Based on oxygen's half-life in the atmosphere, animal life would last at most 100 million years after the loss of higher plants. [12] Some cyanobacteria and phytoplankton could outlive plants due to their tolerance for carbon dioxide levels as low as 1 ppm, and may survive for around the same time as animals before carbon dioxide becomes too ...
