A pink cloud brings a pretty image to mind, but perhaps not if you’re in certain parts of India these days. Millions of locusts have been descending on farms and gardens in India, unlike any other previous attacks.
A short grasshopper-like insect, locusts are usually solitary and typically harmless—that is, unless they transform into enormous insect clouds, moving randomly across the landscape, causing damage to crops and plants. India and its neighbor Pakistan, often bitter enemies, recently came together to share pesticides and best tactics to get rid of the locusts. The new remedies now include drones, which can spray ten liters of pesticide at a time and make specific-pitched sounds that disperse the locust swarms. The good news is that these drones might be able to reach places that people on foot or tractors are unable to, making the job easier for farmers and landowners.
What’s the most exciting use of a drone you’ve seen?
