Sand Extraction — A New Environmental Hazard To Our Beaches?

A few days ago I was drawn to an environmental hazard that’s taking on unknown proportions. In fact, most people aren’t even aware of this. And everything has to do with sand extraction.

I’m not talking about any sand, but about beach sand, the one that gets into your bikini, with which kids build castles or even the one that we crunch when we eat a clam. The same sand that makes up the ocean bottom that forms many of the waves that we are accustomed to surf.

This is the same sand used to make some products without which we no longer live: glass, computer chips, solar panels and even toothpaste. But the primary purpose of sand extraction is construction. And this, unfortunately, is increasingly growing.

Sand Extraction Environmental Hazard

Sand Extraction to levels never seen

Over the past 30 years, demand for sand has increased more than 300%, with China contributing to this growth.

The list of countries that are big sand consumers continues with Dubai using this material to build its famous artificial islands. Although it has a vast desert area, their sand isn’t suitable for construction material. Unlike the one that’s extracted from the sea.

Also, Singapore has resorted to sand to expand its territory, responding to their population growth.

An Environmental Hazard

Of course, these levels of sand extraction had to have impacts on the environment. And they aren’t few:

  • Between 75% and 90% of the world’s beaches are retreating
  • 24 islands in Indonesia have disappeared
  • The Maldives are in danger of disappearing by 2100
  • Without the natural barrier that the sand offers, salt water begins to invade the soil and damage agriculture
  • Dredges used in sand extraction destroy the natural habitat of several marine species

Protect the beach

But if we need sand, what’s the solution?

Recycle! Recycle! Recycle! Recycled glass not only serves to produce new pieces of glass, but more significant particles can be used to build concrete.

Speaking of concrete, recycling can also be used in construction, particularly in the road sector.

And let us not forget clay. The process of transforming clay into a material with the same concrete strength has recently been patented and can offer up to 20% less CO2 emissions. Win-win!

To get an idea of what this market involves, the levels of sand consumption and the environmental hazard or the dangers behind the business, I leave you with this infographic.
