Abstract
In 2016, environmental matters attracted significant attention in Chile. The greatest development was Chile’s ratification of the Paris Agreement; the treaty was signed in September 2016 and finally adopted on 10 February 2017. Perhaps it was the toxic phenomenon of the red tide, which hit the archipelago of Chiloé in the Region of the Lakes (Región de los Lagos) between April and May 2016, that contributed to impressing political and public opinions.
