Would there be enough land for the crops once everyone went crop eater
Yes. Even despite absurd levels of agricultural waste (40% of our crops go in the trash, in large part due to poor refrigeration infrastructure, dismal labor conditions, and market price fluctuations killing a harvest season) we end up with enormous vegetable surplus.
Fish, shellfish, and other sea life are still a highly efficient source of protein and other nutrients. Crawfish, for instance, are basically an invasive species byproduct of sugar and rice harvests in the Gulf Coast. There’s little reason not to eat them, given you’re getting them whether you want them or not. Same with mussels and clams, as anyone who has had to clean the underside of a boat can tell you.
But the degree to which pollution and industrial fishing wreck coastal and deep sea habitats absolutely does make it unsustainable long term. We could live to see a future without tuna or swordfish or halibut purely due to our aggressive ecology-wrecking fishing practices. So it’s less a question of “Could we live without fish?” and more a question of “Will we live to see the extinction of fish?”
