[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]
