so, andy, exactly how big is the great barrier reef? it's immense. he same surface area as germany. 2,300 kilometres in length, thousands of reefs, hundreds of islands, massive. it sounds massive. it must be hard to survey the entire thing, then. they reckon that 40% of the reef hasn't been surveyed. that much? so from a conservation perspective, it's massive. imagine the logistics you would require to do the whole reef, it would be immense. andy is the brains behind earth hour, that 60 minutes every year when businesses and landmarks turn off their lights to raise awareness of climate change. here we are. now, though, he's turned his attention to the reef and is convinced education is the key to its survival. what i'm going to show you now is reef tracks, which is something we've already launched and is starting to show the animals that have got satellite tags that are out on the reef. wow, yeah, yeah. this is a... green turtle? yeah, green turtle, tiger shark, whale shark. this is about to show you a whale shark. this is the first whale shark that's
