No-one really knows, but estimates suggest 500 to 1000 years.
thousands to millions
No. Roots wrapped in plastic bag cannot absorb water.
Well, technically oxygen molecules do move through a plastic bag, just not fast enough for you to use it in a manner that will help you survive.
The biodegradability of a plastic is not strictly related to its tensile strength.However, it's a fair bet that a biodegradable bag is probably weaker than a "regular plastic" bag.

All i know is that airsoft pellets are made of plastic. Therefore, it would take a very, very, very long time to biodegrade, just like any other solid plastic product. Hope this helped :)
So it can...um, BIODEGRADE PERHAPS?!
A cotton bag will take a few months to biodegrade/decompose.
of course all the time.

There are not any clothes that are made out of plastic. An advantage of having clothes made out of recycled plastic is that it would help the environment. Plastic take many years to biodegrade.
Plastic never biodegrades, it takes forever. If it seems to start biodegrading, its just getting smaller from weather
Foam? Like old coffee cups and such? They never biodegrade. Unlike plastic that will take a thousand years foam will never biodegrade. In ten millions years of something is digging in the ground, it could find your cup that you left behind.
