Do you recognize the different aquatic plants in this house? Our earth consists of 70 percent seas and oceans. In addition to the increase of sea farms that cultivate algae, seaweed and other sea grasses, cities are also giving more and more space to aquatic plants such as reeds and cattails. These wet crops are not only essential for biodiversity and the prevention of harmful subsidence, but can also be used as building material. We show water applications in our house for both outdoor and indoor use.
