United Nations warn animals important to agriculture are dying out forever. The UN Environment Program
and Food and Agriculture Organization showed us a report. The findings are based on the information collected
in 170 nations during the past ten years.
FAO officials say the world has lost about one thousand kinds of farm animals in the past one hundred years, and that 1/3 of them are at risk of disappearing. FAO officials are concerned about farmers producing enough to feed the world' s population. FAO has got the information about over 4,000 kinds of birds and animals
population. 740 of those breeds no longer exist. 1,300 others are said to be endangered or at high risk of
extinction.
Many of them are important than animals. For example, in Madagascar, Renitelo cattle have almost
disappeared. In the Philippines, the Banaba chicken is now rare. Fewer than 1,000 of the birds remain. In
Mexico, the Chiapas sheep are at the export (出口 ) of animals from industrial to developing countries. The
report says animals from industrial nations are often considered more productive in developing countries.
However, the animals are best for the environment of areas they are from. Now the UN is starting a five-year
project to help countries better understand the issue.
