Based on satellite images from environmental agencies, Brazilian based NGO Imazon reports that 78 percent of logging that took place between August 2011 and July 2012 was illegal.
Nearly 122,337 hectares of rainforest in Brazil was illegally logged during the time frame. The amount of illegal logging that took place was 151 percent higher than the 48,802 hectares of rainforest that was illegally logged the year before.
During the year, 34,902 hectares of licensed, legal logging took place, which means that illegal logging cut down 3.5 times more timber than legal logging in Brazil.
