Mariana lives in sunny Dominican Republic. Even though she is an avid gardener, her new plant no longer produces the berries it once did. With the help of her Tia Leti, an agricultural engineer, she discovers that her plant is not well-matched to its new surroundings and lacks a pollinator. Mariana learns, with her aunt's help, the challenges of maintaining balance in natural systems and the rewards of agricultural engineering. Readers are encouraged to design their own hand pollinators. No se han encontrado descripciones de biblioteca. |
