Grupo de los Cien

Grupo de los Cien

Founded in 1985, Grupo de los Cien is Mexico's most influential environmental advocacy group composed of more than 100 prominent personalities in the arts, culture and science.

Under the leadership of its president the writer Homero Aridjis, the group's efforts have lead to a ban on the capture and commercialisation of sea turtles in Mexico, legislation reducing the amount of lead in gasoline, daily notification in the press of air quality in Mexico city and official designation as sanctuaries of the nesting areas of the Monarch butterfly.

The group was able to thwart a project to build dams along the Usumacinta River in the Mayan area of the Mexico/Guatemala border and also led a successful campaign to stop the building of an airport extension in the Texcoco nature reserve.

In September 1991 the Group held a meeting of writers, scientists, representatives of indigenous peoples and environmentalists, The Morelia Symposium: Approaching the Year 2000, which led to the creation of an international network for defense of the environment: the Grupo de Los Cien Internacional. The Morelia Declaration was presented at the Earth Summit as a global statement by 896 intellectuals and environmentalists.
