While they are silent and stationary, trees hold tremendous power, including the power to make all our lives better and healthier. Through trees' food-making process, photosynthesis, they absorb carbon dioxide from the air and store it in their wood. Trees and plants will store this carbon dioxide throughout their lives, helping slow the gas buildup in our atmosphere that has been rapidly warming our planet. Older, larger trees store a lot more carbon than young trees, so it's essential that in addition to planting new trees, we conserve and protect the giants of our forests.
