Plastic is the material that is probably most representative of our single-use-throw-away culture. When we considering the amount of time that we actively use plastic (as an essential part of electronic devices or as something more simple like a plastic cup) compared to the hundreds of years it takes to decompose plastic, it becomes quite evident what is fundamentally wrong with the way we consume.
In his work Technofossils of the Athnorpocene Dr. Sy Taffel, senior lecturer at Massey University in New Zealand emphasizes: ” …the urgent need for a dramatic reorientation of the material infrastructures and practices of consumption that underpin twenty-first-century digital cultures.” 
How much plastic is becoming part of our future geology is visible in Plastiglomerates. Plastiglomerate, a term just recently coined, refers to polymers that are combined with other materials creating fragments with much greater density. Basically it is a stone made out of a mixture of natural stuff like sand or wood that is held together by a molten and hardened plastic core.
Patricia Corcoran, Charles Moore, and Kelly Jazvac, who discovered and named Plastiglomerates present a striking reminder of the long-lasting and damaging influence of human existence on our environment and a new symbol of the Anthropocene: “…this anthropogenically influenced material has great potential to form a marker horizon of human pollution, signaling the occurrence of the informal Anthropocene epoch.”
