- Hidden beneath the surface of our coastal seas are towering forests - of kelp. These underwater ecosystems are as crucial to our environment as their land-based counterparts. We’ll explore them alongside conservationists who are working to restore these threatened habitats. We'll also meet some adorable sea otters and learn about the role they play in maintaining the balance in this sensitive environment.
Hosted by Joe Hanson from Be Smart, Overview uses stunning 4k drone footage to reveal the natural and human made marvels shaping our planet--from a 10,000-foot view--literally.

I've been to Morro Bay and saw otters raising babies.
So precious.
We can't afford to let them go.
You should see what they do to make those babies
I'm from the Midwest and live in LA yeah I'm seeing Leo career State Park and I've been to Morro Bay but I haven't been to Monterey Bay and really that's all I want to do I want to snorkel and learn how to kayak and swim and take photos and it's literally all I want.
I don't know if the Pacific serve learner goes up and down and stops at stops from Burbank to Monterey Bay but if it does I would like to take it.
But we need to think of all animals and wildlife like this.
I live in Morro Bay, the sea otter population is thriving finally! I was born in SLO County and couldn't be happier. There is an abalone farm 25 minutes north of Morro Bay. The kelp forests are amazing! Due to a lot of activism, let's all do our part please!
Also kelp is a huge help reducing coastal erosion. They had a similar problem in the island chains of Alaska. Besides the erosion the fish population was very low. The busted butt, brought the otter back and the forests started growing and the fish rebounded.
They detonated a nuclear bomb up there. They relocated some of the otters before they set it off. the urchins killed the kelp there, too, and they started to reintroduce them to try and bring the ecosystem back.
@@shihtzusrule9115 ahh, I didn't remember why that ecosystem was screwed up.
My heart is broken at hearing that 96% of the kelp forest from the California coast has been lost 😢
And that is why the work of the Monterey Bay aquarium helping the sea otters is that much more important let alone larger re-introductions.
Aside from what needs to be done, see otters should definitely be a California icon for their importance.
We also harvest kelp for food. I eat kelp for the Iodine. I am allergic to Iodine and every so often I buy kelp. Not that much or I break out. According to the book of Revelation, God is going to recreate Earth. Hoping no more allergies.
Haida gwaii has been released back into the hands of its traditional caretakers. There are many otters and kelp forests there still and now perhaps they too will spread.
Southern sea otters (the ones in the video) are only found in California. There are two other subspecies of sea otter - Northern sea otters (range from Washington coast up through Alaska) and Russian sea otters (their range is Russia down to Japan) Those populations are larger, in the thousands - but Southern sea otters in the wild are only around 3,000. And their range is limited - mostly central California. They have rebounded from almost being wiped out from the fur trade of the 18th-19th centuries, but it took a long time, plus federal protections like the Marine Mammal Protection Act and the Endangered Species Act made a big difference. But their population is still fragile and anything like an oil spill or disease could wipe them out.
@@scraller and that is what makes the Monterey Bay aquarium’s work that much more important. I got to see the sea otters last memorial Day weekend with my family visiting the area.
Have you ever noticed that all of the people that are trying save the world and the nature are so beautiful. In and out
Kudos to all the conservationists, scientists and many others helping to restore the funtion of this planet. More and more people now realize the damage cause by human greed which is still ongoing and working to reverse the damage
@Joe Hanson - your presentation of the relationships between kelp, sea urchins and otters 🦦- was fabulous. I love the optimistic joy in your description.
I’m more fatalistic and pessimistic- and, still hold a small ember of hope for meaningful change during my grandkids lifetimes.
“Putting a piece of hope out” I love that.
Ive been there! Seeing otters living their best life is great
Wow. Not only are we regenerating our land, but now we are regenerating the ocean. Awesome!
I was born in SLO and been here my whole life. Otters are everywhere in Morro Bay. Wasn't that way when i was growing up. Go conservation!!
I love exploring these underwater forests. Such a cool video!!
When I was in my early 30's, I got my PADI certification, and over the next few years, did many dives in kelp forests along the central coast from Big Sur to Fort Bragg. On a day with good visibility, those kelp dives were among the most amazing I ever did.
They gotta step up now. These otters need to be saved.
That's so heartbreaking to hear how much Kelp forest we've lost. 😢 I really hope the west coast steps up their efforts.
would you be willing to pay a tax to try and correct what humans have damaged over the years and restore the ecosystems? would you vote for politicians who made something like this an issue? Not just focus on the stock market, economy and immigration?
