In this video Paul Andersen explains how forests and rangelands are managed to provide renewable lumber and cattle. Threats to renewability of forests include old-growth logging, forest fires, and tree plantations. Threats to renewable rangeland include overgrazing, deforestation, and desertification. Much of the public forests are managed by the USFS and federal rangelands are managed by the BLM. A discussion of the Tragedy of the Commons is also included.
