For Earth Day, April 22, France-Amérique turns vert! Speaking of which, did you know the color green was perceived as evil before it was adopted by environmentalists in France and worldwide as a symbol of hope and happiness? The environment is also at the heart of #SaccageParis, a French social media campaign raising awareness on littering, and the work of photographer Ben Thouard, who captures the sheer power of the waves in Tahiti. Also in this issue, read our interview with the former head of U.N. peacekeeping, Jean-Marie Guéhenno, our investigation on the myths and facts of immigration in France – a hot-button issue as we near the presidential election – and our illustrated feature on the Coulée Verte in Paris, the urban park that inspired New York’s High Line!
