Question

all of these activities cause greenhouse gas emissions. pick one from each side and describe an activity that could replace it and cause fewer greenhouse gas emissions.

Explanation:

To solve this, we analyze two activities (one from each side of the image) and their eco - friendly replacements:

Activity 1: Burning coal, oil, and gas (Top - right image)

• Original Activity: Burning fossil fuels (coal, oil, gas) for energy production in power plants, vehicles, or industries releases large amounts of \(CO_2\), \(CH_4\), and \(NO_x\) (greenhouse gases).
• Replacement Activity: Switch to renewable energy sources like solar, wind, or hydro - power. For example, a coal - fired power plant can be replaced with a solar power plant. Solar panels convert sunlight into electricity without emitting greenhouse gases during operation. The production of solar panels has a much lower carbon footprint compared to the continuous emission from burning coal.

Activity 2: Cutting down forests (Deforestation, Middle - right image)

• Original Activity: Deforestation for agriculture, logging, or urbanization reduces the number of trees that absorb \(CO_2\) (a key greenhouse gas) through photosynthesis. Also, when trees are cut and burned, they release stored carbon.
• Replacement Activity: Implement sustainable forestry practices or reforestation. For sustainable forestry, selective logging (only cutting mature or diseased trees) can be used instead of clear - cutting. Reforestation involves planting new trees in deforested areas. Trees absorb \(CO_2\) as they grow, helping to reduce the greenhouse gas concentration in the atmosphere.

Answer:

For "Burning coal, oil, and gas":

• Original Activity: Using fossil fuels for energy (e.g., coal - fired power plants).
• Replacement: Use solar power (install solar panels for electricity generation). Solar energy production emits far fewer greenhouse gases.

For "Cutting down forests (Deforestation)":

• Original Activity: Clear - cutting forests for agriculture.
• Replacement: Practice reforestation (plant new trees in deforested areas) or sustainable forestry (selective logging). These activities increase carbon sequestration and reduce greenhouse gas emissions from deforestation.
