Most people imagine the sea to be a vast body of water, where humans are (merely) lacking. However, even if human activity is absent, human influence is observable. Carry out 5 minutes of field observation individually. Note down five observations about human use or impact. These can be things or activities that caught your eye, or particular sounds or smell. Fill in your finding in the human use data sheet. (Don’t forget to fill in the location, which in this case is location 1)
