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.

When you enter a crowded room or go on a picnic or to a party, who is the most attractive and appealing person? It is the person who is cheerful, has a smiling face and behaves as if he or she is enjoying every moment of the event! Such people have an optimistic opinion on life. They are the ones with a positive attitude. On the other hand, let’s see that fellow in the corner with a long face. He is most probably thinking about the time and money wasted in having fun. He is a pessimist, one with a negative attitude.

A person with a positive attitude gets on well with the job at hand. He doesn’t worry about what’s gone before or what might happen in the future. If there is a problem, he quickly thinks of ways to solve it. If the problem cannot be solved singly, he seeks help from someone else. He doesn’t feel that it’s beneath his dignity to seek assistance.

When Sonal lost her history notes days before an important examination, she sat down and cried. Then she pulled herself together, borrowed a friend’s notes, worked day and night and managed to copy down whatever she had lost. Sonal passed the exam with flying colors.

It’s just not possible, even for the greatest optimist, to smile all the time and feel good all day. Everyone has a period of blues now and then, when everything seems sad and without cheer. But once you develop a positive attitude, once you realize that life is a series of ups and downs, dark clouds and bright sunshine, in no time at all, you’ve bounced back, ready to welcome the world again with open arms and a huge smile! So from this moment on, keep your face to the sunshine and you’ll never see the shadows.
