Around 6,000 to 7,000 people demanded measures to protect the climate in a demonstration held in Amsterdam on Sunday, one day before the opening of the United Nations climate change conference in Paris.

The participants took part in a peaceful march from the Museumplein square through the city center and back again. The demonstration was organized by environmental organizations Greenpeace, Milieudefensie and development organization Oxfam Novib.

The demonstrators want people and businesses to use more wind and solar energy and less coal, oil and gas. In addition, they demand more to be done to combat deforestation and to get more money to help people directly affected by the consequences of climate change.

The demonstration on climate change in Amsterdam was one of the many in the world on Sunday. People also took to the streets in London, Berlin, Tokyo, Seoul and Melbourne. The UN climate change conference will open on Monday and run until December 11.
