Robert is moving to Arizona. He brought with him a red brome to plant in his new garden to remind him of home. Robert’s new home sits on a plot of land that was once covered with desert brush and many different species of cacti. As he arrives, he notices some lizards scurrying away from his front yard. After Robert unpacks the moving truck, he throws all the boxes and wrapping materials in the garbage. The next day, Robert drives his full-size SUV to his new job at a coal power plant. Robert is excited to start his new life in Arizona. How is Robert affecting his new environment? If Robert continues on his current path, how do you expect the environment will change?
