Like grains of sand through the hourglass

 

This post is about sand, or actually, the lack thereof, in certain places where sand is expected.

The beaches of the future are going to surprise us

"Beaches will only require more nourishment as worsening storms wash them away, sea level rise makes it harder to keep sand in place, excessive groundwater extraction causes land to sink and the rivers that once deposited sand on the coast dry up. Already beaches near San Diego and San Clemente, Calif., are shrinking by an average of 4.75 feet per year. Without them, nothing separates the fury of the ocean from the homes, resorts and other buildings that dot the shore.

Even finding sand has grown more difficult; many offshore reserves are already depleted, forcing dredging vessels to venture further offshore to find sand and dig it up from the ocean floor. In some places sand has to be transported by the truckload from inland at considerable extra cost — or even purchased from other countries. The Jewel Grande resort in Montego Bay, Jamaica, for example, imported sand all the way from the Bahamas to build up its beach before it opened for business in 2017."

Mr. Sandman, bring me a dream
And more sand too, while he's at it.
Because time and tide wait for no man, and while we're waiting, the beaches are eroding.
