1. Human activities such as can have negative impacts on the environment.

2. Resources need to be protected because:

• there is a limited number of resources available on the planet
• there is an unlimited number of resources available on the planet
• resources are evenly distributed across the planet
• resources will adjust over time to meet the needs of people

3. In the year 2000, which country used the most copper?

• China
• India
• United States

4. What is the overall trend of China's use of copper?

• There is no change in the amount of copper used by China.
• There is no overall trend in China's use of copper.
• There is an increase in the amount of copper used by China.
• There is a decrease in the amount of copper used by China.

5. Which country uses the least amount of copper over all the years displayed?

• China
• India
• United States
• Rest of the World

6. One of your classmates makes the following claim:



“Copper use and population growth happen at the same time.”



Which of the following statements best support their claim?

• Copper mines are found over the world, with the greatest amount of production from in Chile and Peru.
• China’s copper usage has increased dramatically, and so has their population.
• The United States has grown in population, but their copper consumption has fallen in recent years.
• India’s copper usage has remained nearly the same for the last 10 years, even though their population has grown.

7. It appears that population growth is tied to growth in copper consumption.

8. Given the data provided, which statement is the most accurate, regarding China’s resource consumption and population growth?

• China’s population has decreased, but their copper consumption has increased rapidly.
• China’s copper consumption has increased at a faster rate than their population growth.
• China’s copper consumption has decreased as their population has grown.
• China’s copper consumption has increased at the same rate as their population growth.

9. What piece of evidence would help to connect China’s copper consumption and population growth to an impact on Earth’s systems?

• Copper mining has become more efficient over recent years, as mines have expanded and larger industrial complexes have been built to process copper.
• Sulfides and other toxic gases that are created from copper mining and extraction are often reclaimed and re-sold or reused in other ways.
• China’s consumption of copper is greater than their ability to produce it, so it is often shipped from South America on cargo ships that pollute the ocean.
• China has recently implemented laws with steep fines for industrial pollution, after decades of growth in greenhouse gas emissions.

10. Write a claim to connect China’s copper consumption, population growth, and the effect that this might have on Earth's Systems.

11. Cite evidence that supports your claim that connects China’s copper consumption, population growth, and the effect that this might have on Earth's Systems.

12. Explain the reasoning to support your claim with your evidence that connects China’s copper consumption, population growth, and the effect that this might have on Earth's Systems.
