The Anthropocene refers to the fact that mankind has ended the Holocene and started a new geological age. It is a combination of the Greek “human”(anthropos, άνθρωπος ) and the expression meaning ‘new age’ cene (καινός). Using the word ‘anthropos’ emphasizes that humans are clearly responsible for the changes in Earth’s systems including climate. However, different names for the Anthropocene came from different views of ‘anthropos’. In this study, I examine how the discourse of Anthropocene has influenced ecological art. Ecological arts in the era of the Anthropocene maintain their existing methods, from criticizing the causes of environmental destruction to social practice, discovery of ecological aesthetics, and ecological activism, but they seek a more specifically sustainable ecological future. As examples of ecological art representing the Anthropocene, I study Tara Donovan and Justin Bryce Guaglia, who show the aesthetics of post-nature using plastic; Pina Yoldas, who imagines post-natural lives as no longer natural; Usla Viman and Paulo Tavares, who introduced the activist ecological practices of Ecuadorian indigenous peoples; and Lilian Ball, who executed an ecological art project as a suggestion for a solution. I also examine the work of Soyo Lee, who considers ‘third nature’ through the princess or empress tree(Paulownia tomentosa Steudel).
