12、 English abbreviation(缩写) for the World Wide Fund for Nature. WWF was founded in 1961 and was originally called World Wildlife Fund with its headquarters（总部） in Switzerland. It aims to urge the parties concerned to attach more importance to（认为.很重要） the threats the natural environment is faced with t

13、hrough efforts such as organizing, publicizing（宣传） and educating. It strives to win spiritual and material support（精神和物质的支持） worldwide, to put this support into practice on a scientific basis, and to provide funds and techniques for wildlife protection projects worldwide. Chinas many projects such a

14、s pandas, white-fin dolphin, wapiti (麋鹿), etc, have received help from WWF. The WWFs work scope（工作范围） aims to protect the natural environment and ecology on earth. Protection of Wildlife and Endangered Species. Q:What is the main task of the WWF?B While Wisconsin is blessed with many natural areas,

15、our wildlife still face several threats over the long term. We need to support programs which will protect wildlife and endangered species, or risk losing some of them. Key Threats to Wildlife 1. Habitat Loss - Because our population is growing and our cities are sprawling into the countryside, fewe

16、r natural wildlife habitat areas are left each year. And the habitat that remains has often been degraded to bear little resemblance to the natural wild areas which existed in the past. In many areas, only islands of habitat remain, isolated in the middle of large agricultural or urban developments

17、- preventing normal interactions, healthy breeding or safe travel for many species. Some wildlife species, such as deer, rabbits and chipmunks, are adaptable to many conditions, but other creatures have very specific plant, moisture and temperature requirements. These are the endangered species whic

18、h we risk losing if we dont preserve adequate amounts of habitat for their survival.2. Climate Change - Because many types of plants and animals have specific habitat requirements, climate change could cause disastrous losses of wildlife species from Wisconsin. A one or two degree change in average

19、annual temperature will translate into large changes in Wisconsin, affecting snow cover in the winter and excess heat in the summer. Many northern Wisconsin plants and animals depend on a blanket of snow to insulate them from extreme low temperatures of winter. It may be 25 degrees below zero in the

20、 open air, but barely freezing (32 degrees) beneath the snow. Without this insulation, many plant species (even trees) will decline or disappear entirely. Hibernating mammals, reptiles, amphibians and insects will be harmed also. Similarly, higher temperatures would increase evaporation year round,

21、and may reduce rainfall, leading to drier than normal conditions across the state. Plants and wildlife are sensitive to moisture changes, so they will be harmed by this dryness. Coldwater trout streams may become too warm to support trout, or may dry up. Unfortunately, trees and plants cant simply p

22、ick up and move to a more hospitable location. Instead, they will die where they stand, exposing and starving the wildlife that depend on them. Drought tolerant plants and trees will gradually spread to replace them by seed, but this process takes time. In many parts of Wisconsin, natural habitat is

23、 chopped up and isolated in small islands. This means plants and animals have no bridge to allow them to move with the changing climate. (see Climate Change in Wisconsin) 3. Pesticides and Toxic Chemicals - Pesticides are deliberately spread to make the environment toxic to certain plants, insects o

24、r rodents, so it shouldnt be surprising that other plants and wildlife are often harmed at the same time. While many of the worst pesticides have been outlawed in the past 30 years, scientists have found numerous worries with several pesticides which are still legal and commonly used. In addition, m

25、any chemical pollutants are toxic to wildlife, such as PCBs, mercury, petroleum byproducts, solvents, anti-freeze, etc. 4. Non-native Species - Over the past 150 years, many non-native plants, mollusks, insects, fish, birds, mammals, and diseases have found their way to Wisconsin. These include such

26、 well-known headaches as buckthorn, carp, zebra mussels, spiny water fleas, purple loosestrife, gypsy moths, Eurasian milfoil, feral cats, white perch, West Nile Virus, Japanese beetles, and starlings. These aliens are often aggressive competitors with native wildlife, or predatory, especially after

27、 theyve left their own natural environments and controls. 5. Mismanagement - Some native wildlife can become a problem when released from their natural population controls. When wolves are scarce and hunters too few, white-tailed deer will often strip the woods of native wildflowers (such as Trilliu

28、ms) and even certain tree species (such as Hemlock), when their populations are allowed to become too high. Canada geese are beautiful birds, but when city folk feed native geese as if they were pets, their populations can rise to uncomfortable levels in urban areas, resulting in polluted waterways

29、and manure-laden lawns. Gulls can become similar problems, when they scavenge for scraps from our garbage heaps and landfills. Q:What are the key threats to the wildlife?C Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant

30、faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. Thats why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with e

31、lephants in Africa.Years ago, overhunting and the ivory trade were the biggest threats to elephants survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.The 21st century brings a different challenge to elephant conservation land-use. Elepha

32、nts walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information
