TOPSHOTS An environmental activist blocking the site of a proposed dam in the Sivens forest, comforts a colleague after being arrested following clashes between activists and Gendarmes on March 4, 2015 in the nearby town of Gaillac, southwestern France. The activists tried to force a blockade by pro-dam farmers in order to supply foods to the Zadists ? the name given to the activists occupying the site "zone to defend," or ZAD. Farmers argue that the dam will provide much-needed irrigation for their fields. Anti-dam say the proposed dam poses a huge environmental threat to the biodiverse Sivens wetland.
