"Deep in the Amazon, sound designer Eric Terena has been capturing the sounds of the rainforest while sitting silently beneath the dense, towering treetops with his recording equipment. He has noticed some huge changes.
"What the environment once spoke, what biodiversity once sang, has shifted to sounds from industrial projects that have arrived in our territories," said Terena, co-founder of Mídia Indígena, a Brazilian media and communications network which promotes and preserves Indigenous cultures.
His words describe more than a change in sound—they show how nature is gradually being replaced by machines. Ancestral songs have been drowned out by industrial noise. Terena shares these changes using digital tools to bring local stories to global audiences, turning lived experience into climate knowledge."
