                                Cellulose, the indigestible plant-based fiber that makes up cardboard, is the most abundant organic polymer on Earth. But does that make it safe for human consumption? The short answer is that while accidentally eating cardboard is usually harmless in small amounts, it can pose significant risks depending on the size, amount, and potential contaminants.
