VELAZQUEZ GARCIA, Mario Alberto. Perspectivas del movimiento ambiental en la frontera entre México y Estados Unidos: acciones y necesidades. Región y sociedad [online]. 2007, vol.19, n.spe, pp.171-197. ISSN 2448-4849.

Using political opportunity theory we will analyze the way in which American and Mexican environmental groups use the contradictions between a value system and a set of social practices; the sudden mishaps; the illegitimacy or vulnerability of a government; and the availability of an innovative frame of action that allows them to convey their protests and vindications, in order to determine their possibilities and limitations.
