In this episode, we’re going to hear about a world identical to ours—politically, climatically, and even biologically—except for one key difference: this is a parallel world that has decided to invest in long-term mobility solutions as a central response to tackling the challenges associated with Climate Change.
So how did it become that way? What were the hurdles – if any – it faced in getting there? And what unexpected social and cultural transformations emerged as a result? Railway engineer and public transport policy activist, Gareth Dennis, guides us through this parallel world.

In this episode, we’re journeying to a parallel world where plastic — once everywhere — is now almost absent from daily life. Single-use plastics, packaging, and synthetic microfibres are no more.

But this isn’t a regression to a pre-industrial past. It’s a world shaped by radical transformations in material culture, in policy, and in collective responsibility.

So how did they get there? Environmental lawyer, activist, and a leader in the fight against plastic pollution, Tiza Mafira, guides us through this parallel world.
