Environmental problems are among the most serious issues people in my country face today. Nature has complex interdependencies. Any human meddling will cause a chain reaction with unanticipated effects. We have a moral duty to prevent extinction of any plant or animal species, no matter how worthless it may appear to us. There is nothing wrong with killing individual animals, as in hunting, as long as you don't kill so many that you threaten the population.
Nature is inherently beautiful.
When we see ugliness in the environment, it's caused by humans. Some of the people who are the most passionate about biodiversity loss are pretty naive about the facts. Since nature is inherently dynamic and unstable, human impacts on nature aren't that terrible a thing. Government restrictions on the use of private property are necessary in order to ensure that the environment will not be permanently harmed. We should be skeptical about scientists' assessments of biodiversity loss.
