The Gaia Hypothesis

It is Time to Respect Mother Earth!

earth-762477In the 1960’s James Lovelock during his work for NASA on methods of detecting life on Mars, formulated the Gaia Hypothesis (named after the Greek supreme goddess of Earth). Based on the idea that Earth is a self-regulating living system, a complex entity involving the Earth’s biosphere, atmosphere, oceans, and land, in totality regulates the conditions on the planet to make its physical environment (in particular temperature and chemistry of the atmosphere) on the planet more hospitable to the species which constitute its “life”.

For example, when atmospheric carbon dioxide levels naturally rise as with volcanic eruptions, the biomass of photosynthetic organisms increases and removes the excess carbon dioxide from the atmosphere. Since life started on Earth, the energy provided by the Sun has increased by 25% to 30%, however the surface temperature of the planet has remained remarkably constant when measured on a global scale. With his initial hypothesis, Lovelock’s arguments were:

* The global surface temperature of the Earth has remained constant, despite an increase in the energy provided by the Sun.
* Atmospheric composition remains constant, even though it should be unstable.
* Ocean salinity is constant.

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.

Although almost completely ignored by the scientific community until the late 1970’s, the Gaia Hypothesis has since been supported by a number of scientific experiments and provided a number of useful predictions, and hence is properly referred to as the Gaia Theory.

Well, if we did nothing at all to counteract the effects of what we as a species do to this planet, the Earth would eventually cure itself of global warming, pollution and other ills without any help from us, which would take many hundreds of thousands of years. Along the way Mother Nature just might just be a little tired of all that extra work we put her through and angrily announce “the spankings will now begin!”

Or worse still, for the sake of her remaining species, give up on us entirely and kick our butts to the curb.

It’s time to stop messing with Mother Nature and help out alittle around the house.

    Lovely scientific intro to an honest message!
    I have a friend that preaches the coming of a mass extinction. Not due to meteors or glaciers, but to human error. It is time to slow down the processes we have started and try and make a difference.

    Linda, I’ve heard about this Gaia Hypothesis, the well-known ecological hypothesis before. Honestly, it’s a very true and fascinating facts about the Earth…
