The planet is in a real emergency situation. A physicist who disseminates science, Jorge Wagensberg, and an economist, promoter of the ecological economy, Joan Martínez Alier, talk about why humanity has caused this threat and how it can act from now on to try to reverse it.

And they conclude that we must introduce the scientific sphere into social and political decisions to preserve the lives of future generations. Claim science against ignorance and expand knowledge in order to collectively make decisions.
