[听力文本资源] Ice caps and iceburgs are melting. Ocean levels are rising. Whatever is causing it, there's no longer any way to deny that global warming is for real. And it's by now well known that rising temperatures could have all sorts of environmental consequences. What's less well known is that global warming could have serious effects on global health, too. For example, warming could change patterns of infection, enabling diseases to spread outside their normally tropical zones. Rising temperatures could also cause heat waves resulting in thousands of deaths. Other possible effects are less direct.There's evidence that hotter conditions could harm crop yields, resulting in less grain and higher food prices. As demand increases in places like China and India, food shortages could lead to increased hunger and even famine. People living in the world's poorest areas would suffer the most. Finally, rising sea levels and water shortage caused by global warming could result in large migrations. And masses of people moving to the interior from the coast, or from rural to crowded urban areas, raises the risk for disease occurences of all sorts. Now our planet is warming. And the evidence is increasing that, concerning global health, serious problems might be on the way.[听力文本资源]1. [听力文本资源] What is the purpose of the passage?
