Carbon dioxide levels can be reduced in the atmosphere through various measures. Firstly, transitioning to renewable energy sources such as solar and wind can reduce carbon emissions from burning fossil fuels. Secondly, implementing energy efficiency measures in buildings and industries can reduce energy consumption and subsequently lower carbon dioxide emissions. Lastly, afforestation, where trees are planted on a large scale, can absorb carbon dioxide through the process of photosynthesis, helping to mitigate elevated atmospheric levels.
