After bronze and iron, welcome to the plastic age, say scientists

Plastic pollution has entered the fossil record, research shows

Plastic pollution is being deposited into the fossil record, research has found, with contamination increasing exponentially since 1945.

Scientists suggest the plastic layers could be used to mark the start of the Anthropocene, the proposed geological epoch in which human activities have come to dominate the planet. They say after the bronze and iron ages, the current period may become known as the plastic age.
