Naturally durable wood is carbon sequestering and 100% biodegradable and can be repurposed, up-cycled, and recycled before reaching the end of its useful service life. The alternatives end their service life in a landfill for an indeterminate amount of time, typically releasing some type of toxin or heavy metal.
Forests regenerate naturally and sustainably when properly managed. If we do not afford value to forest products, what will become of them? They will come under pressure for conversion to non-forest use like ranching, farming, and infrastructure. Substitution of non-forest-based products is the very worst thing for forest preservation.
