Can large-scale reforestation mitigate climate change?
Planting trees is one of the most effective ways to mitigate climate change. Trees absorb carbon dioxide from the atmosphere as part of the process of photosynthesis to produce oxygen and store carbon in their wood and roots. This helps to reduce the amount of greenhouse gases in the atmosphere, which is one of the main causes of climate change. A study published in the journal Science in 2019 found that it is possible to restore 1.2 billion hectares of degraded land to forests by 2050. This would sequester an estimated 205 gigatons of carbon dioxide from the atmosphere, which is equivalent to the emissions of 40 years of global transportation. Reforestation is not a silver bullet for climate change, but it is a powerful tool that can help us to reduce greenhouse gas emissions and mitigate the effects of climate change.
