The Last for the Sea illustrates a future where humans have contaminated the ocean to the point where sea life is nearly extinct. The last chance to save fish from disappearing forever may be machines developed by engineers and scientists. These machines, which resemble aquatic creatures, can detect and gather waste from the ocean and clean up the sea little by little. One girl’s curiosities led her to learn and appreciate what these robots are doing to aid humankind’s goal of constructing a more promising tomorrow.
