Question

1 multiple choice 20 points which human activity can increase greenhouse gas production? planting trees. walking instead of driving. driving cars that use gasoline. using solar panels. 2 multiple choice 20 points what is one way to reduce the impact of chemical use on the environment. use fewer pesticides and fertilizers on crops. dump all the chemicals into the rivers and let the earth clean them up. use more gm crops that can withstand stronger pesticides. burn all the chemicals so they go through the atmosphere and out into space.

Explanation:

1. Question 1:

• Planting trees absorbs \(CO_2\) (a greenhouse gas), so it does not increase greenhouse gas production.
• Walking instead of driving reduces fossil - fuel use (which emits greenhouse gases like \(CO_2\) from gasoline combustion), so it does not increase greenhouse gas production.
• Driving cars that use gasoline: Gasoline combustion in car engines produces \(CO_2\) (a major greenhouse gas).
• Using solar panels is a renewable energy source and does not produce greenhouse gases during operation.

1. Question 2:

• Using fewer pesticides and fertilizers on crops: Pesticides and fertilizers can have negative environmental impacts (e.g., water pollution from fertilizer runoff). Reducing their use reduces this impact.
• Dumping all the chemicals into the rivers: This will cause water pollution (e.g., harming aquatic life, contaminating drinking water sources).
• Using more GM crops that can withstand stronger pesticides: This may lead to increased pesticide use (as stronger pesticides can be used) and potential negative ecological consequences (e.g., harm to non - target organisms).
• Burning all the chemicals: Burning chemicals can release harmful pollutants (e.g., toxic gases) into the atmosphere, which is bad for the environment.

Answer:

1. C. Driving cars that use gasoline.
2. A. Use fewer pesticides and fertilizers on crops.
