The blue, white and red colors of the French flag that covered the Eiffel Tower after the terrorist attacks of Nov. 13 in Paris are gone.
Green as in trees - stylized, virtual ones, which are being projected on the landmark in honor of the United Nations conference on climate change taking place here over the next two weeks.
A livestream of the appearing and fading trees, which run from 6 p.m. to 1 a.m., Paris time, from now until Friday, can be found on the website of the installation.
The ceremony to kick off the project was attended on Sunday by the secretary general of the United Nations, Ban Ki-moon; Raoni Metuktire, the chief of a Brazilian indigenous group and a vocal advocate for the preservation of the Amazon forest; the French actress Marion Cotillard who is the ambassador for the project, and Nicolas Hulot, an environmental activist and climate adviser for the French presidency.
