Describe two laws and one international treaty designed to conserve biodiversity.
a) What are the differences in health risks between developing and developed countries?
b) Why do those differences exist? The questions below are to see how much you know about our next topic, conservation of biodiversity. Don't google - just answer with what you already know.
a) What is the purpose of the Endangered Species Act? b) What's the difference between a native and an invasive species? c) What are some ways we have tried to preserve the biodiversity that we have? Why would a chapter on human health and environmental risk be in an environmental science class?
In recent years many scientific studies have shown the relationship between the global mean atmospheric
temperature at Earth’s surface and rising sea levels. The increases in the global mean atmospheric temperature during the past two hundred years have been accompanied by a gradual increase in sea level. The average rate of increase in sea level over the past 200 years is 2.5mm/yr. a) Calculate the expected increase in sea level, in meters, for the following lengths of time: 10 years, 100 years, 200 years. SHOW WORK b) Figure 19.13 on page 530 in the text presents historical CO2 levels. Use the graph to determine the net change in atmospheric Carbon Dioxide concentration between 100,000 years ago and present day levels. SHOW WORK. Re-read the opening story of Chapter 19 (p. 517-518). This story is more than just about polar bears. Explain the overall significance of the opening story.
When you are finished, head on over to the Activities page under Global Change and check the answers to your Chapter 19 Reading Questions. How has this chapter made you think differently about the products you purchase?
