"Each sand grain is about a tenth of a millimeter in size. When you look closer, it’s really quite amazing. You have microshells there; coral; fragments of other shells; olivine; bits of volcano; tube worms — an amazing array of incredible things exist in sand.
When we’re walking along a beach, we’re actually walking along millions of years of biological and geological history. We don’t realize it, but it’s actually a record of that entire ecology. If you look at different sands from different places — every single beach, every single place where you look at sand — they’re different.”
