0:00:05 > 0:00:09Hidden in the heart of Borneo is a lost world of jungles,
0:00:09 > 0:00:12mountains and ravines.
0:00:12 > 0:00:16This rainforest is home to thousands of endangered animals,
0:00:16 > 0:00:19but it's disappearing fast.
0:00:19 > 0:00:24For the past four weeks, some of the world's most experienced scientists,
0:00:24 > 0:00:30mountaineers and filmmakers have been charting this great unknown wilderness.
0:00:35 > 0:00:40In the first phase, the expedition explored the virgin forests
0:00:40 > 0:00:44of Imbak Canyon and discovered some extraordinary animals.
0:00:44 > 0:00:47- Stunning!- Oh, what's that on the wall? Oh, look at that!
0:00:50 > 0:00:53Now it's splitting into two teams
0:00:53 > 0:00:57to venture even further into the mountains.
0:01:11 > 0:01:16To find your way through this impenetrable jungle, it helps to take to the air.
0:01:24 > 0:01:29Climber Steve Backshall is on an aerial recce for his next mission.
0:01:32 > 0:01:38I tell you what - getting anywhere through this scenery is going to take forever! It looks brutal.
0:01:38 > 0:01:43Really sharp limestone pinnacles through almost impenetrable jungle.
0:01:43 > 0:01:49Steve's plan is to lead a team to an unexplored part of the Mulu mountains.
0:01:49 > 0:01:51What's that?
0:01:53 > 0:01:56Can you just head a little bit east?
0:01:56 > 0:02:01It looks like there's a massive sink hole.
0:02:01 > 0:02:07It's an underground cave where the roof collapses and just forms a vertical hole straight down.
0:02:07 > 0:02:09It's exactly what we've been looking for -
0:02:09 > 0:02:14a whole environment totally shut off from the rest of the world, we've got to get in there!
0:02:15 > 0:02:19Steve's goal - to explore the forest in the depths of this giant sinkhole.
0:02:27 > 0:02:31Expedition Borneo's second team is heading south,
0:02:31 > 0:02:35led by environmental scientist Dr Tara Shine.
0:02:35 > 0:02:38So maybe you can show me where we're going to go?
0:02:38 > 0:02:41She's heading to an area, not yet protected,
0:02:41 > 0:02:45- but apparently rich in wildlife. - Here is Bungalun.
0:02:45 > 0:02:49Her ultimate destination - an extraordinary cave
0:02:49 > 0:02:54in the Marang mountains, home to an ancient culture.
0:02:57 > 0:03:01To reach her goal, Tara will travel for three days up the Bungalun river.
0:03:01 > 0:03:05A chance to assess the state of the forest in this area.
0:03:05 > 0:03:08- Yeah.- Fish eagle.- Yeah.
0:03:10 > 0:03:14There's proboscis monkeys just in here behind the big tree trunk.
0:03:19 > 0:03:21Oh, they're amazing jumpers!
0:03:21 > 0:03:24They can jump clear across rivers if they want to.
0:03:26 > 0:03:29Oh, it's launched! Wow! SHE LAUGHS
0:03:33 > 0:03:39All seems well, but as Tara rounds a bend in the river, everything changes.
0:03:39 > 0:03:42Much of the forest has been destroyed.
0:03:42 > 0:03:46These whitened tree trunks are the scorched remains
0:03:46 > 0:03:49of the biggest forest fires the world has ever seen.
0:03:49 > 0:03:53This is amazing up here, all these skeleton trees.
0:03:53 > 0:03:57This forest would have been burnt out in the last big fires of '97
0:03:57 > 0:04:02and then at the lower level they're kind of... The bushes have started to grow back.
0:04:02 > 0:04:07Over the last two decades fires have ravaged this region.
0:04:07 > 0:04:12As the flames died down, gangs moved in to plunder the remaining trees.
0:04:12 > 0:04:15It's a free for all.
0:04:15 > 0:04:20These are the illegal loggers that operate in the area, they stick mainly to the rivers.
0:04:20 > 0:04:23So they go into the forest, cut down timber illegally
0:04:23 > 0:04:27and then they float it down the river behind these boats.
0:04:27 > 0:04:31It's a bit like a camel caravan - they just tie all the boats together
0:04:31 > 0:04:35and then link them together with all of the wood that they've collected.
