(1) Many of the products humans use today have their inspirations in nature. (2) The airplane is a I known example: watching the flight of birds inspired generations of inventors to develop and perfect aviation technology. (3)Similarly, product developers in the adhesive industry (tape, glue, sticky notes are looking to animals for inspiration.
