However, two cases, Spotted Owl and Hydraulic Fracturing, contain excellent examples. In the case of the Spotted Owl, the case applies to both conservation and preservation. Originally, conservationists committed to saving spotted owl habitat followed the ethic of preservation. They wanted to generally stop logging around Spotted Owl habitat. They wanted to keep nature intact there. As the case progressed, it unfortunately became clear that the logging companies would not be content with this as they continued to push for policy in their favor. Environmentalists then opted for conservation by designating the Spotted Owl an endangered species in 1990. They opted for a radius around Spotted Owl nests, which reduced logging but did not completely stopped. They enabled the passage of laws like the Northwest Forest Plan, which ensured that companies planted new trees when they felled one that leaned toward conservation (Layzer). In the case of fracking, opponents of fracking use land ethics to oppose it. They want to prevent pollution from fracking and would rather do that than use fracking to recover oil, which is better than oil drilling, but still not a good thing.
