Question

15 multiple choice 2 points what is considered the primary cause of earths current (sixth) mass extinction? human activities such as habitat destruction, pollution, and overexploitation of resources a global drop in oxygen levels due to ocean stagnation increased volcanic activity along tectonic plate boundaries natural fluctuations in solar radiation and temperature

Explanation:

Human activities like habitat destruction (e.g., deforestation for agriculture or urbanization), pollution (air, water, soil pollution harming species), and overexploitation (over - fishing, over - hunting) have led to a rapid decline in species populations. These are the main drivers of the current mass extinction. Global oxygen drop due to ocean stagnation is not the primary cause as human - induced factors act more directly. Increased volcanic activity along tectonic plates is a rare and not the main current cause. Natural solar and temperature fluctuations occur over long geological timescales and are not the main reason for the current rapid extinction event.

Answer:

Human activities such as habitat destruction, pollution, and overexploitation of resources
