Patent Diagrams for Artificial Trees

At least, after we’ve cut down every last tree and forest, once we’ve rid the world of natural species, we’ll know how to build their replacements. Here are some diagrams for artificial trees, signed by their inventors, down to specific tufting techniques and mechanisms for branch attachments. Our future forests will be colorfast and fade-resistant—perhaps machine-washable—filled with recordings of historical birdsong, the world a puzzle we took apart believing someone else would know how to put it back together.
