The Russian attacks on Ukraine are not just about human casualties. The ravages of war are tearing through forests, rivers, and steppes, wiping out wildlife and rare species in national parks and nature reserves across the country. An environmental journalist travels through the devastated land, documenting the ecocide unfolding in the heart of Europe. Along the way, she meets scientists who have refused to abandon their work despite the daily threat of explosions. Together, they record the sounds of a disappearing landscape and compare them with pre-war recordings. The voice of nature itself becomes evidence of war crimes.
