Crazy Idea To Reduce Sea Levels

Would it be possible to dig out large volumes of earth from under the Ocean to create extra land for things like agriculture and reduce sea levels at the same time?
I know it's a crazy idea but would it be possible?

I think the idea of displacement cancels that idea. If you remove earth from under the ocean, then put it back on the ground (above sea level), in theory, it will push the ground back down from the weight and force the level of the sea back up again.

Maybe people shouldn't have colonized so close to the beaches.

Good point, maybe I should have thought about it a bit more before I posted here. I probably wouldn't have thought of that anyway. Thanks

Edit I meant wouldn't. Not would

I do believe that they should work on the Pacific Garbage Patch, seems that might do more good to shovel it out of the ocean.

What a mess. Bad thing of it is, its all from us humans.

I remember reading something about that a while back, it was about the Japanese complaining about rubbish washing up on their beaches from America. It's not from us humans is it

I was bored and I love math like this. I hope its all correct.

Total surface area of ocean:
139,500,000 Square miles of ocean * 640 acres per mile = 89,280,000,000 Acres of Ocean

1" of rain on 100 acres would be 2,715,400 gallons so:
89,280,000,000 Acres of Ocean / 100 = 892,800,000.
892,800,000 * 2,715,400 = 2,424,309,120,000,000 gallons of ocean per inch.

Now One US gallon is 0.133681 cubic feet so 2,424,309,120,000,000 * 0.133681 = 324,084,067,470,720 cubic feet of dirt that need to be moved to land, to lower the whole ocean by 1 inch.

18.3 trillion tons dry.

Would probly be easier to pump water to the artic to allow it to
refreeze to create larger ice caps.

Wow genius, thanks for your input

That's one heck of a lot of dirt, maybe it's not possible then, but if it was then one way of doing it would be to dig out tunnels under the sea and blow out the support columns so it collapses into itself, one tunnel at a time
