english: We do this because sunlight acts a bit like tenderizer on a steak, turning the big, tough, durable bonds in PET plastic a bit softer and a bit easier for my bacteria to chew on.
non_english: To radimo zato što sunčeva svetlost deluje donekle kao čekić za meso, tako što velike, čvrste, izdržljive veze u plastici malo omekšava i olakšava mojim bakterijama da je sažvaću.
