The term renewable and sustainable are very much alike. Sustainable products, like your front lawn, is something that is sustained by mowing it, and it grows back up and you mow it again, much like sustainable forests. You can go in and mow that forest, cut your trees out of there, 10 or 20 years you can come back and do it again.
Renewable, however, as far as your front lawn would go, sustainable, you’re mowing it. If you’re going to renew your front lawn, you’re going to till that lawn under and you’re going to plant a new lawn, therefore, renewing the lawn with a new lawn.
Likewise, with forestry products, if I want to go in and sustain the forest, I go in and keep cutting out of that forest every 10 or 15 years, and that is sustainable. If I want to renew the forest, however, I would go in, most likely cut out more trees, and plant new trees for a later harvest. That would be the difference between renewable and sustainable.
