When will life on Earth end? Scientists now have the ‘exact date’

A new study predicts Earth's oxygen will vanish in a billion years. Toho University researchers used NASA models for this finding. The aging sun will cause water evaporation and temperature rise. This will disrupt the carbon cycle and kill vegetation. Earth's atmosphere will then resemble its early state, rich in methane. Complex life will struggle to survive this deoxygenation event.
