Ja Kang Song, 71, and Ja Hyun Su, 72, dive for shellfish and are the main breadwinners for their families. In South Korea, 45% of the diving women of Jeju are over the age of 70. Routinely diving to depths of 20m and staying under for an average of two to three minutes, the pressure on the body takes its toll and, like many others, burst eardrums have left Ja Hyun Su deaf. Each season, between seven and 10 women die diving the waters around Jeju Island. (Photo by Andy W. Langton/Age International)

A visitor kneels on the 180-meter-high and 300 meter-long glass-bottomed suspension bridge at the Shiniuzhai National Geopark in Pingjiang county, in central China's Hunan province, 24 September 2015. Tourists visited a glass-bottomed suspension bridge that sits 180 metres above the ground at the Shiniuzhai National Geopark in Pingjiang county, in central China's Hunan province on Thursday (24 September 2015). The 300 metre-long suspended bridge, which apparently sways in the wind, spans a chasm at the national park, popular with tourists for its unique rock formations and geography. Walkers see clear, stomach-churning views of the ground 180 metres below. Park management authorities added a small section of glass last year but decided to transform the entire length of the crossing. The floor is made of a double layer of glass and is 24mm thick in total. (Photo by Jiao Zi/Imaginechina)

The eastern gorilla has been listed as critically endangered, making four of the six great ape species only one step away from extinction, according to the International Union for the Conservation of Nature's Red List of Endangered Species, released Sunday Sept. 4, 2016. For the gorillas of the Congo, where the majority of the population lives, conservation will be a struggle because of the unstable political situation, said primatologist Russell Mittermeier, Executive Vice Chair of Conservation International and Chair of IUCN's Primates Specialist Group.

In this August 29, 2016 photo, tape holds together an election campaign banner for radical activist candidate Lau Siu-lai, which was slashed days ahead of legislative elections, in Hong Kong. A new crop of radical activists are challenging both pro-Beijing rivals and Hong Kong's mainstream pro-democracy parties for seats in the Legislative Council. A series of vandalized posters are a sign that the elections are the most contentious since the 1997 British handover of the city to China. (Photo by Kin Cheung/AP Photo)





This August 12, 2015 photo provided by the Illinois Department of Natural Resources shows IDNR biologist Nerissa McClelland holding alligator gar collected during a sampling survey at Powerton Lake in Powerton, Ill. The alligator gar is a toothy giant that can grow longer than a horse and heavier than a refrigerator. The fearsome-looking prehistoric fish plied U.S. waters from the Gulf of Mexico to Illinois until it disappeared from many states half a century ago. Persecuted by anglers and deprived of places to spawn, the alligator gar – with a head that resembles an alligator and two rows of needlelike teeth – survived primarily in southern states in the tributaries of Mississippi River and Gulf of Mexico after being declared extinct in several states farther north. To many, it was a freak, a “trash fish” that threatened sport fish, something to be exterminated. But the once-reviled predator is now being seen as a valuable fish in its own right, and as a potentially potent weapon against a more threatening intruder: the invasive Asian carp, which have swum almost unchecked toward the Great Lakes, with little more than an electric barrier to keep them at bay. Efforts are now under way to reintroduce the alligator gar from Illinois to Tennessee. (Photo by Illinois Department of Natural Resources via AP Photo)

This picture taken on May 29, 2016 shows Vientiane Rescue volunteers helping an injured motorcycle driver following an accident under the influence of alcohol in Vientiane, Laos. Founded in 2010 by a group of foreigners, “Vientiane Rescue” is a much needed lifeline for those in need of urgent medical care where poorly maintained roads, dilapidated vehicles, an increase in motorcycle use and the widespread prevalence of drink driving makes Vientiane one of Asia's most precarious capitals for road deaths.

Gunmen and suicide bombers went on a killing spree in Paris on November 13, attacking a concert hall, bars, restaurants and the Stade de France. Islamic State jihadists operating out of Iraq and Syria released a statement claiming responsibility for the coordinated attacks that killed 129 people and left 352 others injured.

The giant metal structure sits 330ft above the ground on the roof of a 22 storey office block in Dutch capital Amsterdam on September 6, 2016. Tourists sit in a playground-style chair as they propel themselves them over the edge of the building with only thin-air between them and the ground below. Engineers spent several years designing and building the breathtaking swing. By being fixed to the top of a building it reaches new heights – dwarfing other swings around Europe but trailing behind the 1,150ft high mechanical rides at the Stratosphere Hotel in Las Vegas, Nevada.
