Conservation Drones, Sounds of the Earth’s Magnetosphere
This Week: On the western Indonesian island of Sumatra, scientists are using drones to help protect the endangered Orangutan. The sound of the Earth’s magnetosphere. And a mysterious kidney disease that’s killing thousands of people in Sri Lanka’s rice growing North Central Province. A new study thinks the likely cause is farm chemicals.
The Sounds of the Earth’s Security Blanket: We hear a lot about the fragility of life on earth these days. The impact of 7 billion-plus people is putting huge stresses on the natural systems that we depend on. But at least some of the vital systems that protect our planet are largely beyond our ability to mess with. And that’s a strangely reassuring idea to The World’s environment editor Peter Thomson. He got to thinking about it, when he heard a newly recorded piece of sound.
Conservation Drones Help Protect Orangutans: Primatologist Serge Wich of Liverpool John Moores University has been studying Sumatran orangutans for nearly two decades. The species is critically endangered, threatened by deforestation and poaching. Wich wants to protect the species. So, he monitors orangutan populations. But it takes a long time and costs a lot of money to monitor this tree dwelling species. That’s why he and his colleagues recently decided to put drones to the task. The drones fly over swaths of the forest and come back with detailed pictures. It’s a quick and inexpensive way to track orangutan populations and monitor illegal human activities like logging and poaching.
