coral reefs often have trouble regeneratingng in shallow watr bebecause the waves and currens are coconstantly moving the skskeletons of the dead coral around, making it hard for new corals to settle. this has repercussions for the entire ecosystem. sylvanna: mapping the reef, you can see the changes. where you have this long period of time where e the tempmperatus really high and the corals cannot recover, so this has a huge impact on your maririne resource on coral reefs. we have started a coral reef restoration project lookoking t other waysys to try to restore coral reefs s using the corals that are more resilient and growing these corals and putting them back on the reefs. reporter: together with fishers and tourism companies, the country wants to find ys for everyone to use the sea sustainably, even outside thee prottion areas. the marine spatial plan is thee first of i its kind in the indn ocean. sylvannana: i want e everythingt i i do to make a difference andt should have anan impact. i thinink it's a really wonderl feeling knowowing ththat whatr informatation you bring back, is going

bebecause you're not living b by yourself, you're living with 10 other people day in, day out, 24/7, you know? alling: we have inindonesians,se have singapore people, we have europeans, we have americans, plus all the local people from bali we work with. van thillo: we have whale recording system, all our dive setups to dive on coral reefs. studio of the sea is on mir, which is a traveling video studioio that makes educational film. and we can sail everywhere, so it's a perfect platform to study the ocean. dustan: corals, what we think of as stony corals that build reefs, are actually a symbiosis of the animal and a microalgae that lives in its tissues. the animal captures food from the ocean, like plankton, and that supplies nitrogen and phosphorous nutrients. the algae, like a plant, carries out photosynthesis and utilizes those nutrients. when the water gets too hot, the algae are producing so much oxygen because their rate of photosynthesis increases with temperature, that the oxygen they produce is sort of toxic, there's too much, so they become expelled. if the w water gets hot

it's an issue t that we all fac, bebecause we do not give up our consumption of fossil fuels, and...o, where e it's going to o lea? i'm jusust a cowgirl. i don't know. >> after spending some time in this s community,y, i reallyly empathized with their position. first of all, they have a very strongng sense ofof communityty and of place, and i feel, if you are from some of these smaller towns in america where community is so important,, yyou don't want to lose that. you know, people just say, "just pick up and go to a city, like, go somewhere else," and they will say, "no, you know, we love it here. we've been here for generations." i think it started out for me that i thought it would be more of an environmental film, and veryry early on i thought,t, this isis much more a s story abouout rural aameric, and about economy, and how it't's really unfaiair when-- if someone is in a state of desesperation where t they fl that they have to pit jojob agaiainst healthth and enviriro, that's like the expression, you know, being between a rock and a hard place, that's just not a fair place to b

i don't know, bebecause i thik that helping people is a kind of happiness. reporter: those living in caged beds generally pay even more rent for their space than people who live in subsidized flats. if it weren't for lai shan's help, mr. leung and the other men here might not even have warm clothing for the cooler winter nights.s. sometimes, when the people of hong kong come home from work, mr. leung goes to the soccer pitch. he used to work in a slaughterhououse and liveded in employee housing. now he's 70 and in poor health. he's given up hope of ever getting a subsidized apartment, as there are almost 300,000 other people in hong kong who are also on the waiting list. host: now from hong kong, to turkey. two years ago, more than 1000 of the country's academics signed a petition criticizing president recep tayyip erdogan's policies and appealing for an end to his bloody campaign against the kurds -- a small act with major repercussions. many of them were later fired by presidential decree. the accusation -- spreading terrorist propaganda. after the attempt

that, and the rest of us who--"no point in learningng that and no point i n teachching that to you bebecause you're never gonna do that." "you're just gonna be a barista at starbucks." and fofor that, the amount of direction and skills you need are small. i don't mean to pick on starbucks. i enjoy picking on starbucks, but i don't mean to pick on starbucks. ok. what, then, is the solution? well, you can see from the logic of what i've done that it isn't blaming the banker for doing what bankers do, and it isn't blaming workers for doing what they do. workers are told to enjoy the american dream. they are paid until the 1970s-- they're paid more every decade. it's remarkable, the american wage system. a hundred years before the 1970s, wages go up and americans could afford with a rising wage to have a higher standard of living, which is half the reason why millions of immigrants came from all over the world. in the 1970s, as i hope most of you know, real wages stopped rising in the united states and have never resumed. that was, of course, a crisis for the american worker, who had promised to
