One good tern deserves another

Arctic terns, birds long famous for their thousands of miles migratory habits, have been profoundly affected by climate change. Researchers have determined that as landmarks have disappeared due to loss of ice, some terns get stressed to the point of prematurely ending their flights. Exposure to cannabinoids reduces stress levels in the stopped birds, allowing them to continue their journey. A team formed to find the colonies of stragglers and drop literal marijuana smoke bombs on the birds. The head of the expedition acknowledged that it was a huge undertaking, but vowed to leave no tern unstoned.
