How much deeper would the ocean be without sponges?

lets remove them all and find out............

Now you've done it. You have given ALGORE something else to hype. I can see the newspapers now:

Headline: ALGORE: "Lack of Sponges in the worlds oceans causing level to rise!!!"

Subheadline: "New York City will be underwater in less than a century, ALGORE says!"

Body: AlGore, the inventor of the Internet and Global Warming, is now warning the world of "Lack-of-Sponge Rise". He is calling for all the leaders of "Coastal Nations" to meet in Havana and hammer out a ban on Sponge diving.

ALGORE, former Vice President who was "Chaded" out of the Presidency, believes a basicTreaty (U.S. stops all Sponge diving, all other "Costal Nations" can buy credits from "Non-Costal Nations" and continue Sponge diving) can be hammered out in a weekend.

Now you're just being silly!

very very very deep
