Coral reefs may look okay but on closer examination they may be dying. Overfishing, particularly in the Indian Ocean, causes eight steps that lead to reef collapse. Each step is a stage toward the end of a reef. Keeping fish numbers up is important. When the level falls below 1000 kilograms of fish per hectare seaweed growth increases as well as urchin activity. This is a major indication of a problem. If fish density falls below 300 kilograms a crisis is reached. Until now, coral cover has been used as a measure of coral health. This research shows that coral cover is the last threshold: the reef is heading toward ecosystem collapse. It is during the first three stages that constructive change will save a reef. Fishing should be regulated. If a reef is in the final five stages, it is near impossible to save it. Only marine reserves have really healthy coral reefs because fishing is restricted. Unmonitored reefs fare the worst. A management system for each reef needs to be

Many animals have been saved from extinction by captive breeding programs. A creature of the desert, the Arabian oryx, became extinct in the wild in 1972. It has symbolic significance for Arabian people. Individual animals were brought together from Saudi Arabia, Abu Dhabi and Qatar. A watershed occurred in 1982 when some oryx were released into the wild. By 2011 the number of wild oryx reached more than 1,000. The species is no longer endangered. It is now classed as vulnerable. Much has been learned from this successful intervention. This has been done before. In the 19th century the American bison was saved. Today there are 30,000 in the wild and another 30,000 have been bred for meat. In Australia only 50 helmeted honeyeaters were alive in 1990. The Healesville Sanctuary has bred these birds releasing about 20 every year. Australia has adopted a policy of releasing endangered animals onto islands because cats and foxes easily kill native species. The greater stick-nest

Though some scientists still hold onto the "myth" that coastal water will rise only a few centimeters, In a thousand years land area will be much smaller in comparison with the ocean. Some estimates put sea rise as high as 40 meters. This will devastate low-lying land. Countries as we know them today will be unrecognisable. Research is in train to find out sea height 3 million years ago by studying coral reefs, sand dunes and fossils. This will enable more accurate forecasts to be made. The extent of ice sheets that will be left with global warning and higher greenhouse gases will be ascertained. A collection of sediment in the Lamont-Doherty Core Repository, the world's largest, is being used in the study. The frequency of ice ages has already been identified more accurately. They occurred every 41,000 years. It had been believed that the time frame was every 100,000 years. Furthermore, rising mountain ranges cool the Earth's temperature. It is now obvious
