Image captured in January 2020 in one of the Sado estuary Estuary. In the foreground, you can see the oyster nurseries in the middle of the Earth. In the background, the industry in full operation releases to the atmosphere the result of the combustion of its machines. The potential of a river, in this case, the Sado, is enormous, so the need for its balance is fundamental. The image did not undergo any intervention beyond basic adjustments.
