     Several animal species including gorillas (大猩猩) the in Rwanda and tigers in Bangladesh could risk

extinction if impact of climate change and extreme weather on their homes is not handled, a UN report

showed on Sunday.

     Released during the course of global climate negotiations in Durban, the report by the United Nations

Food and Agriculture Organisation (UNFAO) shows how higher temperatures, the rise in sea levels,

deforestation and overuse of land have damaged the habitats of certain species, especially in Africa.

"Many ecosystems have already been affected by increasing population, historical and recent

deforestation, short-lasting management practices and even invasive species," Eduardo Rojas, assistant

director general at the UNFAO's forestry department, said at the release of the report.

     The most affected areas include mountains, islands and coastal areas, which limit the possibilities for

animals to move elsewhere and create new habitats. "The remaining populations are limited to very small

ecosystems. They have inbreeding (近亲繁殖) problems.., and at the end these species may disappear,"

he added.

     Other examples of affected animals include elephants in Mall, lions in Serengeti and crocodiles in

Malawi. The report says about 20~30 percent of plant and animal species will be at higher risk of

extinction due to global warming and a significant number of local species may disappear 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 inland waters, forests and grasslands. The UNFAO also called for the

creation of movement channels for animals in areas where their movement was affected. The organization

said while more resources (资源) were flowing to biodiversity conservation, more action at th

government and policy level was needed. It also urges local communities to develop projects that ease

the effect of climate change on wildlife, naming ecotourism activities as an example.
