It is now 2060. Barbara is an engineer working for Superstar's High Tech Shield Center. Her job is to detect and analyze threats to public safety such as floods, earthquakes and even pollution. Thanks to touch detectors embedded in all homes and shackles, Barbara's center can quite predict the potential of natural disasters, determine where it will happen and send rescue teams to Helping people in danger. If warning and support are given in time, people's lives will be well protected.Barbara's husband, Mark, is working for the Ecosystem Infrastructure Network whose primary function is to solve environmental problems to make Superstar City greener, cleaner and more environmentally friendly. Mark and his colleagues are both urban planners. They design and implement projects to reduce fuel consumption, find renewable fuels available for public transport, and promote air-cleaning efforts. Thanks to these projects, the residents of the city mainly use wind and solar energy for cooking, lighting and heating indoors. To ensure there is no shortage of clean water, wastewater is treated and turned into drinking water.Like the residents of Superstar City, Barbara and Mark are delighted with life and work. They only have to work 4 days a week, 4 hours a day. Everyone has more time to learn, entertain and relax. This safe and eco-friendly city is like a paradise for the people who can enjoy the best quality of life.
