Earth has a special calendar called the geologic time scale…We are currently in the Holocene Epoch, but some scientists believe we have entered a new time called the Anthropocene or the “Age of Humans” because of our impact on the planet. One of the biggest changes humans have made is inventing and using plastic..Because plastic is now found everywhere, some scientists, like us, think we have entered a new stage in Earth’s history called the Plasticene…
Beaches and coastal dunes have always supplied sand for a wide range of uses, and initially the extracted volumes were limited to buckets, wheelbarrows, or small pickup truck loads. However, starting in the late twentieth century, and thanks to urban development, especially for coastal tourism, coastal and river sand has been extracted at an accelerated pace, and on a much grander scale…
Vanishing Sands: How Sand Mining is Stripping Away Earth’s Beaches by Orrin Pilkey, et al – Duke | Nicholas School of the Environment
A new book from Duke University Press, “Vanishing Sands: Losing Beaches to Mining,” casts light on the shadowy world of sand mining through case studies that illuminate its disastrous impacts and a concluding chapter that proposes common-sense solutions.

The human association with water, particularly shorelines, is a case in point. We do not perceive the history of place, and globally we occupy sites as if they are unchanging, not realizing that in fact they are of high risk.
Santa Veronica Beach, Atlantico, Caribbean coast, Colombia: A model of small community, beach loss, wrong responses; By Nelson Rangel-Buitrago, Adriana Gracia & William J. Neal
Santa Veronica is one of numerous recreational beach developments along Colombia’s Caribbean Coast most sharing a similar history of shoreline retreat, perceived as shoreline erosion, and the attempt to hold the shoreline in place through the use of shore-hardening structures.
Colombian Pacific Beaches at the Mouth of Bahia de Buenaventura; By William J. Neal & Orrin H. Pilkey

Only two roads lead over the Andes to access points from which the islands and their few, very small, subsistence coastal villages can be reached by boat. By William J. Neal and Orrin H. Pilkey
