VOA常速英语:带有红外摄像头的无人机可以帮助追踪考拉

Douglas Thron, a cinema photographer from California, is using drones equipped with infrared cameras, to help track koalas in the wild in the Australian State of New South Wales. You fly the drone over an area and you do it while the ground is cooler, and then the heat of the animal pops up and you can see the shape of the koala basically. Thron had previously used his device to locate and rescue animals after Hurricane Dorian struck the Bahamas, while there he learned of devastating bushfires in Australia. I saw these videos of basically, you know, koalas have been burned up and people are trying to rescue koalas. The Australian bushfires in 2019 and 2020 killed all displaced nearly three billion animals, including koalas, kangaroos and other native species, according to a study released last week by the World Wide Fund for Nature.
WWF called it one of the worse wildfire disasters in modern history. Now with the ability to track koalas using drones, Stuart Blanch of WWF marvels at what he calls a breakthrough. Drones are sort of a next level way of quickly finding koalas across hectares of bush. Volunteers also are tracking koalas. Sue Gay and her daughter regularly look for animals around their home in a town near Sydney. What method is to look for fresh Koala feces? Others attempt to look up into the trace for them, I tend to look down. And I can tell mobile that say that tell for and then. Then you've got the scratch much from the traces well. Well, tracking koalas this way is slow. They say the effort to save them is worth it. let's getting to action and save these guys. The New South Wales Threatened Species Advisory Board and Independent Committee of Scientists had started to review to determine whether the koalas' status should be upgraded to endangered. The World Wildlife Fund warns that without an urgent government intervention, koalas in eastern Australia could be extinct by 2050.
