Disposing(处理)of waste has been a problem since humans started producing it.As more
and more people choose to live close together in cities,the waste-disposal problem becomes
increasingly difficult.
During the eighteenth century,it was usual for several neighboring towns to get together to select
a faraway spot as a dump site.Residents or trash haulers(垃圾拖运者)would transport household
rubbish,rotted wood,and old possessions to the site.Periodically some of the trash was burned
and the rest was buried.The unpleasant sights and smells caused no problem because nobody
lived close by.
Factories,mills,and other industrial sites also had waste to be disposed of.Those located on rivers
often just dumped the unwanted remains into the water.Others built huge burners with chimneys
to deal with the problem.
Several facts make these choices unacceptable to modern society.The first problem is space
Dumps,which are now called landfills,are most needed in heavily populated areas.Such areas
rarely have empty land suitable for this purpose.Property is either too expensive or too close to
residential neighborhoods.Long-distance trash hauling has been a common practice but once farm
areas are refusing to accept rubbish from elsewhere,cheap land within trucking distance of major city
areas is almost nonexistent.
Awareness of pollution dangers has resulted in more strict rules of waste disposal.Pollution of
rivers,ground water,land and air is a price people can no longer pay to get rid of waste.The amount
of waste,however,continues to grow.
Recycling efforts have become commonplace,and many towns require their people to take part.
Even the most efficient recycling programs,however,can hope to deal with only about 50 percent of a
city"s reusable waste.

In the far north-eastern corner of South Africa, Kruger National Park is the largest
game reserve (野生动植物保护区) in the country, and the most famous wildlife zone
on the African continent. Stretching out over 7,332 square miles, Kruger is a wonderland
of wildlife. It has 507 species of birds and 147 species of mammals. It also has a fair bit
of history it dates back to 1898 when it was founded as a game reserve in an attempt to
control hunting in the area. It didn"t see a tourist until 1927; however, one year later it
became a national park.
It"s a good place to see roaring beasts in their own backyards. South Mrica is an
increasingly hot tourist spot, and you may want to visit it this year, before it hosts the
2010 football World Cup. South Africa is also an inexpensive country for tourists.
Anyone seeking to escape the European winter will be surprised to hear that March
is not the best time to go to Kruger.
The six-month period between May and October tends to be the most suitable time
for wildlife - spotting. The weather is not only cooler but also considerably drier. This
means that water sources dry up and animals are forced to approach rivers, creeks, dams
and watering holes in search of liquid refreshment.
If you go to South Africa, you need to pay attention to the threat of malaria (疟疾).
Kruger is one of the only two South African national parks that have an issue about the
disease, but only during the rainy season ( December to April).
A disadvantage of Kruger is that it sits a long way from South Africa"s other well-known
tourist attractions Cape Town, the Garden Route, and the meeting of the Atlantic and Indian
Oceans at Cape Agulhas.

In one of the strongest indications of the power of the mind to influence the body, a growing collection of evidence finds that people who are depressed have a greatly higher risk of developing heart disease. In a study of almost 3,000 men and 5,000 women, depressed men were 70 per cent more likely to develop coronary (心脏的) heart disease than those who weren"t depressed. While depressed women were just 12 per cent more likely to develop heart disease, those who were severely depressed were 78 per cent more likely. In fact, a 1998 study found that women who are depressed have a risk of dying from heart disease equal to that of women who smoke or who have high blood pressure. The link works the other way around, too: While about 1 in 20 American adults experience major depression in a given year, that number jumps to about one in three among those who have survived a heart attack. The more severe the depression, the more dangerous it is to your health. But some studies suggest that even mild depression, including feelings of hopelessness experienced over many years, may damage the heart. Other studies suggest depression may affect how well heart disease medications work. Researchers aren"t sure what the connection between depression and heart disease is, but theories exist. One is that people who are depressed tend not to take very good care of themselves. They"re more likely to eat high-fat, high-calorie "comfort" foods, less likely to exercise, and more likely to smoke. But beyond lifestyle, there is probably also a physiological link between depression and heart disease. Recent studies found that people with severe, depression tended to have a lack of heart-healthy 0-3 fatty acids. People who are depressed also often have high levels of stress hormones (荷尔蒙). These keep the body primed for fight or flight, raising blood pressure and causing the heart to beat faster, all of which put additional stress on coronary arteries (动脉) and prevent the body"s natural healing mechanisms from working properly. A whole branch of medicine is devoted to the complex links between mental health, the nervous system, the hormone system and so on. This science is gradually sorting out how the mind-body connection affects us, or defenses against heart disease. Generally, an estimated 10 per cent of American adults experience some form of depression every year. Although available treatments can ease symptoms (症状) in more than 80 per cent of people treated, less than half of those with depression get the help they need. | |
