Dress-up Sale

To set up a stand, register before 17/11

Conference by the Collectif Pour un réveil écologique: "Facing the climate emergency: from observation to action" 

Wednesday November 29 - 6:30 pm to 8:00 pm - Room 0/86 (N1d)

Is the climate situation really so worrying? 2°C more, what difference does it make? Will science save us?
And what about me? What can I do as an individual? And collectively? What's the point of my studies/job?

In an attempt to provide answers to these questions, a student from the "Pour un Réveil Écologique" collective will give you a brief overview of current socio-ecological issues. He will discuss the rhetoric of inaction and look at ways of taking action on an individual, collective and/or political scale.

Curious, skeptical, convinced... We look forward to seeing you there!
