Final answer:
Ozone depletion is not limited to the U.S and has global implications, affecting human health and ecosystems worldwide.
Step-by-step explanation:
Ozone depletion is not only a problem for the U.S but has global implications. The ozone layer, which protects the Earth from harmful UV radiation, has been significantly depleted due to the release of chlorine and bromine gases from human activities. While the largest and most severe depletion occurs over Antarctica, there is also general depletion observed over other parts of the world, indicating that the effect is global. Ozone depletion increases the risk of skin cancer, disrupts ecosystems, and affects human health worldwide.
