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 bee 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 bee 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 munities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.

(答案→)C
解析：本文主要讲述的是全球气候的变化对野生动物的影响，文章中举了很多具体的例子来进行详细地说明。也提出了该如何来解决这些问题的具体的建议。
【小题1】C 段落大意题。根据本段2,3，4行how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa.可知本段是讲述的是导致生态破坏的具体的原因。故C项正确。
【小题2】D 细节题。根据文章第四段The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats.可知在mountains, isolated islands and coastal areas，动物迁徙的机会很少，故D正确。
【小题3】B 细节题。根据文章最后3段The FAO also called for the creation of migration corridors for animals in areas where their movement was limited.和The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed.以及 It also urged local munities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.说明ACD三段都是文章中提及的方法和途径，只有B项文章没有涉及。
【小题4】C 推理题。根据It also urged local munities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.可知这个组织敦促当地国家发展一些计划来减少气候变化对野生动物的影响。故该词是指C项内容。
【小题5】A 主旨大意题。本文主要讲述的是全球气候的变化对野生动物的影响，文章中举了很多具体的例子来进行详细地说明。也提出了该如何来解决这些问题的具体的建议。故A正确。
