From The Times:
If wild bears, boars or monkeys are getting a little too close for comfort, who you gonna call? If you’re in Japan, you can now enlist high-tech pest deterrents such as the “Monster Wolf”, or flying drones that bark.
Pests cause $120 million in crop damage annually in Japan, with deer and boar responsible for 60 per cent. Their populations are believed to be about 2.6 million and 800,000 respectively, according to the Japanese Ministry of the Environment.
