Rising sea temperature
Rising sea temperatures have adverse effects on the Great Barrier Reef (Johnson and Marshal 2007). According to Johanna and Marshal (2007), increased temperature has a significant role in destroying aquatic life because sea animals have a particular body heat limit to survive in the ocean. As a result of enhanced heat, this limit has extended beyond that limit (Laugh and Hobdy 2011). For example, 8 years ago summer weather was recorded as the highest temperature in the Australia (GMR Park Authority 2010). Therefore, this process has disturbed the sea mammal’s habitats, also higher temperature leads to shrink the volume of oxygen in the ocean water. To cite an example vulnerable
