Answer:The movie "2012" heavily depends on human lives and actions in several key ways. The entire narrative is structured around the human struggle for survival in the face of a global cataclysm. The plot follows individual characters and families as they navigate unimaginable disasters, highlighting their resilience, ingenuity, and capacity for both heroism and selfishness in extreme circumstances. The movie emphasizes the importance of human connection and relationships as characters must rely on each other to overcome obstacles. Furthermore, the central conflict revolves around the government's secret Noah's Ark project, a massive undertaking built by humans to save a select few, thus placing human decision-making and societal structures at the heart of who gets to survive. Ultimately, "2012" uses the backdrop of global destruction to explore fundamental questions about humanity's response to crisis, the value of individual lives, and the enduring human spirit in the face of overwhelming odds. Without the focus on human characters, their choices, and their desperate fight to live and rebuild, the movie would lose its core emotional and thematic impact.
