Beach nourishment is the latest chapter in a never-ending tale of erosion.

About 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.

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. Check out

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

Don't hurt b*tches
They are people too!
factually incorrect, as always, Vox. @ 0:55 its not waves, as you mention, it's man made climate change. im so disappointed that you claim to be a post truth, alt left rag and you didnt come out of the gates with climate change or some stupid stuff. Just blame it on the bad orange man and move on to your next propaganda piece.

for clarity, i didnt watch the full video or even intend to. its Vox, after all.

Better solution, stop building things on sand next to an ocean!
I finished watching this video and am pro-beach nourishment. It makes sense to do it in the areas that are generating revenue for the country. It's and investment that's paying off.\

I’ve been to lido key, they told us it was because of the hurricane, but I don’t know if that’s true. The beach was only like 10 feet at low tide and at high tide, there barely wasn’t a beach. It was pretty sad

Beach lives matter!

This is apart of another problem that's bigger than this issue. Some might say it causes this beach issue.
with the help of reefs they could slow down waves and tsunamies and in turn reduce erosion

Omg I thought this scenario only existed in my creative mind. People actually doing this for decades!? Tax funding on this??? People really are dumber than nature 🤣 or so arrogant they think they can be stronger

Stop building on the shorelines? Wtf americans?
Grey Plague
Wow, that's almost something Sisyphus would do.

Compact the sand with rocks

You started this video by saying nourishment causes long-term environmental problems, but nothing in this video addresses that. It sounds like there's no problem with nourishing beaches. It sounds like there's a problem with who gets the nourishment, and a problem with people's perception of the nourished area. And that's fair, so why lie about the premise of this piece? That is a weirdly deceptive choice.

You can't rebuild a beach when the ocean sea level is rising. How about stop polluting and build renewable.

With original music by Tom Fox:

Colombia is currently dealing with a massive wave of refugees coming from Venezuela. Venezuelans are fleeing their home because of a severe economic crisis under President Nicolas Maduro. There are high inflation rates and there isn’t enough food available for people within Venezuela to even eat. Thousands of Venezuelans cross the Simon Bolivar bridge located at Cúcuta every day and Colombia doesn’t seem to be turning anyone way.

This borders episode looks at why Colombia doesn’t turn away these refugees, the shared history of the two nations and how there may be a limit to Colombia’s acceptance of incoming Venezuelans.
