Coral rocks face a crisis thanks to a list of growing threats, from climate change to ocean acidification to pollution. In an attempt to stop the tide of damage, the Academy of National Sciences released an important report on Wednesday chronicling the high-tech interventions that we may have to use to save coral.
All the answers are not ready to be ready, but the fact that the first scientific research institution in the United States is talking about is showing the problem's urgency.
"We're losing rocks so fast," says program manager Watch Coral Reef, Mark Eakin Gizmodo. "It's vital that we do everything we can to keep coral rocks alive and healthy."
There are two main coral rescue routes outlined in the report, which commissioned the National Oceanic and Atmospheric Administration (which supervises the Coral Reef Festival). One level focuses on the coral engineering themselves. Research has been taking place ahead of this time for many years, as scientists have tried to unlock the super secrets that can be survived in hot water that cause other coral to die and die, or acidic sea, 39; n abolish rocks.
But the report also calls for more wild interventions, including freezing coral embryos and sperm in an attempt to conserve biodiversity, and pull out in a future climate, hope to cool. The report states that scientists have managed to do this with 16 coral species, but the risks are still high that the frozen process could damage their elegant cells.
The other way to keep a coral is to protect some of their own rocks at a macro scale. That's going into the field of fictional science of geoengineering. Some ideas that have been presented and even have been tested on a small scale include pumping cooler water in depth of the sea, creating artificial shades to cool their own surface water or change seawater chemistry to make it less acidic. The latter contains natural solutions such as plant plant plants as well as more similar ideas such as the sharing of electrochemical calcium carbonate to make the sea more alkaline.
The National Academy's Report is one of the most comprehensive combinations of all the different methods that could help save rocks. A follow-up report will create resources for the realization of some of these ideas in the real world to begin to turn the corral death around the wind.
Coral reefs have fallen by 30-50 percent in all areas of the sea since 1980, a period that has seen three coral world bleaching events driven by hot sea. Those events will become more common only when the planet is heated, meaning that these types of interventions are not just fun.
Literally there is life and death for coral as well as the millions of people who rely on food reefs, protection against storm surges, and their livelihoods. But the interventions are far from the only answers needed to keep rocks around.
"This is not at all to be the place and the efforts that are going to reduce the level of carbon dioxide and other heating gases in the atmosphere," said Eakin. "It is not to replace local action to protect rocks. This is what you do to repair and keep rocks still alive. It's much cheaper and easier to handle & # 39 ; The threats and reduce the chances of harm occurring than rebuilding the ecosystem. "
