“ The life of the plant began the long, slow process of
modulating and regulating the physical conditions of the
planet. The oxygen in today’s atmosphere is almost entirely
the result of photosynthetic living, which had its start with the
appearance of blue-green algae among the microorganisms”
Lewis Thomas, 1984
