exist are out of the ground and they're in the treetops. this is the symphony section of the experience. >> reporter: the cicadas are now letting thehemselves be heard. >> that's loud. >> yes. >> reporter: dr. bug says it's just the males making all that noise, at levels that rival a garbage disposal or vacuum ceaner. >> about 72 decibels. >> reporter: they are trying to attract female cicadas, which have notoriously high standards. >> they get the chance to sit around and say mm, i don't like him, i don't like him, i don't like him. that one, i like him. >> reporter: for the next four weeks the cicadas will fulfill their 17-year mission, mating in the trees to produce the next generation while trying to avoid getting eaten by a bird before they do it. >> truly a majestic existence. >> are you sure you're a scientist with the usda? >> reporter: dr. bugs isn't the only one enjoying cicada mania. these odd-looking insects are inspiring art, fashion, and music. ♪

♪ cicada ♪ a brewery in virginia create aid cicada beer and named it brewd x. >> no cicadas were hurt in the making of this beer. >> which is perfect for crunching down a cicada taco. you'd expect the guy wearing this to enjoy eating that. but at this restaurant in leesburg, virginia they're selling 30 orders of cicada tacos every day. >> about 50% of those that come in order a second round of tacos. >> reporter: tobias potavano is the chef. >> those look tasty. i do see little cicada eyes looking at me. >> yeah. they're going to look at you. they'll judge you. >> then it was time for my first -- >> bon appetit. >> -- bug bite. >> crunchy, nutty. so our anchor gayle king really wants to eat some cicadas. could you send her a a couple o these? >> most definitely. >> reprter: unfortunately, after waiting 17 years the cicadas' moment of glory is fleeting. >> they are here for a good time, not a long time. >> reporter: dr. bugs says both

the males and the females will die off after mating. the eggs the females lay in the trees will fall to the ground and the 17-year cycle starts all over. >> are you going to be sad to see them go? >> ben, i cannot describe to you just the sense of dread that is already in my heart knowing that i am not going to be able to experience this again until i am in my 40s. >> that's perspective. >> reporter: so we soon say farewell to brood x. we'll see you in 2038. ben tracy, washington. noisy cicadas aren't the only creatures looking to spawn this spring. there's also salmon. the trouble is a prolonged drought in the western states is threatening their survival. biologists and truckers are now joining forces to help save the species. jonathan vigliotti shows us how. >> reporter: captain sarah bates has been reeling in salmon off the california coast for nearly a decade. >> catching fish never gets old. you know, it doesn't really matter how many times you've

done it. even when you're catching 100 fish a day or more, it's still fun every time. >> bigger fish. >> reporter: commercial and recreational salmon fishing generates more than $900 million annually for california. but with much of the state in a punishing drought the fishing industry is feeling the stress. >> nobody can survive an entire season that looks the way that this one is looking. i mean, we are looking at an over 50% reduction of our traditional commercial fishing season. >> reporter: because the state experienced one of the driest years on record, water ways that would normally carry young salmon out to sea are now hotbeds of dirt and dust. >> i'm standing currently 40 feet underwater, or should be standing 40 feet underwater. >> reporter: governor gavin newsom declared a drought emergency from a cracked lake-bed in april. >> the hots are getting hotter. the drys are getting dryer. >> reporter: iconic chinook salmon need cold running water to survive. they hatch in rivers, then migrate to the sea to mature. after a couple years they swim

back to where life began to reproduce, or spawn. but this year studies show fish born in the wild will likely die. environmental scientist jason julian. >> survival has been shown to be very dependent on temperature. as well as flow. and the temperatures that we're seeing now are anticipated to have pretty low survival for fish that are released in the river. >> reporter: that's why hatcheries like this one near sacramento are jumping with activity. to save the species the california department of fish and wildlife has launched a massive operation. >> this is pretty incredible. what you're look at is nearly 700,000 juvenile salmon being sucked up this tube and put into one of seven tankers. with rivers so low, this is what migration looks like, and it's just one stop along this very unusual journey. the fish are hitching a ride inside 146 trucks, traveling more than 100 miles to the pacific. >> all right. here we go.

john mcmanus heads up an association of fishermen who advocate for sammon and ecosystem protections. what does a herculean effort like this mean for the salmon population? >> actually, in the short term this gives us hope and we're happy they're moving these fish. but it's also a very sad testament to what's happening with our rivers in the middle of this state. >> reporter: what's happening to california's rivers first became a concern nearly a century ago, when dams were built to distribute water to crops in the central valley. damming is believed to have destroying as much as 95% of salmon habitat. hatchries have helped make up for some of the loss. but this year's drought means they now have to make up for all of it. >> salmon are the canary in the coalmine. they're a proxy for many other species in the environment that also rely on the very same water, the very same environmental conditions to survive. so when salmon are going down, many other species are going down. >> reporter: to prevent the tiny fish from become a buffet for

sea birds, release sites are rotated. these were freed at night beneath the golden gate bridge. we followed our school of fish as they were towed to a spot near mare island. in all more than 17 million will be released here into the san francisco bay. nothing about this is natural but it's their best chance at survival. >> reporter: it's estimated about 80% of the young salmon taken for a ride will grow to maturity. sarah bates is appreciative of the work being done to protect the fish and preserve a way of life. >> every fish feels like a little tiny victory. in reality, they're just one part of a much larger ecosystem. and that ecosystem depends on water flows in the

so if you plan on spending any time in the ocean off southern california this summer, you may be alarmed by the growing number of great white sharks swimming right offshore. but you may be even more surprised to find out that shark experts insist they're not really a threat. well, carter evans got on a paddle board to test that theory. >> reporter: getting in the water with great white sharks seems like a terrible idea. i don't dare stand up on this board. we are just off the coast of santa barbara. and within minutes -- >> this shark is so close i can almost grab its dorsal fin. it is right underneath me.

