From natural sounds to artificial ones and even something in-between — this week's show is all about the indelible link between sound and the environment. We hear how plastic waste can be used to make a new kind of noise, and how kids in Colombia are learning to record animal sounds for conservation. And we meet a Polish composer who has created a unique soundwalk through Berlin's botanic gardens.
