Plastic materials dominate the modern world. With science developments in the 19th and 20th centuries, a breakthrough came with synthetic mass-produced plastics. Plastic production has skyrocketed alongside the growing global population. Oil is a basis for hundreds of plastic types and related products, developed through petrochemical processes. Only a small fraction of plastic is recycled (9%), while the rest is discarded after initial use and ends up in the environment. Due to the nature of plastic, it is mostly non biodegradable. Large pieces eventually break down into smaller ones forming so-called microplastic. The accumulation of microplastic in nature has been increasing since the 1950s. This time is considered to be the starting point of the Anthropocene Epoch e a new geological time in Earth history marked by significant human influence on Earth’s natural systems. While some studies indicate that microplastic found in various sediments could serve as a marker for the Anthropocene, other studies tend to disagree with this assertion. Hence, there is currently no scientific consensus on whether plastic can be used as a definitive indicator for the start of the Anthropocene.
