem areas identified in the report included glaciers, which provide vital water resources for millions of

people, but which are shrinking as the climate warms.

In rich countries, these problems have built up over decades and centuries while economic growth was

pursued at the expense of the environment. Subsequent efforts to remedy the environment have met with

partial success. But in developing countries, the path of future development has more potential to change,

which has encouraged international institutions to devise more sustainable growth pathways that are

supposed both to alleviate poverty and preserve the environment.
