Here is my photo @Davide DB mentioned in the start of this thread. In the sea near Oslo, I noticed that i the years after 2013, the marine life dissapeared, the water got darker and the sea floor was covered with sludge. The environment was changing much faster than I thought was possible. In the years to 2012, we had sea ice every winter, which is something I have not seen the last ten years. Before 2012, we were normally preparef for 2 - 0 C watertemperature, while it nowdays seldom get lower than 6C during the winter. Frequent floods, underdimentioned water purification plants and high water temperatures during winter time did something with my local sea and one of the effects is shown in this photo. There are similar problems in th ewhole coastline of Norway, but the impact is lower further north. During this winter, I have several spots to document and compare with images shot at the same spot and date from 2008 - 2013.
