The police have cracked down hard on demonstrators in the southern Chilean region of Aysén, who have been protesting the area's isolation and high local prices of fuel and food for the past two weeks.
Following numerous warnings issued by geologists, health scientists and environmental experts throughout the United States, Europe is now well aware of the high ecological and health risks associated with the exploitation of shale gas fields.
