[00:00.86]Another endangered species 1,
[00:02.83]the Yangtze Dolphin,is China's only fresh-water
[00:06.53]dolphin and is sometimes called' the panda
[00:09.35]of the Yangtze River'because it is so rare.
[00:13.11]its numbers are decreasing for several resons
[00:15.96]including the pollution of the river
[00:18.11]and the fact that they are often caught
[00:20.11]and killed in fishermen's nets.
[00:22.51]Hunting in the past also played a role
[00:24.97]in rapidly reducing numbers.
[00:27.51]Education programmes have been set up
[00:30.26]but much more needs to be done
[00:32.20]to protect these animals.
[00:34.71]The tiger is a species under severe threat.
[00:37.94]In the 1950's,
[00:39.43]there were eight sub-species of tiger,
[00:42.25]but three are now extinct 2.
[00:44.71]All five remaining species are endangered
[00:47.54]and although they are protected,
[00:49.38]the total number of tigers worldwide
[00:51.95]has dropped to 5,000.
[00:53.76]Why is this?Tigers are killed by hunters
[00:57.40]because it is falsely believed
[00:59.09]that parts of the tiger's body
[01:00.78]are good for people's health.
[01:02.91]Another reason for numbers have decreased
[01:05.10]is the loss of the tiger's natural habitat.
[01:08.06]To save these beautiful animals,
[01:09.97]we need to stop illegal hunting
[01:12.29]and extend 3 conservation programmes.
[01:12.29]
