问题 单项选择题

某六层住宅工程项目,建筑面积6 500mz,施工人员在拆除顶层模板时,将拆下的10根钢管(每根长3m)和扣件运到物料提升机吊盘上,5名工人一起随吊盘从屋顶高处下降。此时,恰好操作该机械的操作工因上厕所离开岗位,一名刚刚招来两天的木工开动了卷扬机。在物料吊盘下降过程中,钢丝绳突然折断,人随吊盘下落坠地,造成1人死亡4人重伤的恶性后果。

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.
