TUCSON, AZ (Tucson News Now) - Every year Earth's trees consume nearly a quarter of the carbon dioxide emitted by people. This in return helps slows climate change and helps keeps the world's temperature from rising a little more each year (Science/AAAS).
Trees store most of the carbon they soak up into their stems and can keep it there for hundreds of years. This service they provide to humanity each year is worth nearly 1 trillion dollars ($1,000,000,000,000) (EPA).
We are now learning that there is no guarantee that trees will continue to do this. Climate change is causing more severe droughts that last longer, this is starting to take a toll on trees and plant life. Larger forest fires are being seen and more insect outbreaks are occurring killing off the trees.
