Easily. Most crops are used for animal feed. For example, 90% of soy grown in the US is sold as animal feed, and all of the soy grown in the Amazon is being sold to the US as animal feed. Not to mention crops like alfalfa that are useless for anything except animal feed that we could swap out for crops humans could eat. We could easily feed the entire world’s population with our current crops.
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?”
More than 70% of all crop land is used for animal feed which makes up about 10-15% of the diets. So yes, there is more than enough land. Many multiple times even. Same goes for water usage.
We could just eat less fish or stop eating fish completely. There’s plenty of crops on land to feed everyone.
At some point we all gotta start farming bugs. Most prevalent protein source on the planet.
Would there be enough land for the crops once everyone went crop eater, is the more important question, I think.
