As hundreds of polar bears gather near Churchill in Canada, conservationists are testing noisy drones to move them away from populated areas. They are also developing AI-powered cameras to detect approaching bears and installing electric fencing at a waste facility. The measures aim to protect people and animals as climate change delays sea ice formation, increasing the risk of encounters.