@@shihtzusrule9115 Yes if those same politicians did something to help redistribute wealth away from the rich back to working people
One of the causes people can donate to on the California state tax return is a sea otter restoration fund. There’s also a sea otter California DMV vanity plate.
Thanks for the efforts for reviving them back.
I love how you showed both sides of the conservation effort.
Thanks for trying to save the kelp forest, save the otter, God bless your work, amen, save the world, great job
Otters are indeed the cutest animals ever!
Except when they breed forced gang-style
Honestly crazy how perfectly Otters evolved to trigger our sense of cuteness. like dogs did it on purpose but otters? pure coincidence
i feel the same way about harbor (and other) seals
Yeah though we did hunt them to extinction in multiple places so unfortunately people didn’t find them cute enough.
Interesting to see another angle of attack on the urchin problem. I can't recall now if it's north California or further up into the Pacific Northwest but I remember hearing about folks making steps towards harvesting urchins - not so much a deliberate overharvest, but an attempt to gather in LOTS of the creatures, take them OUT of that environment, then bring 'em inland and essentially fatten them up for human use as food. And that's not the only thing happening along the Pacific coast. It's good to know that there ARE people taking this seriously - I just hope we can also get policy makers involved in a way that promotes sustainability and restoration of habitat.
There's been programs where they certify divers to carry a hammer and go smash as many urchins as they can in urchin barrens. They do it all. That actually turned out to be hindering the effort though, not helping, as the urchins would eat their fallen comrades and just get bigger. Whoooooo knows, maybe the otters aren't a keystone species (which is actually scientifically proven at this point, depending on who you ask), and they're actually PLANTING the kelp 😮
This was the best video ever by PBS Terra
Thank you for bringing attention and educating us on this situation, and showing what is being done to help fix things.
This ties in well with the other Nature series on the Maine sea coast, and their efforts.
As one who challenged the waters and was certified by NASDS at 14 years, I enjoyed the kelp. I enjoyed a lot of things that are no longer there.
Thank you for all helping in these endeavors!! ❤
One of my favorite childhood memories is of a beach day with my mom, she was ‘popping’ the balls on kelp and it grossed me out while making us laugh hysterically… this was 50+ years ago, when the tide left kelp on shore all along the coast. It used to be abundant. So sad to realize what’s been lost.😢
I recall a global vote for cutest animal, about 10 or 15 yrs ago and the otter won, hands down. (Otter be a pun in that, otters having hands and all.)
Just did the Nootka Island Trail this past week (off of Vancouver Island, Canada) and we saw lots of kelp and sea otters! The Canadian west coast was hit hard by that starfish/seastar disease over the past decade as well, but they're slowly returning. I had no idea how inter-related starfish, urchins, kelp and otters were in this way. Great video.
huzzah!!!!!! keep these coming! more kelp! more urchins! MORE OTTERS!!!
🦦🦦🦦Go Otters! Help save the kelp forests of California!! Oregon too!👏👏👏

Hats off to them..these people are really working hard
I'm a Central Coast otter lover. They made a great comeback once. Thank you for helping them do it again.🦦😄🦦😄🦦😄🐟🐠🐡
Love the work they are doing.
Otters and Beavers out here trying to save the environment more than some humans.
Diffently more than pretty much all governments.
I loved this. We are dealing with similar issues in Bonaire but with the loss of coral due to climate change and Stony Coral Tissue Loss Disease.
Great video. Thank you.
Why don't they have a 5-star or 0-10 ranking? This just doesn't deserve a simple thumb up, but the max like.
Love this stretch of coastline, Monterey Bay is one of my favorite places in the world. Getting to kayak among dozens of otters in Elkhorn Slough was amazing, although we had to backpedal a lot because state law requires us to stay 30 ft away from any otters.
I love the coast around the Big River... amazing water and wildlife
Love Rosa, the best sea otter mama to ever live. Enjoy the sea food great sea food buffet in the sky :)
Wonderful! There is huge potential 👏🏻👏🏻👏🏻. We have restored rivers, lakes - we can do this as well 👍🏻
I hear sea urchin is pretty tasty too, very umami and creamy texture, fantastic eating. We can definitely do our part to help fill this gap until the otters have a stable population and the kelp is able to recover.
Excellent reporting! Many thanks!
Video starts: awww cute!, Video Mid: horrifying news, Video End: maybe some hope?
if i could like this video multiple times, i would
It is my understanding that the dearth of the "Crown of Thorns Starfish" is a major factor in the explosion of Sea Urchin populations. Sea Otters are only a piece of the puzzle. The Kelp forest needs the "Crown of Thorns Starfosh" to be repopulated.
