オーストラリア、グレートバリアリーフを救うために空に塩を撃ち放つ可能性を検討【写真】

オーストラリア当局は、同国で最も人気のある観光スポットの一つである世界最大級の珊瑚礁地帯グレートバリアリーフを地球温暖化の影響から救う新たな方法を試すと発表した。デイリー・メール紙が報じた。

報道によると、その結晶が太陽光を反射し、分散させると期待される塩を雲に撃ち放つ可能性が検討されている。

また学者らは、例えば、それでサンゴ礁を覆うよう提案されている生物分解性のソーラースクリーンを使用するなど、サンゴ礁を崩壊させる温度を下げるための様々な方法も検討しているという。

Australia's Great Barrier Reef may never recover from last year's warming-driven coral bleaching, said a study that called for urgent action in the face of ineffective conservation efforts.Record-high temperatures in 2015 and 2016 drove an unprecedented bleaching episode, which occurs when stressed corals expel the algae that live in their tissue and provide them with food.
Bleached coral is more susceptible to disease, and without sufficient time to recover -- which can take one decade or several depending on the species -- it can die.For the new study released late on March 15, 2017, an Australian-led team examined the impact of three major bleaching events -- in 1998, 2002 and 2016 -- over the reef's entire 2,300-kilometre (1,400-mile) length.

UNESCO World Heritage delegates recently snorkelled on Australia’s Great Barrier Reef, thousands of coral reefs, which stretch over 2,000 km off the northeast coast. Surrounded by manta rays, dolphins and reef sharks, their mission was to check the health of the world's largest living ecosystem, which brings in billions of dollars a year in tourism. Some coral has been badly damaged and animal species, including dugong and large green turtles, are threatened. UNESCO will say on Wednesday whether it will place the reef on a list of endangered World Heritage sites, a move the Australian government wants to avoid at all costs, having lobbied hard overseas. Earlier this year, UNESCO said the reef's outlook was "poor".
