@lynne I vaguely recall someone making the case on twitter or something that you can very plausibly describe wood like it's a science fiction magical material; probably not doing it justice here but:
1. Self-assembling nanomaterial made out of sunlight, air and some dirt.
2. Durable building material, an excellent insulator and extremely easy to work with.
3. Can burn directly for fuel, and the ashes can be used for a bunch of random stuff (making potash, you can write with it, etc). Can also heat it to turn it into charcoal.
4. Can pulp it to make paper.
