The phrase "the last frontiers" refers to the untouched or uncharted territories, either literally or metaphorically, that lie at the outskirts or boundaries of existing knowledge, exploration, or development. It denotes the boundaries of human civilization or progress that have not yet been fully explored, tamed, or mastered.
In a literal sense, the last frontiers represent the remote regions of the world that are still relatively untouched by human presence, such as isolated islands, deep rainforests, or polar regions. These areas often possess unique ecosystems, wildlife, and natural resources that remain largely unknown or unexplored by humans. Scientists and explorers might venture into these untouched territories to conduct research, discover new species, or unlock the secrets of the natural world.
Metaphorically, the last frontiers can encompass areas of knowledge or endeavors that remain unexplored or unattained. It can refer to scientific, technological, or intellectual frontiers waiting to be reached, such as finding cures for certain diseases, exploring outer space, or understanding the complexities of the human brain. The last frontiers could also symbolize innovative ideas, unconventional solutions, or groundbreaking artistic creations that push the boundaries of existing conventions, pushing society forward and expanding the boundaries of human imagination and progress.
In essence, "the last frontiers" signify the undiscovered, uncharted territories, either physical or conceptual, that still hold the potential for further exploration, discovery, and development.
