Final answer:
Liberalism and conservatism are ideologies on opposite ends of the political spectrum. Liberals prioritize social progress and government intervention, while conservatives prioritize traditional values and limited government intervention.
Step-by-step explanation:
Liberalism and conservatism are ideologies that exist on opposite ends of the political spectrum. Liberal ideologies are traditionally placed on the left and conservative ideologies on the right. Liberals prioritize social progress, individual rights, and government intervention in advancing equality and justice. On the other hand, conservatives prioritize traditional values, limited government intervention, and free market economics. The conservation movement in the United States emerged as a response to rampant resource exploitation in the post-Civil War era. Conservationists were split between utilitarian conservation and preservation ethics. Utilitarian conservationists, led by Gifford Pinchot, believed in the efficient management of natural resources for the greatest good of the greatest number. Preservationists, led by John Muir, advocated for the protection of parklands and wilderness for their inherent value. Radicals, as mentioned in the context of conservatism, represent a more extreme or radical form of conservatism. They may prioritize short-term financial gain and be willing to risk environmental damage for economic benefits. However, it is important to note that this approach is not inherent to conservatism and can be found across the political spectrum.