0:04:39 > 0:04:43This is ironwood, one of the most valuable and most tough woods
0:04:43 > 0:04:47that grows in Borneo, and here they've actually milled the wood into planks.
0:04:50 > 0:04:55As the timber is floated downstream to the markets of the world,
0:04:55 > 0:04:59the river itself is thick and brown with the soil washed out from the jungle.
0:05:06 > 0:05:09All over Borneo, the remaining forest is under threat.
0:05:11 > 0:05:16But now at the 11th hour there's a plan to save it.
0:05:16 > 0:05:20The ambitious goal is to join together a patchwork of reserves
0:05:20 > 0:05:23to create one giant protected forest,
0:05:23 > 0:05:25the Heart of Borneo.
0:05:28 > 0:05:33This sinkhole is in Mulu - one of the protected areas.
0:05:36 > 0:05:41It's here that Steve Backshall and climbing camerawoman Justine Evans are headed.
0:05:44 > 0:05:48They'll journey through a wilderness of mountains and caves.
0:05:57 > 0:06:01The team make camp at the foot of the mountain.
0:06:02 > 0:06:07While climbing specialist Tim Fogg prepares the equipment,
0:06:07 > 0:06:12Justine and Steve will spend a day exploring nearby caves for wildlife.
0:06:12 > 0:06:17I'm not into furry, cuddly stuff, I'm more into the kind of things that most people hate.
0:06:17 > 0:06:20If it's slimy, or has loads of legs, I'm happy!
0:06:20 > 0:06:24And I think there's lots of that sort of stuff around, so for me this place is paradise.
0:06:26 > 0:06:31Steve heads off in search of his favourite animals - snakes.
0:06:31 > 0:06:37Justine has a personal goal, to film one of Borneo's greatest wildlife spectacles.
0:06:37 > 0:06:41She's heading for one of the biggest caves in the world.
0:06:41 > 0:06:44Wow! It's huge!
0:06:44 > 0:06:46Absolutely huge!
0:06:47 > 0:06:51That is so much bigger than I thought it was going to be.
0:06:51 > 0:06:55This whole mountain is like a Swiss cheese, it's just full of holes.
0:06:55 > 0:06:57And these passages just lead into...
0:06:57 > 0:07:00Well, no-one really knows where they lead, but they all connect up
0:07:00 > 0:07:05in this incredible labyrinth that goes throughout the mountain.
0:07:05 > 0:07:12This cave is 100 metres high and two kilometres long.
0:07:12 > 0:07:15Wow, there's an absolutely amazing view!
0:07:15 > 0:07:19And it's also home to over three million bats.
0:07:19 > 0:07:24At dusk, Justine's hoping to capture their mass exodus on film.
0:07:24 > 0:07:29But they'll only fly if the weather's right.
0:07:29 > 0:07:32We've actually got some blue sky as well, this is a real treat.
0:07:32 > 0:07:36We'd better get this camera set up quite quickly and then...
0:07:36 > 0:07:39And then we'll film the bats, hopefully, as they come out.
0:07:46 > 0:07:52Steve's exploring a nearby cave with Mutan - his tribe have lived in this forest for generations.
0:07:55 > 0:07:57He's looking for snakes.
0:07:59 > 0:08:04Oh, wow! Oh, crumbs, I wasn't expecting that!
0:08:13 > 0:08:17So these are very obviously ironwood coffins, traditional coffins.
0:08:17 > 0:08:22These pots were for water, for cooking and for food.
0:08:22 > 0:08:27I presume it's like an offering, either to the spirits or to the ancestors themselves.
0:08:27 > 0:08:33The reason everything's broken is because animals have smelt the remains of the dead people
0:08:33 > 0:08:38and they've come up here and smashed into the vases to feed on the remains.
0:08:38 > 0:08:42Amongst the pottery lie the disturbing remnants of Mutan's ancestors.
0:08:45 > 0:08:49SPEAKS LOCAL LANGUAGE
0:08:49 > 0:08:53OK, so all this stuff was here before his father and his grandfather
0:08:53 > 0:08:55so it's been here for you know a couple of generations.
0:08:55 > 0:08:56So we're talk...
0:08:56 > 0:08:59THEY CONVERSE IN LOCAL LANGUAGE
0:08:59 > 0:09:02..So certainly over a hundred years. It's all been here.
