Coral reef destruction is caused of course by climate change, responsible for our warmer oceans. Corals cannot survive if the water temperature is too high. Higher water temperatures is the main reason behind the death of nearly half of the Great Barrier Reef’s corals.
Urban and industrial waste and oil pollution from shipping are poisoning reefs too – some pollutants, such as sewage and runoff from farming increase the level of nitrogen in seawater, causing an overgrowth of algae, which smothers reefs by cutting off their sunlight.
So A, B and C are the correct answers
The Confederate troops first fired at Fort Sumter in South Carolina. Less than 34 hours later, the union forces had to surrender to them. The reason this firing occurred, was over the debate on slavery. Sectionalism and secession also played part in beginning the civil war.
The correct answer is D. Iraq and Afghanistan.
Explanation
The war in Afghanistan is a military conflict in which the United States fought against the Islamic Emirate of Afghanistan that began in October 2001 and is still active. The main motivation of the United States and its allies to invade this country was the attacks of September 11, 2001. Therefore, the United States promoted an international effort to fight terrorism, which is why it focused on the search for the leader of terrorist Osama bin Laden. On the other hand, there is the Iraq War that originated because the United States accused Iraq of possessing weapons of mass destruction and collaborating with terrorism, participating as accomplices in the attacks of September 11, 2001. According to the above, the correct answer is D. Iraq and Afghanistan.
