The plastic crisis calls on us to rethink the way our society is organised, but is this possible without a fundamental shift in our values?

Event held in French

Plastics now play such a central role in our way of life that questioning their ubiquity also means examining our relationship with living beings and the way we inhabit the world.

During this discussion, philosopher Jean-Philippe Pierron and legal scholar Marine Calmet will share their perspectives on what plastics reveal about our relationship with living beings. They will discuss how the scale of this crisis has been made possible by the invisibility of the fate of non-human living beings. Finally, they will discuss the new ontological connections to be forged with a view to ending the use of plastics, and what philosophy and law can offer each other – and us – in this context.

The discussion will be moderated by Henri Bourgeois Costa, Director of Public Affairs at the Tara Ocean Foundation.

Following the discussion, you will have the opportunity to ask our guests any questions you may have.

About the series ‘Plastics: a systemic poison’

Organised in partnership with the Tara Ocean Foundation, the series ‘Plastics: a systemic poison’ explores a form of pollution that has become a global issue. Since the 1970s, scientific research has revealed the scale of the problem: from the oceans to the mountains, invisible microplastics are entering our bodies and disrupting ecosystems. The humanities and social sciences complement this picture by analysing the economic and social mechanisms underpinning our dependence on plastics.

As the seventh round of negotiations for an international treaty begins this year, these meetings bring together researchers and civil society to pool knowledge and inform public policy decisions. The aim: to collectively rethink our relationship with plastics and the environment.
