For example, the estimated percentage of the global fossil fuel consumption used by each of the world´s 7 billion people as ranked according to the income of each billion shows that the richest use the most environmental resources by far. So education and health for everyone on Earth should be your intention whether you are concerned about the world population or the environment. The sources and data behind the numbers in the film are all referenced here.
