The second conditional

If you were to jump into any random spot in the ocean,

Adverbs of manner

you would probably see something like this.

Because we have taken them out of the water

Today I want to propose a strategy to save ocean life,

and the solution has a lot to do with economics.

In 1999, a little place called Cabo Pulmo in Mexico

The fishermen were so upset not having enough fish to catch

that they did something that no one expected.

Instead of spending more time at sea, trying to catch the few fish left,

When we returned, 10 years later, this is what we saw.

was now a kaleidoscope of life and color.

We saw it back to pristine in only 10 years.

Including the return of the large predators,

like the groupers, the sharks, the jacks.

are making much more money now, from tourism.

Now, when we can align economic needs with conservation,

And we have seen similar recoveries all over the world.

I spent 20 years studying human impacts in the ocean.

But when I saw firsthand the regeneration of places like Cabo Pulmo,

So I decided to quit my job as a university professor

to dedicate my life to save more ocean places like this.

In the last 10 years, our team at National Geographic Pristine Seas

some of the wildest places left in the ocean

and worked with governments to protect them.

These are all now protected, covering a total area half the size of Canada.

These places are the Yellowstones and the Serengetis of the sea.

These are places where you jump in the water

and are immediately surrounded by sharks.

because the sharks are a good indicator of the health of the ecosystem.

that take us to the ocean of 1,000 years ago.

But they also show us what the future ocean could be like.

Because the ocean has extraordinary regenerative power,

we have seen great recovery in just a few years.

We just need to protect many more places at risk

so they can become wild and full of life again.

is fully protected from fishing and other activities.

Studies suggest that we need at least 30 percent of the ocean under protection

not just to save marine life, but to save us, too.

Because the ocean gives us more than half of the oxygen we breathe, food,

Now, is there a way to accelerate ocean protection?

And it involves us looking at the high seas.

Now coastal countries have authority over 200 nautical miles from shore.

Everything beyond those areas are called the high seas.

but they all are, so it's a little like the Wild West.

And there are two main types of fishing in the high seas.

Bottom trawling is the most destructive practice in the world.

Super trawlers, the largest fishing vessels in the ocean,

have nets so large that they can hold a dozen 747 jets.

These huge nets destroy everything in their paths --

including deep corals that grow on sea mounds,

And fishing near the surface targets mostly species

that migrate between the high seas and country's waters,

And many of these species are threatened because of too much fishing

Until now, it was difficult to know exactly,

because countries have been very secretive

But now, satellite technology allows us to track individual boats.

we are presenting the data that you are going to see.

I'm going to show you the tracks of two boats

using a satellite automated identification system.

This is a long-liner, fishing around the southern coast of Africa.

After a few months fishing there, the boat goes to Japan to resupply,

and shortly after, here it is, fishing around Madagascar.

This is a Russian trawler fishing, probably, for cod,

and then across the high seas of the north Atlantic.
