L’écologiste N° 49, May-July 2017, 4-page article by Anne Teyssèdre “How to assess our impact on the planet? “, illustrated with photographs of works by Nicole King and Gaspard Noël.
In 1990 ( world population 5.3 billion people ) , P. Ehrlich and J. Holdren developed the first mathematical model *( I.P.A.T.) to calculate to what degree environmental changes were influenced by human activities. Today, 30 years later ( world population 7.8 billion; an increase of 50% ) we speak of our “ecological footprint.”
Anne Teyssèdre
*I.P.A.T. ( I. = Biosphere (living beings together with their environment) = P. (Population) + A. (Average energy resources consumption) + T. (Technology to produce resources).
Five of Nicole King’s paintings were chosen to illustrate the scientific article, including “Turtle and the medusa-plastic bag” seen above.
