FILE - In this July 6, 2012 file photo, candles are lit at the very spot where Dutch environmental activist Wilhem Geertman, a former religious missionary who helped poor farmers affected by illegal logging and mining, was killed allegedly in a robbery attempt in San Fernando city, Pampanga province, north of Manila, Philippines. A survey released Tuesday, April 15, 2014 - the first comprehensive one of its kind – says that only 10 killers of 908 environmental activists slain around the world over the past decade have been convicted.
