Since civilization, marine animals are forced to adapt their rapidly changing habitat quickly and face many anthropology threats. To start, coral reefs only make up 1% of the ocean footprint yet contribute to more than 25% of all lifes in the ocean. The rising in average sea temperature resulted in devastating coral bleaching events, and some of them will never recover. In addition, various forms of pollution also threatens the life below water, including sound pollution(resulted in the decrease in herring population, which then impacted salmon who feed on herrings andOrcas than feeds off salmons), to plastic pollution(the great pacific garbage patch), chemical pollution (heavy metal, PCBS, radioactive, etc). Furthermore, overfishing and illegal fishing remains a threat to the healthy equilibrium of marine ecosystems. Notably the species that are considered delicacies such as shark fins, abalone, and numerous types of tunas are being overfished the hardest, often from illegal fishing practices due to their high market values.
