Since the 1994 uprising, migration into the Lacandon Jungle has significantly increased, involving illegal settlements and cutting in the protected biosphere reserve. The Zapatistas support these actions as part of indigenous rights, but that has put them in conflict with international environmental groups and with the indigenous inhabitants of the rainforest area, the Lacandons. Environmental groups state that the settlements pose grave risks to what remains of the Lacandon, while the Zapatistas accuse them of being fronts for the government, which wants to open the rainforest up to multinational corporations. Added to this is the possibility that significant oil and gas deposits exist under this area.
