Protesters hold placards during a "Look up" march, to call on the presidential candidates to take into account the climate emergency, which protesters say is largely absent from the election campaign, less than two weeks after a warning from UN climate experts and a month before the presidential election, in Paris on March 12, 2022. - According to the organisers, nearly 150 marches are expected to take place across France, supported by NGOs, associations or other groups. The protests are dubbed "Look up" in reference to the film "Don't look up", a metaphor for the climate crisis that has been a hit on Netflix.
