change

I think that the changes in the Yanomami  tribes are ad because of the changes that happened during the gold rush like sicknesses brought over during the time which has killed many,the way that the gold finders killed them with guns and how the gold finders used mercury to find the gold easier and how that dramatically changes the  lives of people because it killed the fish and the water supply was polluted so the people would get sick because they relied on it to live.
