00:00 Before watching the video, I remind you that there is more content on the Hotpot website.

00:04 Hai Li is fat, short and flat-tailed.

00:08 His cute appearance is a magic of fans.

00:10 But don't underestimate Hai Li's little will.

00:13 They are actually experts in building water dams.

00:15 They even have the reputation of nature engineers.

00:18 Hai Li will collect wood and dig a waterway to build a water dam.

00:22 In addition to effectively irrigating the land,

00:24 turning the dry land into a green wetland,

00:27 it can also slow down the flow of water and control flooding.

00:30 It can be said to be a great achievement in rebuilding the ecosystem.

00:34 In fact, 400 years ago,

00:36 British Hai Li was infected by human over-killing.

00:39 Until 2005, a farm owner brought back three pairs of Hai Li from Germany for cultivation.

00:45 Hai Li reappeared in the UK

00:48 and became a native species protected by British law.

00:52 In recent years, the UK has also started to put Hai Li in the wild

00:55 in the hope of helping them rebuild the local ecosystem with their talents.

01:00 Let's go to London, UK to see their cute figure.

01:03 Hai Li's family walks out of the cage and slides into the water to start a new life.

01:10 The small lake in the London city center has recently welcomed five new members

01:14 and attracted a large number of people to the site to join in the fun.

01:16 The founder of the British Wildlife Organization said

01:19 that putting Hai Li as a nature engineer into the ecosystem

01:23 will help reduce the local water disaster risk.

01:25 They are able to transform the landscape and they provide ecosystem services.

01:29 For example, they will help this landscape hold more water

01:32 and that will slow the flow and reduce flood risk locally.

01:36 After 400 years, Hai Li is once again seen in the lakes of London, UK.

01:41 The British Wildlife Organization said

01:43 that they hope the government will actively push for Hai Li to return to nature

01:47 and use Hai Li's power to improve the nature of the country.
