    What is in bold is almost certain and fairly accurate. The underlined portions are relative and would likely overlap although I am not sure to what extent.

    Surface Of the Earth:

    71% water

    10% agriculture/farming/animals for profit

    9% forests and falling

    9% desert

    7.5% mountains (“Living In The Environment” by G.Tyler Miller ,Jr)

    3% urban areas (DEVELOPED)
