Final answer:
Aldo Leopold, an ecologist and environmentalist, created the 'Land ethic', indicating that the land should be included in the ethical framework of human society, with moral consideration given to all the parts of the natural world, to promote sustainable practices.
Step-by-step explanation:
The concept of the 'Land ethic' was created by Aldo Leopold, an influential American ecologist, forester, and environmentalist. In his seminal book A Sand County Almanac, published in 1949, Leopold articulated the idea that land, including soils, waters, plants, and animals, should be included in the ethical framework of human society. He posited that humanity should transition from viewing ourselves as conquerors of the land to seeing ourselves as members and citizens within a broader biological community. Leopold's land ethic extends moral consideration to all components of the natural world and advocates for respecting the integrity, stability, and beauty of the biotic community.
His philosophy helps move society away from the frontier ethic, which was characterized by the belief in unlimited resources and the prioritization of human needs. Instead, Leopold's land ethic fosters an environmental perspective that respects all parts of the natural world, regardless of their utility to humans, thereby promoting more stable biological communities and sustainable practices.
