I thought this was a clever idea by Liodden because drones are less invasive and less costly and this is a very good way to keep track of the polar bear population which only estimated at about 25,000 for an area that spans millions of square miles. The drones are powered by Intel and have infrared imaging that helps them identify the bear that are camouflaged by snow. 
Liodden's efforts are a great way to keep the polar bears as their population is on the edge of becoming an endangered species ]]> 2017-12-03 21:42:32 UTC https://padlet.com/gabrielvalim/t6i3lt9a91jc/wish/212659050
