Nationwide protests across France against government inaction on climate change drew more than 350,000 people across 220 towns and cities on Saturday, organizers said.
The main rally through the center of Paris brought out some 45,000 campaigners, police said, while organizers put the figure at 107,000.
The march coincided with the return of the 'yellow vest' movement, whose so-called ultimatum rally saw violence break out and one of France's richest neighborhoods torched.

The environmental rally, however, was a peaceful affair and saw French movie stars, families, activists and politicians turn out.
Gloomy warnings
Many protesters sang songs and held hands, while others carried signs reading "There is no Planet B" and "Dinosaurs also thought they had time."
Some 45,000 people marched from Paris' famed Opera Garnier to the Republic Plaza
"We are here to demonstrate against the inaction on climate change ... and against the multi-billionaires in their ivory towers," 18-year-old drama student Pierre-Loup Meriaux told the Agence France-Presse news agency.
Dozens of other climate rallies took place across France on Saturday including Lyon, Marseille, and Nantes.
The protests followed the formal launch of legal action this week by Greenpeace, Oxfam and two French environmental groups against the French state over its response to global warming.
The groups launched a campaign called "The Affair of the Century" in December, and have since garnered more than 2 million signatures to an online climate petition.

Students bring grown-ups into line
Protesters in New Zealand invited adults to join the march.
