The COP 21 summit…has so far declined to give a voice to the indigenous peoples most directly threatened by ecological catastrophe. This omission comes despite clear evidence that tribal peoples are the best conservationists of the environments in which they live…The Guajajara…have been involved in clashes with armed logging gangs, and even organised initial efforts to extinguish a huge fire…The Ka’apor… responded to illegal logging in their territory by forming an indigenous ‘army’ to fight back…The Guarani…continue to have violence inflicted on them for their attempts to hold on to their land against sugar cane and soya farmers and big cattle ranching operations…Tribal peoples are the…people most acutely affected by the destruction of the natural environment in which they live. Without the support of the international community, however, South America’s indigenous people and the Amazon regions in which they make their homes could be destroyed forever.
