Aren't Pollard and Stephenson really suggesting that we abandon the struggle, acquiesce, go back to business as usual, eat, drink, be merry, or possibly take our own lives? Feb 7, 2014 - story of life's origin. Or is it Most leaders, officials and institutions behave as if the human enterprise is somehow remote from the environment; as if human expansion can go on forever; as if the Earth's resources and energy were limitless. 3 days ago - But ionizing radiation from space and from the natural geology of the Earth and in the food we eat and the water we drink can also contribute to cancer and aging. Oct 29, 2013 - It has baffled humans for millennia: how did life begin on planet Earth? Is life common in the Since all life on Earth is born of liquid water and sustained by liquid water, the absence of liquid water on Titan creates an environment that is completely inhospitable to terrestrial life. Any terrestrial life A typical M-dwarf star is so much less luminous than the Sun that an Earth-sized habitable planet with surface liquid water can only be sustained at one-tenth the Earth-Sun distance from the star. Feb 21, 2014 - These deep physical processes, these new qualities of our physical and geological environment, will impose special adaptive challenges and requirements for all life forms on Earth. The Earth's oceans contain more than 4 billion tonnes of uranium 238 which has a radioactive half-life of 4.47 billion years. Now After studying the environments of the oldest fossil-containing rocks on Earth in Greenland, Australia and South Africa, Chatterjee said these could be remnants of ancient craters and may be the very spots where life began in deep, dark and hot "The emergence of the first cells on the early Earth was the culmination of a long history of prior chemical, geological and cosmic processes.". On the surface of the Moon or Mars, humans would be exposed to only half the amount of cosmic radiation thanks to the natural mass shielding of being on a planetary surface. Chatterjee says, “When the Earth formed some 4.5 billion years ago, it was a sterile planet inhospitable to living organisms,” Chatterjee said. Others, such as ANU geologist Prame Chopra, know better. May 11, 2009 - And they were gathered in this shrine of science to discuss one question: can Homo sapiens – the primate species that has evolved to dominate the planet – survive? Let go of the pretense that with “giving up”? Considering the problems of adaptation The living organisms of those regions of Earth having the major “inlets”, or attractions, for cosmic influences will be taking the lead in evolving life's appropriate reactions or processes to these new conditions. Feb 8, 2013 - Testing Life's Cosmic Ubiquity. 6 days ago - Stop pretending that the crisis can be “solved,” that the planet can be “saved,” that business more-or-less as usual—what progressives and environmentalists have been doing for forty-odd years and more—is morally or intellectually tenable.
