Yaren, Nauru

I FORGIVE you if you have never heard of my country.

At just 8 square miles, about a third of the size of Manhattan, and located in the southern Pacific Ocean, Nauru appears as merely a pinpoint on most maps — if it is not missing entirely in a vast expanse of blue.

But make no mistake; we are a sovereign nation, with our own language, customs and history dating back 3,000 years. Nauru is worth a quick Internet search, I assure you, for not only will you discover a fascinating country that is often overlooked, you will find an indispensible cautionary tale about life in a place with hard ecological limits.

Phosphate mining, first by foreign companies and later our own, cleared the lush tropical rainforest that once covered our island’s interior, scarring the land and leaving only a thin strip of coastline for us to live on. The legacy of exploitation left us with few economic alternatives and one of the highest unemployment rates in the world, and led previous governments to make unwise investments that ultimately squandered our country’s savings.

I am not looking for sympathy, but rather warning you what can happen when a country runs out of options. The world is headed down a similar path with the relentless burning of coal and oil, which is altering the planet’s climate, melting ice caps, making oceans more acidic and edging us ever closer to a day when no one will be able to take clean water, fertile soil or abundant food for granted.
