2 Bilhões de Anos Atrás: Quando o OXIGÊNIO se Tornou uma Ameaça Mortal

How could oxygen have nearly destroyed life on Earth? Today, this gas makes our existence possible, but 2.4 billion years ago it was one of the most lethal poisons the biosphere had ever produced. In this documentary, we travel to the Great Oxidation Event, one of the most extreme crises in Earth's history. A global chemical shift that transformed the oceans, altered the atmosphere, and may have led the planet to an ice age that lasted hundreds of millions of years. What will you discover in this documentary? ► Early Earth before the emergence of oxygen ► The birth of oxygenic photosynthesis ► Banded iron formations and the geological evidence of the catastrophe ► How oxygen poisoned the oceans and changed the atmosphere ► The Huronian glaciation and Earth transformed into a snowball ► Why this crisis made complex life possible 👉 Subscribe here:    / @geoterra1   📩 Contact: [email protected] ⚠️ This documentary is for educational and scientific dissemination purposes.
