That’s how much silt the great Mississippi River dumps into the Gulf of Mexico each year. I might add there are a few others that are similar. There are some that dump more, many less.
That is a bunch of bunch of dirt displacing millions of tons of ocean water.
Now, let’s see. Do you suppose that would cause the ocean levels to rise.
Simple solution. Dig some of the dirt back out or pump ocean waters into man-made salt lakes and add lake front property. Make channels for shipping. Add beautiful landscaping for big hotels.
Build a bid wide beautiful mote just north of the Mexican border to stop illegal migration. Well, that wouldn’t work well in the mountainous areas. It’s a thougt, anyway. It sure would be nice to cut down ont the drug traffic too.
