Animal conservation

Many animal and plant species have become extinct and many more are in critical danger.Finding ways to protect the earth's wildlife and conserve the natural world they inhabit(居住)is now more important than ever.

Dodos

The Dodo is a classic example of how human caused damage to the earth's biology.The flightless Dodo was native to the Island of Mauritius in the Indian Ocean.It　 lived off fruit fallen from the island's trees and lived unthreatened until humans arrived in 1505.The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the Island by humans such as pigs, monkeys and rats.The population of Dodos rapidly decreased and the last one was killed in 1681.

Rhinos

The Rhino(犀牛)horn is a highly prized item for Asian medicine.This has led to the animal being hunted in its natural habitat.Once widespread in Africa and Eurasia，most Rhinos now live　 in protected natural parks and reserves(保护区)．Their numbers have rapidly decreased in the last 50 years，and the animals remain under constant threat from poachers(偷袭者)．

The Giant Panda

The future of the World Wildlife Fund's symbol is far from certain.As few as 1，600 pandas remain in the wild.The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison.However，the panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose(造成)one of the most serious threats to the animal's continued existence.

Whales

The International Whaling Commission is fighting to ensure the survival of the whale species.Despite the fact that one－third of the world's oceans have been declared the whale sanctuaries(保护区).7 out of 13 whale species remain endangered.Hunted for their rich supply of oil，their numbers have decreased to just 300.Collisions with ships，poisonous pollution and being caught in fishing nets are other major causes of whale deaths.

Tigers

The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5，000 and 7，000 and The Bali，Javan，and Caspian tigers are already extinct.The South China tiger is precariously close to disappearing，with only 20 to 30 still alive.Like the Rhino horn，tigers' bones and organs are sought after for traditional Chinese medicines.These items are traded illegally along with tiger skins.

Several animal species including gorillas in Rwanda and tigers in Bangladesh could risk extinction if the impact of climate change and extreme weather on their habitats is not addressed, a UN report showed on Sunday.

Launched on the sidelines of global climate negotiations in Durban, the report by the United Nations Food and Agriculture Organization shows how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa.

“Many ecosystems have already been stressed by increasing population, historical and recent deforestation, unsustainable management practices and even invasive (入侵的) species,” Eduardo Rojas-Briales, assistant director general at the FAO's forestry department, said at the launch of the report.

The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats.

“The remaining populations become surrounded in very small ecosystems, they have inbreeding (近亲交配) problems ... and at the end these species may disappear,” he added.

Other examples of affected animals included elephants in Mali, lions in the Serengeti and crocodiles in Malawi.

The report said an estimated 20-30 percent of plant and animal species will be at higher risk of extinction due to global warming and a significant proportion of native species may become extinct by 2050 as a consequence.

Other consequences could include the spread of invasive species and infectious diseases, it said.

The report urges more focus on restoration of damaged ecosystems, especially those key to dealing with climate change such as mangroves(红树林), inland waters, forests, savannahs(非洲大草原) and grasslands.

The FAO also called for the creation of migration corridors for animals in areas where their movement was limited.

The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed.

It also urged local communities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.

1.What does the author tell us in Paragraph 2?

A．The theme of global climate negotiations in Durban.

B．The subject of research done by Eduardo Rojas.

C．Causes of damage done to ecosystems.

D．Harmful effects of damage done to ecosystems.

2.Why are animals living in mountains, islands and coastal areas most affected?

A．They are frequently attacked by invasive species and infectious diseases.

B．They have difficulty finding enough food for survival.

C．They can hardly find mates to produce their young.

D．They have little chance of moving to other places.

3.To avoid extinction of some animal species, the UNFAO suggested all the following ways EXCEPT ______.

A．restoring damaged ecosystems

B．limiting world population growth

C．creating movement channels for animals

D．urging governments and local communities to take action

4.What does the underlined word “mitigate” in the last paragraph mean?

A．increase or further improve something.

B．Make full use of something.

C．Make something become less serious.

D．Move from one place to another.

5.What would serve as the best title for the passage?

Living in a modern society with more and more out-of-date but still useful computers, many people have to face such a troubling problem: How to deal with those old computers? Some old ones are put away in homes. Many more are just thrown out with the rubbish.

Don’t worry! Some companies are coming up with new ways to cut the number of old computers. Sony, Dell, Hewlett-Packard and other companies now agree to take back some old computers.

In some countries, there are laws about what to do with old computers. By law, computer companies will have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade（升级）.

While many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations（组织）are working to solve this problem. They collect and repair old computers before sending them to schools, charities（慈善团体）and people who need them.
