• increased skin cancer diagnosed cases 
• elevated levels of fossil fuel emissions
• larger amount of infectious diseases

Infer which of the following is an increase in Earth’s average temperature from the buildup of carbon dioxide and other gases in the atmosphere

Carbon Dioxide is important in our atmosphere because it is required for photosynthesis and traps some heat, keeping the Earth warm. However, human produced carbon dioxide is a problem because it

• leads to higher global temperatures.
• disrupts the natural cycling of other greenhouse gases
• add too much carbon dioxide to the oceans
• causes uncontrolled photosynthesis

DDT and other pesticides used over 50 years ago are still affecting the environment today. Scientists have found these substances in recent glacier runoff. Glacier runoff occurs during the summer, when precipitation that has fallen on glaciers during the winter is released. Ice layers from existing glaciers have been analyzed. The results of this analysis show that the concentrations of DDT and other pesticides were highest about 10 years after the use of these substances was banned. This information shows that 

• DDT and other pesticides cause glacier runoff during the summer.
• it takes humans over 50 years to analyze a glacier.
• the decision of one human generation may have an impact on future generations
• precipitation helps to break down pesticides

- Some exotic plants, like the kudzu, were imported to the United States as ornamental plants. This ornamental plant was used to help reduce soil erosion because it grew in a wide range of conditions and soil types. Because it is a rapidly growing plant it has taken over many native species and caused which of the following to occur?

• A decrease in the amount of biodiversity. 
• A decrease in the rate of cellular respiration.
• An increase in the amount of surface runoff
• An increase in the habitat for native species.

If a scientist discovers a new synthetic chemical that appears to have many potential uses, why must society be extremely cautious after the new chemical is manufactured?

• The scientist's work may be flawed, and his work must be verified.
• The chemical may be too expensive to manufacture for the general population
• Harmful problems for individuals and the environment may not be initially known.
• The best use may not be immediately obvious, and the chemical may be wasted.

Fossil fuels such as coal, oil, and natural gas supply much of the world's energy. However, these fuels have a tremendous negative effect on the environment. Which of the following would be the best strategy to alleviate this problem

• Impose fines on individuals that overuse fossil fuels and use the money for environmental cleanup
• Educate society on the harmful effects and gradually replace fossil fuels with alternative renewable resources.
• Fund scientific research for discovering new energy sources and use the remaining supply of fossil fuels until then.
• Create an environmental policy that would ban the use of all fossil fuels due to the negative environmental effects.

The activities that take place to meet human needs can often be harmful to ecosystems. By developing sustainable practices, however, we can help protect our environment. Which of the following changes would be most helpful in reaching sustainability

• Building more water treatment facilities 
• Planting trees to replace those that are cut down by logging
• Tilling soil to improve soil fertility and increase crop production
• Using natural gas for fuel instead of burning petroleum

- The choices that humans make every day affect the environment. Sometimes, our lifestyles can harm the environment rather than protect it. Which of the following would be most helpful in protecting the environment and achieving sustainability? 

• Buying paper products made from harvested trees
• Buying fewer mass produced products
• Using natural gas as a fuel source instead of petroleum
• using solar power to generate electricity
