Ola Rosling states that he welcomes our criticism and
by Jenna Dodson How much of the planet should we leave for other forms of life? How much of the planet can the 7.6 billion present-day human inhabitants utilize without sacrificing the well-being of future generations? These are important questions with far reaching implications for all species, Homo sapiens included. People are placing unprecedented demands
By Patrícia Dérer Thirty countries around the world have declining human populations. With the exception of Japan, these are European countries that, along with the rest of Europe, have successfully undergone the “demographic transition”. Impressive achievements in health care, education and economic development have resulted in lower child mortality and longer life expectancy, leading to