0:09:03 > 0:09:06These remains are one of the few signs
0:09:06 > 0:09:11that tribal people have for centuries lived and died in these forests.
0:09:18 > 0:09:23500 kilometres away, the effect of modern humans is all too apparent.
0:09:26 > 0:09:32Look at the size of these big logs here, waiting to be taken away with those strings on them.
0:09:33 > 0:09:38On the river bank, shantytowns have built up around the illegal logging trade.
0:09:44 > 0:09:48This is one of those frontier towns, that's just all about logging.
0:09:48 > 0:09:53So it sprung up after the big fires that hit Kalimantan in 1997
0:09:53 > 0:09:55and really completely destroyed this area,
0:09:55 > 0:09:58which meant then that illegal loggers could move in
0:09:58 > 0:10:01and more easily pick their way through what was left of the forest,
0:10:01 > 0:10:06take out big trees to sell illegally downstream, so it's a bit of a Wild West town.
0:10:06 > 0:10:10CHICKEN CLUCKS
0:10:10 > 0:10:16There are a still a few people that knew this place when it was pristine rainforest.
0:10:16 > 0:10:20Semen and Busa have lived in this valley all their lives.
0:10:23 > 0:10:26When I was coming in here I noticed that,
0:10:26 > 0:10:28compared to the other forests I've seen in Borneo,
0:10:28 > 0:10:31there aren't very many big trees here, was it always like that?
0:10:31 > 0:10:34INTERPRETER:
0:10:36 > 0:10:41Here do you still find many sambar deer and barking deer and wild boar?
0:10:47 > 0:10:51So could tell me what kind of animals I could expect to see in this area?
0:10:57 > 0:11:00There's one particular animal that used to be common in this forest.
0:11:07 > 0:11:10When Semen was younger, animals were plentiful
0:11:10 > 0:11:13and he made his living from the forest as a hunter-gatherer.
0:11:13 > 0:11:16But living close to nature had its dangers.
0:11:26 > 0:11:28So crocodiles have eaten his mother
0:11:28 > 0:11:32and they also attacked his brother and his brother subsequently died.
0:11:32 > 0:11:35If you did find a crocodile what's the best weapon to use?
0:11:37 > 0:11:40TARA: Could I see his blowpipe?
0:11:42 > 0:11:46Felt like a very strange thing to say to a man - can I see your blowpipe?!
0:11:52 > 0:11:53Woooah!
0:11:57 > 0:12:00- What noise do I have to make again? - Puff!
0:12:00 > 0:12:05All right. Can I have a go? Watch out, the whole village!
0:12:09 > 0:12:13Did I get it further than he got it? Oh, I got further than you!
0:12:15 > 0:12:16Ah, he's...
0:12:17 > 0:12:21Well, even if he's being reluctant with the praise, she says I did a good shot.
0:12:26 > 0:12:33Back in Mulu, Steve ventures deeper into his cave in search of snakes.
0:12:33 > 0:12:37It's a world of strange creatures adapted to life in complete darkness.
0:12:44 > 0:12:47This is the biggest spider I've seen on this trip.
0:12:47 > 0:12:50It's a huntsman
0:12:50 > 0:12:52and, a lot of spider venoms
0:12:52 > 0:12:56have what are known as necrotising enzymes in them.
0:12:56 > 0:13:01Which means they literally liquefy or rot living flesh
0:13:01 > 0:13:03and nobody wants a bite like that.
0:13:03 > 0:13:05So I think I'll leave him well alone.
0:13:08 > 0:13:13Steve pushes even further into the bowels of the Earth in pursuit of snakes.
0:13:16 > 0:13:20You get loads of different kinds of snakes coming into caves,
0:13:20 > 0:13:23and the reason for that is bats.
0:13:23 > 0:13:27I think bats are just a fantastic prey for snakes.
0:13:37 > 0:13:38Bingo!
0:13:38 > 0:13:43There's our first snake, look at that!
0:13:43 > 0:13:46This is a cave racer snake.
0:13:46 > 0:13:50The way that you most often see snakes catching bats in caves
0:13:50 > 0:13:53is they'll coil themselves in an alcove
0:13:53 > 0:13:57and will quickly straighten and snatch the bat from the sky.
