　　大堡礁被誉为“世界七大奇迹之一”。大堡礁本身是几十亿个微小的珊瑚虫组成的巨大生物体，是人类从太空肉眼可分辨的的唯一生命体。
　　大堡礁是地球上最大的珊瑚礁群。它纵贯于澳洲的东北沿海，北从托雷斯海峡，南到南回归线以南，南北跨越2300公里。
　　联合国教科文组织在1981年将大堡礁列为世界自然遗产名录。大堡礁是上千种动物的家园，是地球上物种最丰富、生态环境最多变的地区。大堡礁五颜六色的珊瑚礁，体积巨大，构造复杂，种类繁多，给大量动植物提供了理想的栖息地，包括600多种珊瑚、100多种水母、3000多种贝类、1600多种鱼类、133种鲨鱼和鳐鱼、30多种鲸鱼和海豚。
　　大堡礁虽然是人间仙境，却面临巨大的威胁，包括全球气候变化、酸雨、大面积珊瑚白化、海星过度繁殖等。
　　大堡礁以它未经修饰的自然之美闻名遐迩，也让全世界的游客们趋之若鹜。由于环境原因，大堡礁正在逐年减少，如果你还不曾来到这里一睹它的芳容，请一定将它提上日程，此生去看一次大堡礁吧。

简介：Sir David Attenborough is to present and narrate a new landmark film, Climate Change The Facts for BBC One.　　The documentary will provide an urgent look at the science of climate change and the potential solutions to this global threat, combining footage that reveals the already devastating impact of climate change on our planet with interviews from some of the world’s leading climate scientists.　　After one of the hottest years on record, climatologists and meteorologists explain the effects of climate change on both the human population and the natural world. Scientists, including Dr James Hansen, Dr Michael Mann and Professor Catherine Mitchell will forensically unpack the science behind the extreme weather conditions of recent years, which have seen unprecedented storms and catastrophic wildfires; as well as detailing how the accelerating rate at which the world’s ice is melting is causing sea level rises, and how deforestation is exacerbating the problem of global warming by adding to CO2 in the atmosphere.　　The film will deliver an unflinching exploration of what dangerous levels of climate change could mean for human populations, what is likely to happen if global warming exceeds 1.5 degrees and if major reductions in CO2 emissions are not made in the next decade.　　The documentary looks too at potential solutions, exploring the innovations, technology and actions the world's governments and industries are taking to prevent further warming and showcasing individuals who are creating change at grassroots levels.　　In the film, Sir David Attenborough says In the 20 years since I first started talking about the impact of climate change on our world, conditions have changed far faster than I ever imagined. It may sound frightening but the scientific evidence is that if we have not taken dramatic action within the next decade we could face irreversible damage to the natural world and the collapse of our societies. We're running out of time but there's still hope… I believe that if we better understand the threat we face, the more likely it is that we can avoid such a catastrophic future.”
