Ben Nevis walkers have been asked not to throw banana skins on the mountain as they are effectively litter. They have been doing litter picks and banana skins are a real problem for them. Anyway, in the same article they posted how long it takes something to degrade:
- Banana skins/orange peels - two years
- Cigarette butts - 12 years
- Plastic carrier bags - 10 to 1,000 years
- Plastic bottles - 500 years
- Crisp packets - 80 years
- Tissues - A month
