Plastic bag, water 35 x 30x 5 cm

Years ago I saw a white plastic bag that the wind had blown into the branches of a large tree. It had been halfway filled with water from the rain in which, judging from its colour, a microcosm of organisms had started to develop. A space colony.

Plastic is actually made almost entirely out of oil, which on its part is the result of a few million years lasting compression of remains of prehistoric zooplankton and algae which have been settled to the sea (or lake) bottom in large quantities under anoxic conditions.