0:13:57 > 0:14:01Oh, and here's another one, and the one that's up here,
0:14:01 > 0:14:06is at the absolute perfect height. It's right on the flight path.
0:14:06 > 0:14:09You see the tongue flicking in and out tasting the air,
0:14:09 > 0:14:14and the way that he's sitting he is in the perfect position for hunting.
0:14:14 > 0:14:15This one is looking for a meal.
0:14:15 > 0:14:19And do you know, he is poised, so today could be the day.
0:14:27 > 0:14:32Justine's still waiting patiently to film her bats
0:14:32 > 0:14:34in a cave that reeks of their guano.
0:14:34 > 0:14:36But there's no sign of them.
0:14:39 > 0:14:43Apparently there are three million bats in here. And I've seen one.
0:15:02 > 0:15:05Wow, we've got some luck, they're starting to come out!
0:15:10 > 0:15:14I was just packing up, and then we heard...
0:15:14 > 0:15:17the vocalisation of them in the cave.
0:15:17 > 0:15:20And now they've started pouring out,
0:15:20 > 0:15:23they're right at the top of the entrance here.
0:15:23 > 0:15:26That's great, it's good to see them.
0:15:27 > 0:15:31In just one night, these bats can travel 40 kilometres
0:15:31 > 0:15:34and eat ten tonnes of insects.
0:15:37 > 0:15:40There's a ball of them just headed off.
0:15:41 > 0:15:44A splinter group, just gone off down there!
0:15:51 > 0:15:53Three million bats!
0:15:54 > 0:15:57Unbelievable!
0:16:01 > 0:16:06This number of bats is a clear sign of the health of this protected forest.
0:16:13 > 0:16:18The next morning, the other team continues towards the Marang mountains.
0:16:18 > 0:16:23The further Tara goes, the stranger this place becomes.
0:16:29 > 0:16:32After so much deforestation,
0:16:32 > 0:16:35it's encouraging to see there's still wildlife.
0:16:35 > 0:16:38See here?
0:16:38 > 0:16:43It's a huge big monitor lizard, that's two-and-a-half metres long, huge big guy, big powerful jaws.
0:16:48 > 0:16:51Oh, it's gonna take off - they're real skittish.
0:16:54 > 0:16:57They're entering a forbidding landscape riddled with caves.
0:16:57 > 0:17:01Even here there are signs of people.
0:17:02 > 0:17:05It's not timber that's brought them here.
0:17:05 > 0:17:12They're searching for an even more valuable treasure that lies deep within these mountains.
0:17:12 > 0:17:15This cave is defended like a fortress.
0:17:19 > 0:17:24This is what they're protecting - swiftlet nests.
0:17:24 > 0:17:27For centuries they've been collected to make birds' nest soup.
0:17:27 > 0:17:30This nest is worth as much as £20.
0:17:32 > 0:17:35Wow! Look at this - Fort Knox.
0:17:35 > 0:17:37For this business to be successful,
0:17:37 > 0:17:40there has to be a healthy population of swiftlets.
0:17:47 > 0:17:49It's like living in a cathedral.
0:17:49 > 0:17:55Slightly smelly cathedral though, cos the flooring is pure bat excrement.
0:17:56 > 0:18:00These men guard the cave 24 hours a day.
0:18:00 > 0:18:01Do they also collect the nests,
0:18:01 > 0:18:05or are there other people to collect the nests?
0:18:10 > 0:18:12No wonder he's all muscles!
0:18:12 > 0:18:16Imis shows Tara the tools of his trade.
0:18:16 > 0:18:20What's he getting? Oh, this is his climbing bamboo.
0:18:20 > 0:18:23The job of a bird's nest collector is a dangerous one.
0:18:25 > 0:18:28Broken limbs are all too common.
0:18:30 > 0:18:33My God, what a technique!
0:18:33 > 0:18:37It must be slippy over there, it's quite wet, isn't it?
0:18:37 > 0:18:39Maybe he's got superglue feet.
0:18:40 > 0:18:43The nests are in the highest part of the cave.
0:18:43 > 0:18:48It's dangerous work, but good money - for some.
0:18:48 > 0:18:52They get 13,000 US a year.
0:18:52 > 0:18:5513,000 US dollars a year? That's a lot of money.
0:18:55 > 0:19:01I mean these guys don't get to keep all that money, it's his boss who's getting the big profit.
