What is the greatest potential environmental threat to Oceania?

Question

Quizplus · Accepted Answer

Climate change is the greatest potential environmental threat to Oceania, as rising sea levels caused by global warming could lead to the flooding of low-lying islands and destroy habitats of various endemic species in the region. It could also trigger more extreme weather events, alter ocean currents and acidity levels, and cause changes in food chains that support fisheries and other industries. While other environmental issues like desertification, coastal pollution, grassification, and smog may also pose challenges, they might not have as significant an impact as climate change in Oceania.
