I did a field trip for language preservation in the Amazon, it was so weird the difference between the will to preserve culture and language from insider and outsider vs the willingness to learn and be part of global culture and learn Spanish / English. Night lectures were given in evening school for traditional language and then later for English. They were all expecting to enhance they quality of life and situation by learning English and work with tourist. After 5 years they were just able to present themselves. They were stuck between the to world belonging to none and kept in this position it was very special.
