Human impact on biogeochemical cycles

    • How are biogeochemical cycles affected by global activities?

      Global-scale alterations of biogeochemical cycles are occurring, from activities both in 38 the U.S. and elsewhere, with impacts and implications now and into the future. 39 Global CO 2emissions are the most significant driver of human-caused climate change. But 40

    • What will be the fate of the biosphere?

      The fate of the biosphere, including humanity, depends on a reaffirmation by all humans of all cultures and religions of the global importance of a planet-wide conservation of the Earth’s biotic heritage.

    • Why are humans dependent on the biosphere?

      We are totally dependent on the biosphere for food, oxygen, and other necessities of life. mans are one of the latest results of biological evolution operating over a long period of Geologic Time. We find ourselves on Earth, after 4.5 billion years of Earth history by chance, not by design.
