Apa

Planeta este acoperită de apă în proporție de 71%, din care mai puțin de 1% este apă potabilă sau dulce și poate fi consumată în starea ei naturală. Mai concret spus, există aproximativ 1.5 miliarde de km cubi de apă pe Pământ, adică echivalentul a 800 de miliarde de piscine olimpice. Din aceasta, 97% este sărată, 2.1 % este închisă în calotele polare şi mai puţin de 1% este disponibilă ca apă potabilă. Cea mai mare parte din apa potabilă a planetei o putem găsi în ghețari.

They’ve sailed across Southeast Asia for centuries. Now, these sea nomads are being forced to live on land

Bilkuin Jimi Salih doesn’t remember how old he was when he learned to dive, only, that all the men in his family can do it.

It might have been his grandfather who taught him, or his father, or even an uncle or cousin. He recalls swimming dozens of feet underwater among the reefs, collecting spider conches, abalone and sea cucumbers to sell at the local fish market.

“One of our specialties is that, because we live on the sea and we’re always in the sea, we can dive in the water for a long time,” says Salih, via a translator. “We learn by observing, and from there, we develop our own technique.”

To most people, Salih’s free diving skills are highly unusual; but not to his community. Salih is Bajau Laut, an indigenous seafaring group in Southeast Asia that has lived a semi-nomadic lifestyle on the ocean for centuries. Living on boats and fishing for income and sustenance, the Bajau Laut aren’t just reliant on the sea: they’re biologically adapted to it, with larger spleens that give them the ability to hold their breath for far longer than the average person.

“We’re very comfortable in the water,” says Salih. The 20-year-old was born on board a lepa, a type of houseboat, on the shore of Omadal Island, off the coast of Semporna in Malaysian Borneo.
