'Until my last drop of blood' - Amazon tribe vows to protect sacred land

In the heart of the Amazon, the Mura indigenous people have vowed to protect their traditional land amidst threats from farmers, logging and raging fires. A record number of wildfires have raged for weeks and are decimating the Brazilian Amazon, the world's largest tropical rainforest whose protection scientists say is critical to the fight against climate change. The blazes have nearly doubled this year compared with the same period in 2018, according to Brazilian officials, prompting a global outcry.
