    gaia hypothesis essay

    It is an ironic fact that a theory about life on Earth should begin from an exploration of outer space.What could you learn from mankind’s accomplishments and failures?Since every hypothesis takes the form of an if/then statement, the Gaia Hypothesis namely is an if/then statement.According to Lovelock, if life is a global integrity, its presence can be detected through a change in the chemical composition of the planet’s atmosphere. His job was to design instruments, capable of detecting the presence of life, which could be sent on a spacecraft to Mars.For example, methane and oxygen will react with each other very easily, and yet they are both present in the atmosphere.He proposed that a top-down view of the entire planet be employed.Begin this TED Study with a fascinating read that gives context and clarity to the material.The Earth was 77% nitrogen, 21% oxygen, and a relatively large amount of methane.James Lovelock is famous for developing the controversial Gaia hypothesis, but has also made major contributions to medicine, environmental science, atmospheric chemistry and the exploration of space.I have even met people who have a deep fear of being in nature.
    • In order to evaluate the above statement effectively, this essay will examine the. Similarly to Deep Ecology, Lovelock's Gaia Hypothesis takes a holistic view of.
    • The second example is the Gaia Hypothesis. This theory brings together proof that the dense network of mutual interactions between the organic and inorganic.
    • Lovelock and Lynn Margulis formulated the Gaia hypothesis, and Margulis had a further extraordinary insight into the origins of complex life on the planet.
    • Jan 19, 2012. I wrote the following brief essay in response to literary agent John. Lovelock initially put forth the Gaia hypothesis to explain how life on Earth.

    Its authors are the British chemist James Lovelock and American microbiologist Lynn Margulis.If it held no life, the planet should have an atmosphere close to the chemical equilibrium state, as determined by chemistry and physics.Ecologists go out in the field to quantify nature, to break it down into numbers which are then placed in computers to tease apart the complex inter-relationships in the living world.But the hypothesis has turned into a theory, still not fully accepted by other scientists but not scorned either.In the mid-1960's, Dr James Lovelock was approached by NASA, who asked him for help in searching for life on Mars.Or rather reddish pink, as James Lovelock corrected me when I showed him an earlier version of this essay.Through his letters, documents, photographs and drawings, some of which are featured below, we get a unique insight into his creative mind and charismatic personality. Object no: 2012-118/3 © Science Museum, James Lovelock This draft of Lovelock’s first book was written at his holiday home in Adrigole, Ireland.Lovelock initially put forth the Gaia hypothesis to explain how life on Earth has persisted for 4 billion years despite a 30% increase in the Sun’s intensity over that same interval. Lacking a conscious command-and-control system, Lovelock and Margulis demonstrated that Gaia uses feedback loops to track and adjust key environmental parameters.Thus, it is a good starting point for our study of oceanography, providing a broad overview of the kinds of processes that will interest us throughout the semester.The Gaia Paradigm describes a productive confluence between scientific understandings of Earth as a living system with cultural understandings(ancient and new) of human society as a seamless continuum of that system.

    The book was published in 1979, 11 years after his first scientific paper on Gaia.Lovelock suggested using such combinations detected in other planets' atmospheres would be a relatively reliable and cheap way to detect life, which many biologists opposed at the time and since.Lovelock suggested that life on Earth provides a cybernetic, homeostatic feedback system operated automatically and unconsciously by the biota, leading to broad stabilization of global temperature and chemical composition.James Lovelock is among the planet’s most interesting and productive scientists.She also originated the theory of the eukaryotic cell arising as a result of endosymbiotic cell capture.Lovelock introduced the concept of geophysiology, indicating a systematic approach to the sciences about the Earth.We have come to a point in the history of our civilisation where our relationship to nature seems to be more of one of destruction than of nurturance and respect.
