Forests are the lungs of our planet. Not only do they absorb carbon dioxide and create oxygen, they also regulate temperature, absorb rainwater to help prevent flooding, and provide critical habitat for the majority of the world's land-based plant and animal species.But due to land conversion for agriculture and road construction, timber harvesting, and increasing wildfires, the trees that make up our forests are increasingly endangered. That's why we need reforestation: replanting new forests to replace the old ones.For the past century, the United States Forest Service has helped to replant new forests and manage existing ones. But as scientists face the ongoing threat of climate change, they're developing new strategies... including one that tries to literally predict the future.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
