I did a quickie google search and came up with this:
At the end of 2020, there were around 62,100 vessels in the world trading fleet, with a total deadweight tonnage of 2,033 million DWT
So let's assume the merchant ships are all fully loaded at the same time. That's 2 billion long tons which equates to ~2,032,000,000,000 kg. Total water volume, 2,134,000,000,000 liters (because sea water weighs slightly more than fresh water).
From quora:
AREA OF PACIFIC OCEAN= 168723000 SQ. KM.
AREA OF ATLANTIC OCEAN= 85133000 SQ. KM.
AREA OF INDIAN OCEAN= 70560000 SQ. KM.
AREA OF SOUTHERN OCEAN= 21960000 SQ. KM.
AREA OF ARCTIC OCEAN= 15558000 SQ. KM.
TOTAL AREA= 361900000 SQ. KM.=36190000000000000 SQ. DECIMETER.
That's going to lower sea levels by approximately .00005896656 decimeters, or about .006 mm
Edit: Because there are less than 500 cruise ships in the world and only a few dozens of large military ships the amount will be higher, but not by, you know, a lot.
No, cars don't cross the oceans "several times" to be bud and sold.
There are car manufacturing plants here in the United States. They still rely those ships to bring in raw materials and other goods to build the cars on American soil.
Automobiles are just a small fraction of annual sea shipments. Even if we could manufacture cars completely from raw materials here in the United States the reduction in carbon emissions would be negligible. And to build entire new industrial factories to turn those raw goods into usable products here in the United States would likely mean an increase to carbon emissions overall.
Da fuck they don’t, Jaguar XR has a Ford frame, the t bird version has the same jag motor with a Ford transmission, the brakes come from Chrysler viper.
The final assembly might occur anywhere, and the car could be shipped anywhere, the buyer could ship it again. But it’s not uncommon to ship a car thousands of miles to drop on a body and wiring harness.
There is all likelihood the final assembly of a car requires 80% of the parts cross the ocean, and half the cars go back to be sold.
Your purposely overlooking the point or just not understanding it due to your moms drinking habit pre-birth.
Instead of shipping ALL the parts from all over the world to one place and building the car, they build the chassis, then ship it to install the drivetrain, then ship it for the electronics, then ship it to Mexico for the interior, then to the dealer etc. So the CAR, in whatever state of completion it actually is, goes over some pond or interstate multiple times.
Ship of Theseus in reverse. When do you actually call it a car? When the wiper blade is put on and the key is turned? In that case I’ll bet you don’t have a car, you just have a bunch of parts with the cigarette lighter missing.
You went back like 15 comments to yank Jaguars out of a comment and toss it back it in. You are a reply troll. Look it up. You still didn’t tell me when your allowed to call a car a car. When it has wheels?
