Thousands of illegal goldminers are destroying the land of the Yanomami indigenous people in the northern Amazon.
They bring violence and infectious diseases to the communities living there, and are poisoning the rivers and fish with mercury.
Some Yanomami are uncontacted - they avoid contact with outsiders, including other Yanomami. Uncontacted tribes are the most vulnerable peoples on the planet and the invaders could wipe them out.
Davi Kopenawa Yanomami, a shaman and a leader of the Yanomami people, says:
We Yanomami and Ye'kuana people do not want mining on our land. We are extremely worried.
Mining won't bring any benefits to us - only disease, violence and death.
Bolsonaro said that there's a lot of land for few Indigenous people, but those "few" Indigenous people are looking after the forest for the whole world.
We need to pressure the government. Together, we are strong.
