Lowry Park Zoo elephants Matjeka, 23, and her 1-year-old daughter, Mavi, apply a liberal coating of “sunscreen” to themselves in a clay mud wallow at the park Tuesday, August 12, 2014, in Tampa, Fla., on the park's first observation of World Elephant Day to raise awareness of the wild African elephant crisis. “Elephants are prone to being sunburned”, said associate curator Chris Massaro. “What they need is lot of mud or clay to roll around in and cover up their skin so it will protect it from the sun”.

In a simpler time all a child or an adult needed to enjoy the outdoors was a ball and a stick. Or maybe an old tire tied to a high branch to fashion a swing. And the only instruction given to children was to “be home before dark”. Now there are iPads and computers and television screens and shrinking safe public spaces. But despite the distractions and limitations of space, these images show the charm of kicking a ball or skipping rope endures. Sometimes with modifications as a nod to changing times.

Tens of thousands of vehicles damaged by super storm Sandy are being temporarily stored on runways and taxiways at Calverton Executive Airpark in Calverton, New York, on January 9, 2013 in this aerial view. Insurance Auto Auctions Inc, a salvage auto auction company specializing in total-loss vehicles, acquired the cars and trucks that were damaged, destroyed or flooded by the storm and needed a place to store them. The company made a deal with the Town of Riverhead to lease the airport land and then the vehicles are auctioned online. (Photo by Stan Honda/AFP Photo)

Just a week before Rio de Janeiro hosts South America's first Olympics, city residents expressed mixed feelings about the cost and security of the Games, while holding out hope they will bring joy to a nation facing economic and political crises. The conflicted thoughts mirror a recent survey by the Datafolha polling group showing that half of Brazilians were opposed to holding the Games, while 63 percent think the costs of hosting the event will outweigh benefits.

A sign advising to pray for rain hangs above an exhibit area at the 47th Annual World Ag Expo in Tulare, February 12, 2014. About a hundred years ago, when urban water systems were being developed throughout the state, the city of Sacramento wrote protections from metering into its charter, vowing that residents would always have the right to use as much water as they needed. But on Tuesday, the state's top water regulators released a framework for enforcing California's first statewide mandatory restrictions on urban water use – cuts of 25 percent for non-agricultural users ordered last week by Democratic Governor Jerry Brown as a devastating drought enters its fourth year.

Pictures from Tasmania’s central plateau, shot by wilderness photographer Dan Broun, show the extraordinary damage wrought by more than a week of bushfires following lightning strikes in Australia’s southernmost state on January 13. 2016. The world heritage area was home to a range of unique alpine flora including pencil pines, king billy pines and cushion plants, some more than 1,000 years old. Now more than 10,000ha of land has been incinerated, and ecologist say that, unlike eucalyptus trees, the ancient flora will not recover. (Photo by Dan Broun)
