There's no shortage of companies trying to develop alternatives to meet what about sushi?

Specifically tuna made without tuna fish but instead from tomatoes, sesame oil and soy sauce.

Some foodies say serious sushi.

Sticklers may not spring for it, but several others have.

When it comes to seafood, are there mawr than fish in the sea?

The human population is growing exponentially.

In 1800 they were about a billion people on earth.

Today, there's more than seven times that on by 2100.

Estimates say there could be nearly 12 billion people around the globe.

That rapid growth comes with lots of problems.

One of the biggest.

Our food supply may not be able to keep up when it comes to seafood.

The rising number of consumers mixed with the growing popularity of foods like sushi has led to overfishing.

The Pacific bluefin tuna is a sushi staple.

Its population has fallen 97%.

Demand is only getting higher and higher and higher.

And one of the big problems we have today is that we are overfishing tuna, and it's only at 3%.

At the height of its stock, That's James Core.

Well, he's been a chef for over 30 years, and he's the founder of a company called Ocean Hunger Foods.

His solution to the dwindling tuna population.

Tomatoes it, stay with me.

There's five tastes, so we have.

We're familiar with.

Sweet, sour, salty, bitter.

But there's the fifth taste, called umami, and that refers to savory and sushi in particular.

You have soy sauce, you have rice.

That's my new mommy.

You have seaweed.

That's my new mommy.

You have the tuna.

That's my new mommy.

But also that what I knew mommy or tomatoes.

The only problem was, is you wouldn't have a great sushi experience if the ah he me taste like tomatoes.

So the rial technology that we developed, uh, came from the process on how to remove that tomato flavor.

Yeah, keep great texture, but create this kind of neutral platform in which to carry Japanese flavors or Latin American flavors or Mediterranean flavors.

So it's basically like the tomato is a vehicle to get those flavors into your mouth.

Exactly.

Ocean hugger makes plant based alternatives to seafood.

The tomato tuna is called a he me.

The company is also working on salmon made from carrots and l made from eggplant.

Well, now, let's dig in there.

Okay?

All right.

We're gonna dip in a little of the soy sauce.

It really does look like tuna.

Wow.

All right.

Yeah, that's really good.

Right now, let's go.

What's happening?

Sushi roll form.

Uh, I'm not very good with chopsticks.

Hmm.

I would totally, totally grab that for lunch.

Was opposed to regular e Don't have to work with the mercury e Don't have to worry about.

Like you're killing a delicious salt pipe tuna.

So I was pleasantly surprised.

I mean, it actually tasted good, but if we look even further into the future, there will be less usable land to grow crops like tomatoes and carrots.

That's where some scientists thing algae comes in.

Yep.

Algae like pond scum.

It might not sound very appetizing, but algae is actually high in protein, and it can grow where other crops can't.

All you need is sunlight, air and water.

We're not in dire need of algae based snacks just yet, but one company called nonfood wants to get ahead of the curve.

It smells.

Their first product is called non Bar And instead of trying to emulate flavors we already know and love, they decided Thio embrace the algae.

So I'm gonna try this e smells a little funky.

I'm not gonna lie.

Mhm e mean, it was gonna take some getting used to.
