dustan: corals make the frame of the reef. the other animals live in and on that. they're like the trees in a forest; the fish live in the corals much like the birds live in the trees. the corals have specialized fish that live with them, and together they form the community of the coral reef. so we have a co-evolved community that's been doing this for 200 million years. it's like if you go into a small community in new england that's been around for maybe 200 years, everybody's very close-knit. there are all these people that have their little jobs, and they all fit together to make the community work well. so imagine one day when we go into that new england community and we kill the gardeners, and the weeds begin to grow. and then we sort of randomly kidnap people, take away a couple lawyers who take away a couple doctors, we take a few mothers, we take the garbage collector. oh, all of a sudden, the garbage doesn't get collected. pretty soon, that community just falls apart. milner: it's this diversity that's key, that's keeping the reef alive, the reef as a who

come from a special report by the intergovernmental panel on climate change more than half of all coral reefs worldwide are under serious threat. many are dying as a result of mass coral bleaching. without trace the oceans will be empty places. and in addition to the impact on aquatic life humans will be affected too. more than 500000000 people live in low lying coastal areas places that are threatened by a roshon and rising ocean levels coastlines and coral reefs could still be saved provided we take action immediately. next stop the u.s. state of alaska. life look at them for a little while this is now well on trampolines like this you pick people from alaska they threw the hunters in the air and then from up there they look for any mobs. that was possible in a place like alaska where much of the land mass is composed of tundra a type of bio characterized by low growing plants the ground is frozen and covered in snow much of the year. sounds pretty rough it is rough i think but it's the basis for life because when those souls melts actually whole villages collapse and this happens now all a

in fact, according to noaa, healthy coral reefs absorb 97% of a wave's energy, providing significant shoreline protection. unlike concrete and stone sea walls and breakwaters, coral reefs have a tremendous amount of biodiversity that is unparalleled under the surface. they are the rain forest of the ocean. they're essential for tourism industry and for our mishing industry. both recreational and commercial. our coral reefs are suffering right now under the stressors of today's environment and human activity. we need to take steps wherever we can to protect and restore our reefs. i urge support of my amendment and i reserve the balance of my time. the chair: the gentlewoman reserves. for what purpose does the gentleman from utah seek recognition? mr. bishop: i again claim time in opposition. the chair: the gentleman is recognized. mr. bishop: thank you. we once again are on the same situation. this is not a bad idea. it's not a bad concept. in fact, it's such a good concept we're already doing it. so if i quote noaa in their testimony in our committee, the agency currently provides fi

so this is a large—scale coral reef restoration project. the nursery that we use is a rope nursery. lly placed inside a rope and then they are hung mid—water. over half the world's reefs have already been lost because of climate change. coral gets its colour and its energy from the algae which live inside it. as the water gets warmer, though, the algae becomes toxic, so the coral evicts it. this is called bleaching. with its food source expelled, the coral often die. from the nursery, the small coral are brought down and cemented to the ocean floor. within minutes, fish swim to what the reef rescuers call super coral. 0ur coral gardening methodology identifies resilient colonies by visiting reefs shortly after bleaching events and looking at which colonies have survived, and have some level of confidence that they are resilient and will make our restoration site resilient forfurther climate change events. the nursery is also an open water classroom. from the surface, i can see hundreds of coral beneath me. scientists have come from all over the world to learn how it's done here. this

that is what a healthy coral reef sounds like.sts played the sound on loud, under water speakers on dead patches of coral in the great barrier reef. and guess what? they say twice as many fish came and stayed in the places where the sound was playing. the scientists say healthy coral reef is noisy and they look for sounds when they're looking at returning. pretty ingenious. more of that. we need it. thanks for watching this hour. i'll be right back with another hour of news. without the lactose. so you can enjoy it even if you're sensitive. yet some say it isn't real milk. i guess those cows must actually be big dogs. sit! i said sit! mucinex cold & flu all-in-one. fights... oh no. no-no-no. did you really need the caps lock? mucinex cold and flu all-in-one. a lot will happen in your life. wrinkles just won't. neutrogena® rapid wrinkle repair's derm-proven retinol works so fast, it takes only one week to reveal younger looking skin. neutrogena® >>> questions about motive and security. they come in the bake of a deadly shooting on

coral back to life. researchers played recordings from healthy reefs around reefs that were close to dying. ll, they found a 50% increase of marine life. >> trevor: another wait what? ( laughter ) they're using sound recordings from healthy parts of the ocean to inspire sick coral to get better? that is amazing! imagine if you had a sick relative in the hospital you went in with a recording of all her friends having a expaert that helped her get better. "you have ebola, granny? how about now?" what if it turns out all the other negative side effects of climate change could be solved by something this simple. maybe the way to stop cows from farting is to hang out with another cow they have a crush on. "hey, girl. hey, girl." and i know the idea of playing sounds to help heal the ocean sounds ridiculous, but sound is a really powerful tool. i mean, like, think about this-- in the hospital, every time that machine goes beeeeb! the person dies. ( laughter ) they should take that machine up on the of the hospital. it seems dangerous. but let's move on to an international story. kim jong-un is bac

we all know, as go the coral reefs, so go our oceans. these amendments would strengthen federal programs that address the health of our coral reefs. these amendments go to harmful algal bloom, which is a problem throughout our country as well. what can we and should we do about it, as a federally coordinated effort? of course we should do something about that. these amendments would strengthen this bill. these amendments would forward a federal state-partnership -- federal-state partnership, a community partnership to address another armful consequence, which is killing our oceans. -- harmful consequence, which is killing our oceans. these amendments would address coastal resiliency. how do we prevent our ?oastlines from eroding moo my own home state of hawaii -- in my own home state of hawaii, we have seen significant erosion. significant increases in sea level over a very, very recent period of time, that has caused major erosion. how can we adopt better overall programs that adapt to a changing ocean and do not worsen the problem of c

habitats maybe the fish will come back into the environments we would like to try to restore the coral reefers, we played our 2012 recordings, 2014 recordings and when the reef had been healthy. sure enough, we were able to restock these areas with young fish that were coming back from the plankton and by tracking them for six weeks, we found that they stayed there. the community started to rebuild which is exactly what the reef needs to have any chance of recovering. >> do you have a percentage or idea of how much this reef has recovered up to this point? >> so we have just got some photos back. my team around the reef at the moment and we are seeing corals that are back at the size of dinner plates again. these corals are growing quite quickly. what we think by restocking the fish community is that we accelerate that process and ensure that it develops in the right direction, rather than turns into a slime covered or a muddy sea bed bottom. >> how long do you think it will be before you'll see something that reflects what it used to look like? >> yeah. so certainly five good years would m
