Fraser Davidson gobbles a plane at The Hangar at Manchester Airport on June 26, 2024. An airport pub serves drinks just 15 metres from the runway–- and drinkers can watch planes coming into land over a pint. The Hangar, Manchester, is 50 feet away from the airport, and people don't need to be checked in to drink there. It boasts a “unique perspective” for customers, who can enjoy a pint right next to planes taking off and landing. (Photo by South West News Service)

Among the fish populations that could be harmed by the Xayaburi dam in Laos is the critically endangered Mekong giant catfish, considered by the Guinness Book of World Records to be the world’s largest freshwater fish. The fish, which grows to 650 pounds and about 10 feet long, is only found in the Mekong River. It is migratory, moving between downstream habitats in Cambodia upstream to northern Thailand and Laos each year to spawn. Some experts fear the Xayaburi dam could block the migration and drive the giant catfish to extinction. (Photo by Courtesy of Zeb Hogan/University of Nevada, Reno)
