World's Greatest Swimming Pools: Four Seasons, Serengeti Pool, Tanzania. A show of elephants, buffalo and baboons awaits thanks to an active watering hole below the free-form infinity pool at this plush hideaway inside Serengeti National Park. Bonus: Because of infrared technology at the hole, guests can be notified on their bedroom TV when animals are approaching. When you've got word of wildlife on the horizon, catch them from your private terrace – or head back to the pool. (From $1,650). (Photo by Four Seasons)

In this photo taken on Monday, October 27, 2014, a cactus stands at a broken window in a damaged house after shelling not far from Donetsk airport in the town of Donetsk, eastern Ukraine. Donetsk, which has lost about 400,000 of its 1 million pre-war population, is bracing to a winter ahead. In a climate like eastern Ukraine's, where temperatures typically stay below zero all winter, the damage to the critical infrastructure and lack of effort to provide adequate shelter to people whose homes were destroyed could literally mean a death from the cold.
