Question
**Human Activities and Earth's Atmosphere**

Evidence from scientific studies supports the claim that human activities are contributing to the increasing average global surface temperature on Earth, as observed over the past 100 years. The concentration of greenhouse gases in Earth's atmosphere has increased during this time and is thought to be the major cause for changes in global climate. Graph 1 represents the relative contribution of human activities that are likely causing global climate change. Graph 2 represents the relative amounts of various greenhouse gases in the atmosphere.

**Graph 1: Contribution of Human Activities to Global Climate Change**

This pie chart shows the following contributions:
- Burning fossil fuels: 49%
- Industrial processes: 24%
- Deforestation: 14%
- Agriculture: 13%

**Graph 2: Relative Amounts of Greenhouse Gases in Atmosphere**

This pie chart shows the following distribution:
- Carbon Dioxide: 72.7%
- Methane: 16.6%
- Nitrous Oxide: 7.6%
- Chlorofluorocarbons: 2.7%
- Sulfur hexafluoride: 0.4%

**Question 7**

An environmental group recommends a way to help slow global climate change. Based on data in Graph 1, which activity would have the GREATEST positive impact on slowing global climate change?

Options:
A. Limiting the clearing of land for building houses
B. Using renewable energy sources instead of fossil fuels
C. Using organic farming methods instead of harsh chemicals
D. Collecting wastewater from industry instead of releasing into rivers

*(The answer is to be inferred using the information in the graphs and text.)*

Expert Solution
Step 1

The "greenhouse effect," or warming which happens when the environment retains heat radiation from the Earth that is radiating toward space, is what scientists believe is responsible for the increase in global warming which has been seen since the middle of the 20th century.
