Famous quotes containing the words planetary and/or system:

    “We cannot cheat on DNA. We cannot get round photosynthesis. We cannot say I am not going to give a damn about phytoplankton. All these tiny mechanisms provide the preconditions of our planetary life. To say we do not care is to say in the most literal sense that “we choose death.””
    —Barbara Ward (1914–1981)

    “Loving feels lonely in a violent world,
    irrelevant to people burning like last year’s weed
    with bellies distended, with fish throats agape
    and flesh melting down to glue.
    We can no longer shut out the screaming
    That leaks through the ventilation system ...”
    —Marge Piercy (b. 1936)
