Mexican President Andrés Manuel López Obrador, known as AMLO, presented before parliament a series of constitutional reforms among which there’s a proposal to modify Article 27 so that it prohibits open-pit mining.
In detail, his proposal calls for banning the granting of open-pit mining concessions and activities related to the exploration, exploitation, benefit or use of minerals, metals or metalloids using the open-pit method. To argue his case, López Obrador said that open-pit mining causes severe environmental damage and uses excessive water that could be supplied to water-scarce communities.