The starfish became the major predator after the otter were already nearly wiped out; they do discuss this in the video.
The video covers otters were primary, then wiped out, next starfish took over, and died of disease.
I wonder if overpopulation of starfish facilitated the disease that caused starfish to break apart and die out?
Crown-of-thorns is a tropical sea star that feeds on corals; the sunflower star is the California predator that feasts on urchins.
@@kpetersonkpeterson6712yeah i was so confused about this convo because we dont want no more thorned starfish, just sunflower 🌻
I really wish the Terra shows (Deep Look, Orverview, ect) who do a lot of stuff in California (cus thats where they're based I guess) would look North of the 42 parallel to Oregon and Washington.
Kelp forests up here have been decimeted too, but unlike in the Salish Sea, or in California where Sea Otters, however slowly, have been reintroduced, the same efforts up here havent worked as well.
Its a different version of the same story, and one thats worth telling.
Contact your congressional representatives! I bet that Terra focuses on CA because of the Monterey Aquarium. Congress can get more money to your state universities!

Thank you for this video. I'm optimistic that we humans can fix our mistakes have done.
Unfortunately it takes a lot of sea otters to protect kelp because otters don't like urchins very much. So it's only when their preferred prey, like abalone, have been reduced by other otters that they feed on urchins.
96% of that kelp forest is gone????!!?!! God
It's disgusting isn't it...Cheers from New Zealand
Yeah that number blew me away as well... Not surprising though, it's California🙄
@@DMTrance87this trend is worldwide, nature is dying
Are Otters ocean cats ? I love them 😮Cheers from New Zealand
RIP Rosa ❤
Bones for the boneworm
Great video! Otters & humans co-exist in simular environments... an otter called Duncan*😊❤
I think Tasmania lost its kelp forest. Urchins that previously couldn't survive the cold water got established due to a slightly warmer ocean. Maybe they can reseed, but only if they can find a predator for the urchins.
There's an episode of Octonauts about this! Such a pity to hear the forest has declined so much though
In Morro Bay, the otter population is rebounding. Due to conservation, activism, and loads of volunteers.
3:02 where’s George and Gracie? 😂🖖
Thank you 🙏🏼
One otter at a time sweet nature
60 cm a day. wish my garden would grow like that. Remember the surfboard stealing otter in Santa Cruz? She had a number, too.
I remember! Wasn’t it mainly in Santa Cruz?
Andrew Kim: Planting kelp is like putting a piece of hope out.
Me, a Korean-Korean: Oh look, a "Gim" is farming "Dasima" from the other side of the world. His ancestors must be proud😅
CA, OR, and WA need sponsoring and support agencies for urchin fisheries - and sell the product to domestic and foreign retailers. This allows translocations of northern kelp bed nurseries for restoration of kelp beds along the coastlines, ... and re-establish scattered sea otter populations.
I am not an ecologist, tree hugger, or wild lover of animals - just a pragmatist.
Man removed the "predators" in the wild, and distorted the entire working ecology of the system.
- They destroyed the wolf population, having the elk and deer populations skyrocket, decimating the young forest saplings near the rivers, creating greater flash floodings and erosions of river banks and flood channels.
- They destroyed the beaver population, who built the valley, ravine, and canyon dams stopping floodings, and allowing the growth of riparian woodlands (that the deer and elk munched on versus the beavers caretaking and harvesting their own river forests).
- They destroyed the sea otters, who removed the sea urchins, that kept the ocean kelp beds intact, preventing coastal shoreline erosion and transmigration of sea sands, creating greater wind, water, and weather decimation of the land.
- They destroyed the river otters, who controlled invasive species (lampreys, suckerfish, etc.), who destroyed the fishery populations.
- They overharvested to decimation the local timber forests, creating greater flood and landslide situations.
- They overharvested to decimation the local fishery populations, creating other river, creek, and stream populations that controlled the water insect populations.
- Restore the wolf populations, keeping the deer and elk populations under control, recreating the needed riparian forest zones.
- Restore the river and sea otter populations, keeping the invasive species and sea urchins under control, restoring the clean waters, kelp beds of the coastline, and local fishery populations.
- Restore the beaver population, in tandem with the wolves, recreating the needed riparian forest zones, that also protected the fishery populations.
- Restore the riparian forest zones around the waterways, saving the waterways, and downstream watershed geology and ecology.
- Restore the fishery populations, keeping the waterways clean and intact.
- Stop overharvesting of the timber forests, with proper maintenance, forest duff and fire-prone situations.
- Stop overharvesting of the fisheries.
