3 . REDUCING WATER POLLUTION IN THE LI RIVER

The beautiful Li River and its amazing surrounding scenery is one of the most well-known tourist destinations in China’s Guangxi Zhuang Autonomous Region. It attracts millions of domestic and foreign visitors each year. However, its reputation as a top destination has had negative effects on the river’s water quality. This report looks at the problem of water pollution and some actions that have been taken to deal with it.

Previously, water quality in the Li River had suffered greatly from an increasing volumeof tourists, many of whom frequently threw garbage into the river. Many tour boats contributed to the problem too. Kitchens on board were using lots of oil, which was often thrown into the water. The growth in tourism also meant the local population rose rapidly, as well as the number of commercial and industrial enterprises. Water pollution levels increased, with more household and commercial waste ending up in the river. In order to feed more people, more chemicals were used to increase crop production. These chemicals led to severe water quality issues, causing a decrease in the number of fish species. Local officials were concerned that the pollution was damaging the natural environment and felt that urgent steps should be taken to restore the river’s original beauty.

A comprehensive initiative was started, with a number of measures that addressed the issues. The construction of waste water treatment facilities improved the water quality and water conservation. The collection and transport of household waste was also improved. Dozens of polluting enterprises were closed or moved. The local government set up strict regulations regarding further industrial development. New rules were also introduced regarding tour boat routes and garbage disposal methods. Furthermore, the local authorities began to use the media to spread environmental awareness and encourage greater use of clean energy. At the same time, they started to carry out inspections regularly and fine tourist organisations for abuses. With these measures, it is believed that the beauty of the Li River will be preserved for generations to come.

In addition, the ambitious “Water Ten Plan” is also now tackling water pollution across the country. Other initiatives, such as the “River Chief System”, hold senior officials responsible for reducing water pollution. With such campaigns in effect, China’s waterways are heading towards a clean and sustainable future.

People may find it unbelievable that two hundred years ago people did not link illness     1     environmental problems. In London, drinking polluted water led     2     many deaths from cholera. It always started in the poor neighborhood, and then it spread to the richer areas as the servants infected     3     the illness passed it on. Many doctors suspected    4    polluted water was     5     (blame). John Snow’s     6     (finding) proved that the dirtier the water, the     7     (severe) the illness. Therefore, they concluded that water must be     8     (pure). They instructed the     9     (handle) be removed from pumps if the water carried the virus. Thanks     10    John Snow, cholera was defeated eventually.

9 . As cultural symbols go, the American car is quite young. The Model T Ford was built at the Piquette Plant in Michigan a century ago, with the first rolling off the assembly line (装配线) on September 27, 1908. Only eleven cars were produced the next month. But eventually Henry Ford would build fifteen million of them.

Modern America was born on the road, behind a wheel. The car shaped some of the most lasting aspects of American culture: the roadside diner, the billboard, the motel, even the hamburger. For most of the last century, the car represented what it meant to be American—going forward at high speed to find new worlds. The road novel, the road movie, these are the most typical American ideas, born of abundant petrol, cheap cars and a never-ending interstate highway system, the largest public works project in history.

In 1928 Herbert Hoover imagined an America with “a chicken in every pot and a car in every garage.” Since then, this society has moved onward, never looking back, as the car transformed America from a farm-based society into an industrial

The cars that drove the American Dream have helped to create a global ecological disaster. In America the demand for oil has grown by 22 percent since 1990.

The problems of excessive (过度的) energy consumption, climate change and population growth have been described in a book by the American writer Thomas L. Friedman. He fears the worst, but hopes for the best.

Friedman points out that the green economy (经济) is a chance to keep American strength. “The ability to design, build and export green technologies for producing clean water, clean air and healthy and abundant food is going to be the currency of power in the new century.”

What has the use of cars in America led to?

The findings raise the possibility that reducing pollution may lead to a drop in diabetes cases in heavily polluted countries such as India and less polluted ones such as the United States.

Diabetes is one of the fastest growing diseases, affecting more than 500 million people worldwide. The main drivers of diabetes include eating an unhealthy diet, having a sedentary lifestyle and obesity, but the new research indicates the extent to which outdoor air pollution plays a role.

“Our research shows a significant link between air pollution and diabetes globally,” said Ziyad Al-Aly, MD, the study’s senior author and an assistant professor of medicine at the University of Washington. “We found an increased risk, even at low levels of air pollution currently considered safe by the US Environmental Protection Agency (EPA) and the World Health Organization (WHO). This is important because many industry lobbying (游说) groups argue that current levels are too stringent and should be relaxed. Evidence shows that current levels are still not sufficiently safe and need to be tightened.”

While growing evidence has suggested a link between air pollution and diabetes, researchers have not attempted to quantify that burden until now. “Over the past two decades, there have been bits of research about diabetes and pollution,” said Al-Aly. “We wanted to thread together the pieces for a broader, more solid understanding.”

The researchers also found that the overall risk of pollution-related diabetes tilted (倾斜) more toward lower-income countries such as India that lack the resources for environmental mitigation systems and clean-air policies. For instance, poverty-stricken countries facing a higher diabetes-pollution risk include Afghanistan, Papua New Guinea and Guyana, while richer countries such as France, Finland and Iceland experience a lower risk. The US experiences a medium risk of pollution-related diabetes.
