The culture of veneration and protection extends right across Tibet |
[00:06.89] |
helping to preserve a unique yet fragile ecosystem |
[00:17.62] |
Out on the plateau there's a small creature that's at the root of much of the grasslands' delicate ecology |
[00:25.46] |
Despite summer snow storms, the pika, a relative of rabbits and hares |
[00:30.47] |
is perpetually eating and gathering grass |
[00:33.60] |
and digging burrows for its family |
[00:39.99] |

[01:40.59] |
the fox and the bear |
