Biosphere
link connecting the living world to the lithosphere and the rest of earth’s physical systems. thus, soil is the appropriate bridge between part III and part IV of this text.
today, we face crucial issues, principally the preservation of the diver- sity of life in the biosphere. patterns of land and ocean temperatures, pre- cipitation, weather phenomena, and stratospheric ozone, among many other geographic factors that have an impact on life, are changing as global climate systems shift. the resilience of the biosphere as we know
it is being tested in a real-time, one-time experiment. these important issues of biogeography are considered in part IV.