- Also support the enhancement and population restorations of purple martins (swallows), bats, raptors, bluebirds, tweeties, ... controlling the daytime and night time populations of flies, biting flies, mosquitoes, gnats, noseeums, chiggers, ticks, ... small rodent populations, disease controls within native wildlife.
Unfortunately these urchins are not the tasty kind that people already eat. The species that are considered tasty by humans produce a ton of roe, and purple sea urchins do not. There have been pushes to try to get people interested in eating them, but like trying to get people to eat nutria/coypu, it hasn't been particularly successful. They're not not what people are interested in eating in large quantities.
@@Tserit turns out they are tasty, just that they don't produce the volume of the red.
Marketing them as beneficial to eat, like lionfish in Florida will help.
Capitalism looks for the easiest solution, not the most beneficial solution.
If we can't change that, we can at least utilize it to strategically undo that horribly long list of problem our ancestors created.
@@TragoudistrosMPH They have been trying to do this for many years, however, and it just hasn't caught on. There have been numerous videos and articles and pop-up restaurants and so on over the years and it hasn't put a dent in the urchin population. If it could, that would be great, but so far it really hasn't been effective.
@@Tser people have taken the purple urchins, kept them in captivity and fed them and produced high quality uni.

Ooni anyone?
Normally an expensive delicacy, it could be a cheap treat until balance is restored.
Uni. But yes
9:35 the awkward turn around lol
Indigenous people in Alaska are cultivating kelp for human consumption. They should talk to each other. It was a pbs special with Martha Stewart narrating it.
Fun fact there is a market for uni, but sadly people perfer the red ones not the purple.....
hi joe! i was sent here by joe :)
Otters were hunted for the euroean fur trade long before european settlers arrived in numbers. Native people were a significant part of that economic web long before that. There is a direct line from the beaver wars to the extinction of beavers and the almost extinction of otters in the west.
Hey! Its the "Be Smart" guy! Hey Smart people!
1:12
I just realized I place food on my stomach just like an otter 😂😂😂
RIP Rosa D:
o7
We have an over population in some areas of Alaska…can we transplant them?
I bet you could reach out to the Monterey Bay Aquarium??
Don’t forget about the otter excrement that feeds the algae and kelp. 😅
We live in paradise, it is us who make it hell at times.
These guys need our kelp! We otter save them!
Otters are the Beaver of the ocean.
We otter save them!
I bet you just said that for the halibut.
The natural world has countless systems to control populations from the top down and bottom up. Our species needs to begin to manage our unsustainable practices (through reducing birth rates, re-wilding natural areas, and drastically reducing per capita consumption) through overarching policy and societal changes, before we are forced to do so by resource scarcity and biosphere collapse.
I want views like this to be possible for generations of humans after us to see. At our current rate of growth, that will not happen.
Me: "this is going to be a great video demonstrating restoration ecology."
Me instead: " . . . . BRO YOUR PADDLE IS UPSIDE DOWN!!!" lol
Go Otters!
i am curious about from where are the getting there fund to carry on what they do(protecting kelp).
Otters are Quiche Tone Pisces? That sounds delicious.
Would love to see $1 uni on sushi menus!
Not enough otter b-roll. Too many humans
The sea otter turned out to be a keystone species to the health of kelp forests. I've seen areas of the seafloor overwhelmed by sea urchins and completely devoid of kelp where there are either too few or no sea otters present. Not a pretty sight.
My man looks like beast from X-men before his mutation took over.
good boys

Are we going to talk about sea stars? Hello?phew, finally, halfway thru.
“DONT call them PLANTS” “These are the trees of underwater forests ” 🤓 “underwater PLANT eaters like sea urchins”
i call em babadoos
Given that kelp forests are basically the temperate rainforests of the sea just as coroal reefs are the tropical rainforests of the sea, why not help along the otter & sea star conservation efforts by harvesting some sea urchins ourselves? The stuff in them can be used like butter of the sea & the shells can be used like lanterns & lamps, for example & the spines have been used in apothecarical/pharmaceutical settings. Let's also look into more ways to use some kelp to wash up in similar ranges such as fabrics & those of sea urchins
2:49 5 foot otter?
geez bro how tall ARE you. :P but yeah, sea otters are great :D
We Live On Land But We Are Nothing Without The BIG OCEAN.
Shoutout to the twitch streamer DougDoug for raising over $600,000 for Monterey bay aquarium last weekend
this things look straight out of subnautica. though it could be possible that the things in subnautica is inspired from it as well
Seeing the aquarium, I just thought 'George and Gracie'
Kinda hoping to see Rosa in the vid ngl 🦦👀
