When you walk through a forest, you are surrounded by carbon. Every branch and every leaf, every inch of trunk and every tendril of unseen root contains carbon pulled from the atmosphere through photosynthesis. And as long as it stays stored away inside that forest, it's not contributing to the rising concentrations of carbon dioxide that cause climate change. So it's only natural that we might want to use forests' carbon-storage superpower as a potential climate solution in addition to reducing human greenhouse gas emissions.
