I have two cutting boards I keep under the sink--one is 1/2 inch thick plastic--rubbery the other is 3/4 inch wood, both are about 30 years old, they last forever. I also have an under the cabinet sliding wood one, which helps with fiber in my diet.
A show (that I detest) was on yesterday. In storm ravaged areas, cut a 1 to 1 and 1/2 inch slab of wood from the top of the stump (a round) of a toppled tree, just ask someone with a chain saw. Leave the bark on it. Let it dry/cure for at least a month. Sand the top and bottom with 100 grit sandpaper and an orbital sander, then with finer grit sandpaper until smooth. Coat with butcher's block oil (found in hardware and big box stores), letting it soak in, reapplying 5 times or so. Very nice to look at and very useable. (Dishwasher safe, probably not.)
