- [Narrator] A two-hour boat ride off the coast of Colombia

is an island, the most densely-populated island on earth.

(chattering)

Santa Cruz del Islote consists of more than 1,200 people

living on land the size of two soccer fields,

making it four times as dense as Manhattan.

On the island is a school that runs up to the 10th grade,

two shops, and one restaurant.

There is no steady supply of water

and a sole generator that only runs for five hours per day.

There are no police, but there isn't much need for them,

as everyone on the island knows each other.

(children chattering)

150 years ago, the island was primarily uninhabited

and was sometimes used by local fishermen

as a place to rest and take shelter during storms.

Gradually, some fishermen came to build their homes here.

These were the grandparents and great-grandparents

of the current generation of residents.

Despite the close living quarters,

inhabitants on the island say they wouldn't give up

their peaceful existence for anything,

not even a little more room.
