Question

Read the following passage carecally: In the last decade, the world lost about 14 per cent of its coral reefs, according to a new report. Ocean-acidification, warmer sea temperatures and local stressors such as overfishing, pollution, unsustainable tourism and poor coastal management pose a combined threat to the coral ecosystems, the paper said. The report by Global Coral Reef Monitoring Network (GCRMN) thered by over 100 members of the network covering four decades from 1978 to 2019. It had almost 2 million observations from more than 12,000 sites in 73 reef-bearing drawn from a global dataset countries across the globe. The report, the first of its kind in 13 years, underlined the catastrophic consequences of global warming but said that some coral reefs can be saved by arresting greenhouse gases Coral reefs across the world are under relentless stress from warming caused by climate change. Coral bleaching events caused by rise in elevated sea surface temperatures (SST) were responsible for coral loss, according to the report. 4 Large scale coral bleaching events were responsible, for killing eight percent of the world's corals in 1998. This is equivalent to more than the coral that is currently living on reefs in the Caribbean or Red Sea and Gulf of Aden regions There has been a steady decrease in hard coral cover in the last four decades since 1978 when the world lost nine per cent of its coralsala The worst-hit are the corals in South Asia, Australia, the Pacific, East Asia, the Western Indian Ocean and the Gulf of Oman. The decrease is disconcerting because live hard coral cover is an indicator of coral reef health.
On the basis of the reading of your passage, answer the following questions:
1. The world has lost 14 percent of its coral reef. How many years did it take to happen?
2. Various conditions are responsible for the erosion of the coral ecosystems. What are they?
3. How can we minimize the disastrous effect of global warming on coral reefs?
4. What is responsible for coral bleaching event?
5. "The worst-hit are the corals in South Asia, Australia, the Pacific, East Asia, the Western Indian Ocean and the Gulf of Oman." What problem have these parts of the world faced?
6. Find a word from the passage which is the synonym of 'DISTURBING'.​

Answer:

mystery, style, conflict, character find the odd element

Answer 2

Answer:

1)Recent studies have revealed that 50% of the world's coral reefs have already been destroyed, and another 40% could be lost over the next 30 years.

2)Pollution, overfishing, destructive fishing practices using dynamite or cyanide, collecting live corals for the aquarium market, mining coral for building materials, and a warming climate are some of the many ways that people damage reefs all around the world every day.
