Answer:
Human impact on coral reefs is significant. ... Damaging activities include coral mining, pollution (organic and non-organic), overfishing, blast fishing, the digging of canals and access into islands and bays. Other dangers include disease, destructive fishing practices and warming oceans.Factors that affect coral reefs include the ocean's role as a carbon dioxide sink, atmospheric changes, ultraviolet light, ocean acidification, viruses, impacts of dust storms carrying agents to far-flung reefs, pollutants, algal blooms and others. Reefs are threatened well beyond coastal areas. Climate change, such as warming temperatures, causes coral bleaching, which if severe kills the coral.
In 2008, a worldwide study estimated that 19% of the existing area of coral reefs has already been lost, and that a further 17% is likely to be lost over the subsequent 10–20 years.[3] Only 46% of the world's reefs could be currently regarded as in good health [3] and about 60% of the world's reefs may be at risk due to destructive, human-related activities. The threat to the health of reefs is particularly strong in Southeast Asia, where 80% of reefs are endangered. By the 2030s, 90% of reefs are expected to be at risk from both human activities and climate change; by 2050, it is predicted that all coral reefs will be in danger.
Correct answer: C). Making sure that a piece of work is correct and includes bias
The peer review process can be defined as the process of exposing an author's research or ideas or results to be verified by the others who are expert in that field. Its main function is to encourage an author to meet the high standards of discipline in order to ensure that unacceptable results, interpretations or personal views are not published without the expert view.
Any scientific work should not contain any biasness as they may affect the validity of results. Hence, the scientific work does not have any bias.
Hence, the correct answer would be option C.