0:19:01 > 0:19:02Exactly.
0:19:02 > 0:19:04It's big business.
0:19:04 > 0:19:09Here there are no quotas, and the nests are over-collected.
0:19:09 > 0:19:13This old man worked these caves years ago.
0:19:13 > 0:19:16How much bird's nest was he collecting?
0:19:16 > 0:19:20Be interesting just to see if it was more or less than is available now.
0:19:24 > 0:19:28And now Imis is only getting half a kilo in the same period?
0:19:28 > 0:19:33Since the old man's time, two thirds of the birds have gone.
0:19:34 > 0:19:39At this rate, the birds and the livelihood could soon disappear.
0:19:43 > 0:19:48Mountains and caves straddle the backbone of Borneo.
0:19:48 > 0:19:53Some have been exploited, some lie totally unexplored.
0:19:55 > 0:19:58No-one knows what's hidden at the bottom of this hole.
0:20:02 > 0:20:07Justine and Steve have begun their gruelling ascent in the stifling heat.
0:20:11 > 0:20:16The terrain is treacherous - steep and very slippery.
0:20:20 > 0:20:23The rocks - razor sharp.
0:20:26 > 0:20:29Don't be kicking any of that down on my head!
0:20:32 > 0:20:36- But after a punishing climb, they make it to the edge.- Oh, my God!
0:20:39 > 0:20:41That is a big hole!
0:20:44 > 0:20:47That is a very, very long way down.
0:20:47 > 0:20:52They stand on just a thin overhang of soil and roots.
0:20:52 > 0:20:56It's a 160-metre drop below.
0:21:00 > 0:21:05- Be careful, Justine, that edge there is very, very dicey, - There's nothing there, really.
0:21:05 > 0:21:09No, this is all overhung as well, that just drops straight down beneath our feet.
0:21:09 > 0:21:13It's too late to begin the descent, so they make camp on the edge of the hole.
0:21:15 > 0:21:18Tomorrow, they will venture into the void.
0:21:25 > 0:21:29Tara is nearing her goal in the Marang mountains.
0:21:31 > 0:21:35Halfway up the cliff is this amazing cave -
0:21:35 > 0:21:38home to an ancient culture.
0:21:38 > 0:21:43It looks very steep. Such a dramatic bit of rock, isn't it?
0:21:43 > 0:21:46This is Tara's ultimate destination.
0:21:48 > 0:21:51I have no idea what's ahead of me.
0:21:54 > 0:21:58Team member Luc-Henri Fage, an expert on these caves,
0:21:58 > 0:22:01helps Tara negotiate the cliff face.
0:22:01 > 0:22:04There's nothing to hold on to.
0:22:04 > 0:22:06I'm holding to anything that...
0:22:10 > 0:22:15- Right, so I'm going up here. - Yeah. OK?
0:22:18 > 0:22:20Very good, very good!
0:22:21 > 0:22:25Only recently discovered by this bird's nest collector,
0:22:25 > 0:22:29this cave contains one of the most incredible examples
0:22:29 > 0:22:32of prehistoric rock art in the world.
0:22:32 > 0:22:34Oh, wow - look up here!
0:22:45 > 0:22:50These hands were painted by forest people 10,000 years ago.
0:22:54 > 0:22:57The paintings are extraordinary.
0:22:57 > 0:23:00- You can see 200 hand prints. - There's 200 hand prints in here?!
0:23:00 > 0:23:01On that...on that level.
0:23:01 > 0:23:04Do you paint over your hand or, how do you do it?
0:23:04 > 0:23:09They put their hand on the wall and they spray colour,
0:23:09 > 0:23:11probably it was in the mouth.
0:23:11 > 0:23:12Like this.
0:23:15 > 0:23:20The meanings behind these pictures are as unknown as the artists that painted them.
0:23:22 > 0:23:25But they're proof that people have lived in this forest for millennia.
0:23:25 > 0:23:28And they left nothing behind but their art.
0:23:31 > 0:23:35Isn't that incredible to think they've existed here so long?
0:23:35 > 0:23:37Why? Why here?
0:23:37 > 0:23:40Why they did that is still a mystery.
0:23:44 > 0:23:47Tara and the team have made camp on the edge of the cave,
0:23:47 > 0:23:50named Gua Tewet after the man that discovered it.
