Todo lo que nos rodea está hecho con recursos naturales. Algunas cosas son fáciles de reemplazar, mientras que otras no. Piensa en los alimentos que has comido o la energía requerida para acercar al autobús a la escuela. ¿Qué recursos naturales has usado hoy, y estos son fáciles de reemplazar? Adéntrate en la nueva entrega de la serie de libros de comparaciones y contrastes para aprender sobre los recursos del mundo, cuánto tiempo les toma reproducirse y cómo la tecnología y el ingenio están ayudando a calmar la tensión de nuestras reservas más preciadas.
Dog detectives? Thanks to superior sniffers, some pups learn to help scientists investigate and track endangered animals. The snoopers’ clue? Poop. Dogs that are part of wildlife detective teams are trained to catch the scent of wild animal poop (scat) so that scientists can learn about these animals without luring or trapping them. Like many pooper snoopers, Sampson, the dog in this book, was once a shelter dog, too hyper and ball crazy for families. That energy and ball drive is what makes him such a good dog detective. He is trained on many species, from salamanders to bears, but his goal is always the same. Find the scat and get the ball!
Everything around us is made from the Earth. Some things are easily replaced, while others are not. Think about the food you have eaten or the energy it took to zoom to school on the bus. What natural resources have you used today, and are they easy to replace? Step through the latest book in the Compare and Contrast series to learn about the world’s resources, how long they take to reproduce, and how technology and ingenuity are helping to relieve the strain on some of our most precious reserves.
