Buell (2004: 110) suggests that "people have entered a world in which the robust exercise of their power to modify nature has made their past actions increasingly into their present fate-or, better, not just their present fate, but the fate of all life forms on the planet." What message is Buell attempting to convey with this statement? Describe the impact that humanity has had upon the natural environment, and provide specific examples. What are the implications of this statement?

Please help and answer all questions. Much help is appreciated. Thanks!
