Which of the following can help mitigate the impacts of climate change?

The correct choice, which emphasizes reforestation and afforestation efforts, is crucial for mitigating the impacts of climate change due to their ability to sequester carbon dioxide from the atmosphere. Trees absorb CO2 during photosynthesis, cutting down on greenhouse gas concentrations and thus helping to combat global warming. Moreover, healthy forests can enhance biodiversity, improve soil quality, and regulate water cycles, all contributing to a more resilient ecosystem.

In contrast, increasing fossil fuel consumption contributes to the accumulation of greenhouse gases, which exacerbates climate change. Expanding urban areas can lead to habitat destruction and increased emissions because urbanization often involves more energy use and reduced green spaces. Lastly, reducing reliance on renewable energy sources would limit the transition to cleaner energy options, hindering efforts to decrease carbon emissions and combat climate change. Therefore, reforestation and afforestation stand out as effective strategies for achieving a more sustainable future.
