Key Message #1. 9. Ch. 9 | Oceans and Marine Resources. The Nation’s valuable ocean ecosystems are being disrupted by increasing global temperatures through the loss of iconic and highly valued habitats and changes in species composition and food web structure. Ecosystem disruption will intensify as ocean warming, acidification, deoxygenation, and other aspects of climate change increase. In the absence of significant reductions in carbon emissions, transformative impacts on ocean ecosystems cannot be avoided.. One type of animal that made a successful and complete transition from land to water in the course of its evolution is the whale. .. . The According to the fossil record, about 50 million years ago some terrestrial mammals began to make the transition from a life on land to a life in the sea. .
