Following the beginning of the industrial revolution, various environmentalists and philosophers began to speak out about our relationship with nature, and how we should treat it. Each person views differ but there is no doubt that all impacted the environmentalists of the future. This essay will look at three main players in environmental ethics: Immanuel Kant, Aldo Leopold and John Muir.

His ideas influence environmental ethics, where their emphasis in terms of progress and it can be applied in today’s ever changing world because he settled and moved philosophy beyond the debate between the rationalists and empiricists. He uses the natural
