Question

which option identifies ways that people positively affect earths resources?

• use cars that emit fewer harmful gases, build dams, and stop using all resources
• stop using all resources, increase mining efforts, and halt the runoff of factory waste into rivers and streams
• build dams, use cars that emit fewer harmful gases, and halt the runoff of factory waste into rivers and streams
• increase mining efforts, build dams, and use cars that emit fewer harmful gases

Explanation:

1. Analyze each option:

• Option 1: "stop using all resources" is impossible and unrealistic, so this is invalid.
• Option 2: "increase mining efforts" depletes resources, and "stop using all resources" is impossible, so this is invalid.
• Option 3: Building dams can manage water resources sustainably, low-emission cars reduce pollution, and halting factory waste runoff protects water resources—all are positive actions.
• Option 4: "increase mining efforts" is harmful to Earth's resources, so this is invalid.

Answer:

build dams, use cars that emit fewer harmful gases, and halt the runoff of factory waste into rivers and streams
