S28·E2 The water

In the second episode, the protagonist of the first part of Superquark is water.

Water provides not only drink, but also food: without water, plants cannot grow, and the entire food chain is broken. How long can masks be used? And how are they monitored? Paolo Magliocco and Rossella Li Vigni enter the laboratories that are testing the most commonly used devices during the pandemic, and which will be with us for quite some time to come. Plastic is no longer "forever": Giovanni Carrada and Rossella Li Vigni went to see how new technologies work to recycle previously unrecyclable plastic.
