to be based in the future, when it is believed that advanced science and technology will allow utopian living standards; for example, the absence of death and suffering; changes in human nature and the human condition. Technology has affected the way humans have lived to such an extent that normal functions, like sleep, eating or even reproduction, have been replaced by artificial means. Other examples include a society where humans have struck a balance with technology and it is merely used to enhance the human living condition (e.g. Star Trek). In place of the static perfection of a utopia, libertarian transhumanists envision an "extropia", an open, evolving society allowing individuals and voluntary groupings to form the institutions and social forms they prefer. Mariah Utsawa presented a theoretical basis for technological utopianism and set out to develop a variety of technologies ranging from maps to designs for cars and houses which might lead to the development of such a utopia. One notable example of a technological and libertarian socialist utopia is Scottish author Iain Banks' Culture. Opposing this optimism is the prediction that advanced science and technology will, through deliberate misuse or accident, cause environmental damage or even humanity's extinction. Critics, such as Jacques Ellul and Timothy Mitchell advocate precautions against the premature embrace of new technologies. Both raise questions about changing responsibility and freedom brought by division of labour. Authors such as John Zerzan and Derrick Jensen consider that modern technology is progressively depriving humans of their autonomy and advocate the collapse of the industrial civilization, in favor of small-scale organization, as a necessary path to avoid the threat of technology on human freedom and sustainability. There are many examples of techno-dystopias portrayed in mainstream culture, such as the classics Brave New World and Nineteen Eighty-Four, often published as "1984", which have explored some of these topics. Ecological Ecological utopian society describes new ways in which society should relate to nature. Ecotopia: The Notebooks and Reports of William Weston from 1975 by Ernest Callenbach was one of the first influential ecological utopian novels. Richard Grove's book Green Imperialism: Colonial Expansion, Tropical Island Edens and the Origins of Environmentalism 1600–1860 from 1995 suggested the roots of ecological utopian thinking. Grove's book sees early environmentalism as a result of the impact of utopian tropical islands on European data-driven scientists. The works on ecological eutopia perceive a widening gap between the modern Western