0:23:52 > 0:23:55What's his impressions of these paintings?
0:23:55 > 0:23:56What does he think they're all about?
0:23:56 > 0:23:59INTERPRETER ASKS QUESTION
0:24:10 > 0:24:11And what about the hands, then?
0:24:17 > 0:24:19Yeah.
0:24:33 > 0:24:36It's dawn in the Marang mountains.
0:24:36 > 0:24:39Most of the team is sound asleep in the cave.
0:24:39 > 0:24:43But Tara has woken to a forest under siege.
0:24:44 > 0:24:46SOUND OF CHAINSAW
0:24:46 > 0:24:50I woke up this morning in this beautiful cave,
0:24:50 > 0:24:52to the distant sounds of chainsaws.
0:24:55 > 0:24:59Now, gradually, the trees are starting to emerge from the mist.
0:24:59 > 0:25:02BIRDS AND ANIMALS CALL
0:25:03 > 0:25:07And the gibbons have started up over here somewhere,
0:25:07 > 0:25:11there's a pair duetting over there - it's lovely to listen to.
0:25:16 > 0:25:20To the right - forest.
0:25:20 > 0:25:21To the left - deforestation.
0:25:23 > 0:25:26This cave was once in deep jungle.
0:25:26 > 0:25:29Now, it's on the frontline.
0:25:30 > 0:25:33I was just thinking about... it doesn't seem right
0:25:33 > 0:25:38to be listening to chainsaws and gibbons at the same time.
0:25:38 > 0:25:41I mean, this is such a beautiful serene landscape
0:25:41 > 0:25:45and the bird noises and the gibbon sounds and the macaques over here,
0:25:45 > 0:25:47that all fits into what you would expect.
0:25:47 > 0:25:51But the roaring chainsaw's a backdrop to all of that.
0:25:51 > 0:25:54Makes you worried that this area could really be decimated.
0:25:57 > 0:26:02Conservationists have proposed this area as a World Heritage Site.
0:26:02 > 0:26:07But the danger is, it may be destroyed before it can be protected.
0:26:17 > 0:26:20On the rim of the giant chasm, the tension is mounting.
0:26:22 > 0:26:25The kit is checked
0:26:25 > 0:26:27and checked again.
0:26:27 > 0:26:29There's no room for error.
0:26:31 > 0:26:37With the help of climbing specialist Tim Fogg, they prepare for their daring descent.
0:26:37 > 0:26:42There's a 160 metres of rope hanging down there, and that's heavy.
0:26:42 > 0:26:46That's going to make your descent slow. You have to lift and it can be hard work.
0:26:46 > 0:26:50Below them lies a forest cut off from the rest of the world.
0:26:50 > 0:26:53No-one knows what life exists there.
0:27:02 > 0:27:06Steve pushes through the tangled vegetation...
0:27:06 > 0:27:08and over the edge.
0:27:09 > 0:27:15Only when he clears the overhang can he see the true scale of this collapsed cave.
0:27:19 > 0:27:22The under hang here is just immense!
0:27:30 > 0:27:32- OK, Justine!- God!
0:27:32 > 0:27:35If you're feeling brave, give it a go!
0:27:35 > 0:27:36Feeling VERY brave!
0:27:42 > 0:27:43Oh, my God!
0:27:43 > 0:27:46Steve, it's amazing!
0:27:46 > 0:27:48Are you getting vertigo? Cos I am!
0:27:48 > 0:27:51My heart is still right up in my throat though, I've gotta say.
0:27:51 > 0:27:56- Have you ever been exposed like this on a rope before?- No.
0:27:56 > 0:27:59I just want to hold on to something, you know?
0:28:03 > 0:28:05But as they abseil into the chasm,
0:28:05 > 0:28:08the weather suddenly takes a turn for the worse.
0:28:09 > 0:28:12A tropical storm is blowing in.
0:28:12 > 0:28:16Any minute now it will be directly over them.
0:28:23 > 0:28:26Justine don't...don't come down here just yet.
0:28:26 > 0:28:28Stay where you are for a second.
0:28:33 > 0:28:36THUNDER CRASHES
0:28:37 > 0:28:42They must decide - do they struggle back up the rain-soaked ropes?
0:28:42 > 0:28:45Or continue down into the unknown?
0:28:51 > 0:28:53This is terrifying!
