Cheng Liping, whose husband Ju was onboard Malaysia Airlines Flight MH370 which disappeared on March 8, 2014, shows a picture of she and her husband together and an old card with a message given by her husband, at a park near her house where she and her husband used to visit during an interview with Reuters in Beijing July 24, 2014. Cheng said her life has been totally changed since the incident. Their two little sons, who don't know about this incident, keep asking her when their dad is coming back. Six months after Malaysia Airlines Flight MH370, with 239 mostly Chinese people on board, disappeared about an hour into a routine journey from Kuala Lumpur to Beijing March 8, loved ones of missing passengers derive what comfort they can from what's left behind after the world's greatest aviation mystery. More than two dozen countries have been involved in the air, sea and underwater search for the Boeing 777 but months of sorties failed to turn up any trace – even after narrowing the search area to the southern Indian Ocean – long after batteries on the black box voice and data recorders had gone flat.

Pangolins in Crisis: Brent Stirton, South Africa; 1st place, Natural world and wildlife. “Pangolins are the world’s most illegally trafficked mammals, with an estimated one million trafficked to Asia in the last 10 years. Their scales are used in traditional Chinese and Vietnamese medicine, and their meat is sold as a high-priced delicacy. As a result, pangolins are listed as critically endangered and anyone who trades or consumes them is breaking the law. This body of work exposes the trade, while exploring aspects of illegality and celebrating the people who are trying to save these animals”.
