Select an item; compare years to a human lifespan bar.
Lookup persistence in nature; chart compares item lifetime to an ~80-year human span.
Plastic bottle: ≈ 450 years in the environment (illustrative)
Time vs human life expectancy (~80 yr)
Human-readable impact: one lifetime bar is ~80 years; the item bar stretches 5.6× that for Plastic bottle—why “leave no trace” is harder than it sounds.
Decomposition Timeline Lookup helps you select an item; compare years to a human lifespan bar. It is commonly used by engineers, lab users, field operators for how long plastic decomposes, litter decomposition years, banana peel degrade.
Table (illustrative)
- Plastic bottle ~450 years
- Aluminum can ~200 years
- Cigarette butt ~10 years
- Banana peel ~1 month
Real timelines depend on climate, UV, and chemistry; use for education only.
