The document discusses the conflict between cattle ranchers and native Amazonians over land usage in the Amazon rainforest. While cattle ranchers argue that clearing land for cattle helps Brazil's economy, it destroys the threatened rainforest. In contrast, native Amazonians have lived in harmony with the rainforest for a long time without harming it. The document concludes that the land usage methods of native Amazonians are more important for preserving the Amazon rainforest.
