The rainforest vivarium hits 1 year old, but something had caused an extinction event. The cause of the species disappearances was not known, but after researching the state of the ecosystem and its biological relationships further, the rainforest provided me with the clues I needed to piece the puzzle together. Hope you enjoy this Season 3 Finale of my Ecosystem Vivarium Series. Ant love forever! This video was shot in 4K Ultra HD resolution.
