Environmental experts have worked to calculate the time
necessary for various objects to decompose. Plastic bottles take
450 years to decompose, while glass bottles do not decompose at
all; beer or soft drink cans take 200-250 years, normal tins take
100 years; painted board takes 13 years; canvas products take 1
year; ropes take 3-14 months; cotton fabrics take 1-5 months; and,
train tickets take two weeks.
This study demonstrates that environmental pollution, even of
small objects, will affect many generations to come. Therefore, the
experts appeal to people to consciously build up the environmental
protection awareness, because protecting our earth is everyone’s
responsibility.
