While individuals who live traditional lifestyles deep inside the jungle do not use contemporary technology or resources, those who live in places such as Rio de Janeiro enjoy a lifestyle similar to that of other cities across the world. The majority of people in the Amazon live in places that have been industrialized to some extent. In these areas, they build their houses with wood and plaster, grow vegetables and fruits for food, keep livestock such as cows and pigs for milk and meat, and make tools out of stone and bone. People in the Amazon live under the control of many institutions. There are indigenous tribes with their own governments and laws who live in small villages within the forest, often near clearings where they hunt and fish. Other tribes are nomadic and only stay in one place for a few years before moving on. Still others sell their labor in towns and cities across Brazil and beyond. The Amazonian people I met were very friendly and happy. They told me about all the animals they had eaten and how they used the plants around them to heal themselves when they got sick. They also shared their knowledge of the forest with me, showing me special places where we could find certain flowers or trees. Over time, I was able to learn everything from doctors without borders to provide health care using modern methods, to help the people who lived in the Amazon avoid going back to a life of poverty.
