In wetlands, the origin of all environments, there is peat, formed one millimeter a year by plant deposition. While looking at the peat, which is the crystallization of irreplaceable time and life, I looked at human activity from the side of nature. Humans took something out of nature and created the landforms of the Anthropocene. The places where peat was dug in the Middle Ages for the coal it produced became lakes. Artificial lakes were built on top of natural lakes for hydropower. The pristine wetland is gradually drying up. I want to capture the shape of time and the peat in the Yoshigadaira wetlands, a 10-year member of the Ramsar Convention, the Broads in Norfolk, UK, which is also a member, and Lake Nozori, a dammed lake in the sky.
