One of the primary figures of the religion and environmentalism movement, Iranian Muslim philosopher Seyyed Hossein Nasr, details the theme of "man's total disharmony with his environment." Nasr believes that to overcome the environmental crisis there needs to be a recognition that "the whole of nature is descended from higher spiritual realms." According to Nasr, the desacralization of the West has led to the increase of ideology promoting dominion over the earth and its resources, which is contrary to Islamic thinking. According to conservationist and scholar Jonathan Benthall, Islam offers a useful perspective of environmentalism through two primary themes. The first being the "glory and logic of the cosmos and of the cyclical regeneration of life" that is visible through Qur'anic passages, particularly ones referencing stewardship ("khalifa)". The second theme Benthall references is the very environmental basis from which Islam was founded, "an environment where natural recourses, especially water, fruit trees, and livestock have always had to be carefully conserved to ensure human survival, a concern which is inevitably reflected in the Qur'an."
