Explores the paradoxical rarity of wood compared to diamonds from a cosmic perspective, asserting that wood is Earth's most precious resource. It highlights that while diamonds are abundant throughout the universe, forming naturally on exoplanets and within meteorites, wood's existence is exclusive to Earth, requiring complex biological processes. The text underscores the immense economic and ecological value of forests, not just for timber but for their crucial role in carbon sequestration, biodiversity, and essential ecosystem services. Furthermore, it emphasizes that wood is a renewable resource driving a sustainable bioeconomy, contrasting it with finite cosmic diamonds and precious metals accessible through asteroid mining. Finally, the source warns of an urgent conservation crisis as forests face significant threats and a large percentage of tree species are at risk of extinction.