now, scientists say that shark is not interested in me or other people. >> reporter: watch this huge shark swim right up to these unsuspecting children and just swim away. the population of these great whites off so cal beaches is exploding. >> i can only see it now because i'm getting up high. if i were a surfer i'd be lying down and i'd have no idea it was underneath me. >> oh, my god. don't bite him. >> reporter: wedding photographer carlos gomez started capturing these stunning images off the beach last year when the pandemic dried up business. >> almost every time i see an interaction with a human and a shark my heart does pound. we've all been conditioned ever since "jaws" came out to fear that interaction. >> reporter: but this is far from "jaws." watch as a large shark calmly cruises the surf line-up. this one approaches a family. and a swimmer is headed right toward another. all of the sharks seem uninterested. despite the fact that people are

out there thrashing around and their hararms are hanging off boards and legs are hanging off boards sharks just ignore it. >> reporter: chris lowe is director of the shark lab at cal state long beach. >> why don't they want to eat us? >> we don't really know the answer to that question. first of all we're not close to being on the menu. >> reporter: most of the sharks spotted off southern california beaches are juvenile great whites. despite their size, they're only up to about 6 years old and very inexperienced hunters. >> taking off. >> reporter: lowe's team showed us where the sharks use the warm coastal waters as a nursery. >> when they're born, they're completely on their own. the safest place for them to be is in shallow water. they have to learn to feed on what's there. and the number one thing that's there are stingrays. >> reporter: carlos's video shows that they're very aware the surfers are there. >> yeah. in fact, we've been able to document sharks recognizing that somebody's nearby. so they know the sounds of a person swimming and surfing. >> reporter: so they've learned

that we're not a threat. >> kind of seems that way. >> reporter: but lowe says that could change if people get too comfortable and start going after the sharks. >> they're a wild animal, and if they feel threatened they will defend themselves. >> reporter: in 2019 the coast guard had to airlift a surfer who was bit binn a shark off santa rosa island. but lowe says unprovoked great white shark attacks around here are extremely rare. i mean week, essentially telling people here don't worry about the baby great whites in the water. but does the same thing apply on the east coast? >> actually, no. there we have adults that are there to feed on seals. and those seals are sharing the beach with people. so that's a v very differerent situation. even in northern california i'd be a lot more hesitant about getting in the water. > reporter: but off the so cal coast -- >> this shark is just swimming to calmly and so gracefully right now. >> reporter: lowe's team is working to eventually predict the conditions that could lead to encounters between sharks and people. >> i'm kind of hoping in about

five years you'll get a rip current report and you'll get a shark report. >> reporter: lowe and his team say these videos and my interaction are examples that humans and great white sharks can freedom. it's at the core of who we are. the freedom to live without fear. to jog where we please. to wear a hoodie. the freedom to breathe. before we celebrate the freedom most americans have, we must fight for the freedom all americans deserve. because all lives can't matter, until black lives matter. ♪ thank you for interviewing with us. what are your greatest strengths? well, my differences are my strengths. those of us with intellectual and developmental disabilities are highly motivated. we are leaders and innovators. we are changing the face of work for the better one customer at a time.

you may not realize this but americans throw out about 150,000 tons of uneaten food every year. that works out to about a pound of food per person each and every day. straight into the trash.

now, that's not only waste but it's also damaging to the environment. rotting food in landfills makes up 7% of all greenhouse gases worldwide. different countries have their own laws for dealing with uneaten food. in south korea, for example, they force restaurants to recycle it. and they make residents actually pay by the pound for the food they throw away. ian lee has more. >> reporter: it's lunchtime in seoul and they're serving up quite a spread. south korean meals typically have free and unlimited side dishes. and when diners don't finish their food it goes to waste. but instead of chucking the leftovers in the trash, restaurant owners are required by law to separate food waste for recycling. it's the same at home. residents pay for every pound of food they toss. either in a prepaid bag or at a machine that weighs the waste. in the summer it smells bad, this garbage man says. it was that stench of rotting

food from landfills that mobilized south koreans to make a change. activist kim mewa says intense protests forced the government to turn a nation of food wasters into food recyclers. three decades later more than 95% of food waste is recycled, becoming compost, biofuel, and at this factory it's dried and turned into chicken feed. south korea's system isn't perfect, though. there's still a lot of food waste to recycle. and processing plants are struggling to make a profit as most provide their services for free. but many residents say as long as that smell stays away they're happy to continue to pay. ian lee, cbs news. >> and that is the "overnight news" for this thursday. for some of you the news continues. for everyone else check back with us for "cbs this morning" later on. and of course you can follow us anytime online at cbsnews.com. reporting from the nation's capital, i'm errol barnett.
