Friends of the Earth illegally planted trees to focus attention on the worldwide illegal cutting down of trees. Overnight 60 illegally planted trees appeared in the big cities of the Netherlands.
While planting six people had been arrested and some of the trees where confiscated.
Friends of the Earth Netherlands is part of the worldwide organisation FOE.
The outdoor campaign is made by Hallelujah and just won the Bronze Lion in the category Outdoor at the Cannes Advertising festival.
Update: if you want to do some environmental guerilla by yourself look at this: guerrillagardening.org.
