Rudi Putra, Indonesia

The Goldman Environmental Prize was established in 1989 by late San Francisco civic leaders and philanthropists Richard and Rhoda Goldman.
Prize winners are selected by an international jury from confidential nominations submitted by a worldwide network of environmental organizations and individuals.
Often referred to as the Nobel Prize for the environment, it is awarded six environmental activists from each of the world's six continents who have worked against all odds to protect the environment and their communities. The price recognises grassroots environmental achievements such as stopping fracking, dams, palm oil development, land grabs, coal mining, toxic waste dumps.
The world's biggest prize for environmental activism
Currently celebrating its 25th anniversary year, the prize is awarded annually and with an individual cash prize of $175,000 (roughly £100,000), it is the largest award for grassroots environmental activism.
"For the past 25 years, the Goldman Environmental Prize has honored heroic grassroots environmentalists for their achievements around the world and this year is no exception", said David Gordon, executive director, Goldman Environmental Prize.
"From fracking to palm oil development, the 2014 Goldman Prize recipients are not only tackling some of the world's most pressing environmental problems; they are also achieving impressive environmental victories and inspiring others to do the same", he adds.
The prizes will be awarded this evening at the San Francisco Opera House.
