There are almost eight billion people alive today. Having that many people in the world puts pressure on both social and natural resources, and we have to ask ourselves difficult questions like, What is our fair share? And how do we share more equitably? Ours to Share starts by giving an overview of human population growth, from the time when there were only a few hundred thousand people until now. The book goes on to examine some of the inequities that happen between people when natural and social resources are stressed and provides examples of people who have found innovative ways to share more equitably with their neighbors. The book also examines the impact our expanding population has had on other species. Finally, the book offers suggestions for actions kids can take to better the world from their own home, school and community.
