I Heard that the 10 largest cargoships produce that Same amount of pollution then all cars combined.
Why are there no nuclear powered cargo ships?

There was an attempt, the NS Savannah was a nuclear powered cargo ship that was *heavily* subsidized by the US government
Cargo ships aim to be extremely low cost to operate, limiting crew requirements is one of the biggest goals and the really big ones can run with less than 20 people while moving hundreds of thousands of tons of cargo. Their hull forms and engines are all optimized for fuel efficiency at a relatively low speed (20 knots) and they are by far the most energy efficient form of transportation
Don’t get tripped up by stats about the emissions of the 10 largest ships, those ships are bigger than you can possibly imagine and moving that cargo any other way would result in significantly more emissions. Even trains are significantly more polluting than a large ship, trucks are ludicrously inefficient compared to water shipping
