  • Beach nourishment is the latest chapter in a never-ending tale of erosion. Subscribe to our channel! 80 to 90 percent of sandy beaches along America's coastlines are eroding. This is a problem because the developments humans build near them are static. So as beaches shrink, coastal hazards can threaten to damage or destroy homes and businesses while negatively impacting tourism that depends on the beach. The most popular strategy to counter these risks is a process called beach nourishment. Coastal engineers will add new sand to an eroding beach in order to rebuild or expand the shoreline. Watch the video above to learn more about how beach nourishments can help defend the coast but are problematic as a long-term solution. For more, here are the links to our sources for this video: Randall Parkinson on beach nourishment and climate change mitigation: reporting on the high costs related to preserving vulnerable beaches: And for a closer look at the “feedback loop,” read a report on how researchers determined the link between nourishments and development along the coast: is a news website that helps you cut through the noise and understand what's really driving the events in the headlines.

    Beaches aren't the only area where economic disparities are hurting communities. Check out our video on how "levee wars" are making flooding worse:

    The foolish man built his house upon the sand, and the wise man built his house upon the rock. The rich man built his house and industrial properties on the sand such that the government would be forced to provide insurance against natural erosion.

    Jeera Indica Literally all our profits come directly or indirectly from nature. Every single one of them including your job. Don’t come here with the “I am 14 years old and I am very deep” talk

    In Veneto (Italy), we place dams made with big rocks in order to destroy waves. Erosion still happen, but this rebuilding process is done as I remember each 10 years

    In my town of Erie, Pennsylvania we also use “dams”, more like islands, made of rocks to have the waves crash into.

    @Berg Bloodaxe Unattractive is better than having no beach. You could bury the rocks just below the water line. You could also pack them neatly. It's not like you swimming beside the rocks. Sometimes they can be hundreds of feets away.

    It would have been cool if vox at least mentioned some of the several alternative solutions to beach erosion besides beach nourishment.

    Unless you're referring to the fact that mangroves are successive trees. They do too good a job of conserving soil, and will eventually build up the soil to the point where they get out competed by land trees. Though, under natural circumstances, by that point they would have expanded the coasts and moved further out.

  • AKArainkit


    @Chad Leach What do you mean? Mangroves grow quickly and don't get out competed by plants unless they are planted in the wrong areas. The hard part is planting them. They can't be more than a few meters above sea level and need to be covered by water at high tide. The biggest threats to mangrove forests are humans who cut them down for beach front properties, not invasive species, because there are so few land plants or even wetland plants that can tolerate high levels of salt like mangroves can.If by...

    My god, don't we hear enough of that already. We've desensitized to the matter.

    We should rake the coastline, so there won't be any erosion!
