VIDEO: Purple Urchin Explosion!
News Bytes 11/1/2019 100 Comments


On the Northern California coast, researchers are flying drones. They are mapping and monitoring some of the state’s last remaining kelp forests.

In less than a decade, this region has lost more than 90 percent of its kelp. The Golden State was forced to close its $44 million per year red abalone fishery. That has been rough on outdoor sport and tourism.

"We've had a really stable kelp forest ecosystem for the last 100 years," says marine scientist Cynthia Catton.

So what's behind the kelp crisis?

God’s made creatures and nature to depend on each other in complex ways. But in our fallen world, those relationships get out of balance.

Scientists say an explosion of purple sea urchins have devoured bull kelp at an unprecedented rate. Urchin populations spiked after a disease wiped out sea stars, the urchins' main predator. Then also, a marine heat wave made it hard for the kelp to recover.

The problem has expanded beyond California. Oregon researchers are now reporting a 10,000 percent spike in purple urchins over the past five years. Vast swathes of the Pacific Coast have turned into "urchin barrens." Grazing purple urchins blanket seabeds where towering bull kelp once grew.

Now, one California marine lab is running an unusual project. Urchinomics is turning the destructive ocean pests into a seafood delicacy. They are growing sea urchin roe, also known as uni. Urchinomics CEO Brian Takeda says his company is about turning a problem into an opportunity. “We pluck them up and we 'ranch' them and turn them into premium seafood products."

"Not only will [Urchinomics] be providing this new seafood, but we'll also be helping to restore the kelp forests at the same time," says marine scientist Laura Rogers-Bennett. Urchin ranching is just one possible solution to this coastal crisis. But many more are needed to bring back kelp forests and the marine life that depend on them.

Mirela, yes, I have tried a bite of dried seaweed, I didn't like it. And Nadia, yes, I did watch the video, it was cool except for the part when the guy cut open and ate the urchin.

@Nadia A

you got up at 7:04 just to do WorldTeen?????? Whenever im up that early and dont have to make break fast, I get to work on my school.( normally Math, Latin, or Logic, sometimes Writing, never Music(Violin))


There were probably Halloween toys because it was around Halloween!

@ Gloriana

Haha! Yes I did! And it was the only day we could sleep in a little. Me and my brother desided we were going to get up erly to see if we could get 1st comment on the new articles! So happened you can't comment so I went back to bed!

Solution for Not being able to comment on the articles.

Mabey we could right the name of the article on the subjects part and them comment about that article. I don't know if that's permitted.

@ Gloriana

Here I responded to you on this article. I don't know if you saw it or not.

@Glorianna B

What curriculum do you use?

@Glorianna B

I was the one who disagreed about the Halloween toys earlier. I do see now that they are all Halloween toys and I wasn't saying that in the picture it wasn't a Halloween toy, but I was saying that there was only one toy in the picture so it sounded kind of ridiculous to say they were all Halloween toys.

To above

Well. If you watched the Video then that would have made sens.


That’s a good idea I don’t know why that wouldn’t be permitted! : )



@Bethsarah G

Oh. That's OK. I was talking about the video.

@Bethsarah G

Several. Henle Latin, Saxon Math, Lost Tools of Writing, Suzuki and several more in Violin.

@ Beth H

Ya. But remember the gaming when is to much to much thing...

@Bethsarah G

Several. Henle Latin, Saxon Math, Lost Tools of Writing, Suzuki and several more in Violin.
P.S. I can't remember what I do in Logic right now.
