@inspirgreen: This wood becomes one of the most expensive materials in the world, but only after the tree is infected on purpose. Holes are drilled into Aquilaria trees to introduce fungi, triggering a defense response that produces a dark, aromatic resin inside the wood. Over time, this resin spreads and transforms the inner wood into agarwood, which is used for perfumes, incense, and luxury products. What looks like damaged wood is actually a biological reaction that creates one of the rarest materials on Earth. #nature #Science #trees #biology #wood
