Planetary Sciences

Famous quotes containing the words planetary and/or sciences:

    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)

    Letting a hundred flowers blossom and a hundred schools of thought contend is the policy for promoting the progress of the arts and the sciences and a flourishing culture in our land.
    Mao Zedong (1893–1976)
