Through analysis of historical aerial images, we quantify how much coral reef were lost due to human activity with respect to a baseline level prior to the establishment of the City of Eilat in 1949. Our results show that through construction of infrastructures, human activity has led to the loss of more than 4,810 m2 of coral reef, either directly by the construction or indirectly by changing environmental conditions, which in turn damage the reef.
