Coral reefs provide coastal protection, habitation, and vital economic resources. They are part of stunning aquatic sceneries with millions of plant and animal species. Unfortunately, rising temperatures, pollution, and overfishing are killing the reefs. Attempts to alleviate the consequences of the reefs’ demise with artificial reefs have been unsuccessful due to limitations with cost, eco-friendliness, and effectiveness. My artificial reef design tackles these issues. It is biofriendly: PLA material is the most common home consumer 3D-printing material and is derived from organic sources like cornstarch; low cost: The 400 parts would be crowdsourced using home consumer 3D printers worldwide; and effective: The design would preserve threatened coral species, allow organisms to aggregate, and attract predators to be eradicated like the lionfish.
