On April 22, Earth Day, science support marches will be held in more than 400 cities around the world.

The initiative emerged in the United States in response to the deep concern of scientists and citizens to the growing wave of anti-scientific policies and erosion of the social image of science. Subsequently, cities around the world have joined the movement. In Spain: Barcelona, Madrid, Seville and Gerona.

The promoters of the March for Science call on citizens to commit themselves to highlighting and sharing the values of science. We want to work to make the practice of research, development and innovation an open and inclusive activity so that science contributes to the greater and better well-being of our society and to ensure that solid evidence, obtained through the scientific method , are the basis for development of policy actions.
