Will new tectonic fault system kill the Atlantic?

The dying Mediterranean Sea may have contaminated the Atlantic with a subduction zone. One day, it could help destroy the vast ocean.

Oceans come and go over hundreds of millions of years. New ones are born when continents are ripped apart, allowing hot magma to bubble up and solidify into oceanic crust. They die when continents collide and force oceanic crust back down into the mantle.
