The Matses people live in Peru and Brazil along the Amazon River. Their population is estimated between 1500-3000 people. They worship jaguars and use body paint in their traditions. They have faced conflicts with neighboring tribes and were bombed by the Peruvian Air Force. Factors that are causing their decline include a lack of access to healthcare as there are few medical professionals and limited transportation of medical supplies to their remote communities. This has led to a 10% annual death rate from untreated illnesses like malaria, hepatitis, and parasites in the water supply.
