What impact do human activities have on caves?

• A. Increased cave humidity
• B. Pollution and physical damage to delicate formations
• C. Greater biodiversity
• D. Expansion of cave systems

Answer: (B)

Human activities significantly impact caves primarily by causing pollution and physical damage to the delicate formations found within these ecosystems. Caves are unique environments that often develop intricate mineral formations, such as stalactites and stalagmites, which can take thousands of years to form. When people engage in activities like mining, tourism, or littering, they can introduce harmful substances into the cave, leading to pollution that can affect both the cave environment and the species that inhabit it. Additionally, physical damage can occur from reckless behavior, such as touching or climbing on formations, which can lead to breakage or alteration of these structures. The biodiversity within caves is often fragile, and any disruption can lead to a decline in various species that rely on the cave for their habitat. Therefore, understanding these impacts is crucial for the preservation and protection of cave ecosystems. This focus on preservation stands in contrast to the other options, which do not accurately reflect the negative consequences of human activities on caves.
