Earth is Lucky with Life-assisting Plate Tectonics

A new study reveals Earth's size is just big enough to support the Plate Tectonics which assist life. Plate Tectonics allows for the recycling of the planet's crust which keeps carbon dioxide at relatively stable levels. Excess gases constantly "weather" away the new rocks which in turn are replaced by newer rocks.
