This book considers a subject of crucial importance to all, the future of the planet that we live on. As the world's population continues to grow, the ability to sustain and improve the lives of the earth's inhabitants has incurred tremendous costs. Together all must look for ways to sustain the planet going forward while carefully and fairly managing crucial resources and environmental impact of our actions. We asked high school age students from around the world to weigh in on what they see as the planet's opportunities and challenges going forward, offering their solutions on how to best embrace or mitigate what lies ahead. The book considers the next generation's perspective on what science might hold for the planet's future, including examples of how science is already positioned in many instances to enhance and help sustain our world.
