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.
Answer:
The Correct Answer is "C".
Explanation:
Because poor holding communication appropriately place the - SH deposits to frame disulfide spans while expelling the diminishing operator (permitting oxidation) while evacuating the urea. prior to the evacuation of urea, oxidation happens so the cysteine buildups may not be found accurately and the disulfide spans that structure in an inappropriate spots bringing about inert protein
As such, it is a Carcinogen which is basically just a substance that is known to cause cancer.
Hope this helped :)
