What type of transportation uses water?

Answer 1

Boats, Ships, are all harmful to our earth. Each time we are traveling on these boats, oils and toxins are released into the oceans harming our fish, killing them more and more each day. This is also polluting our water that we will soon drink, and if not treated properly, we could die from drinking toxic wastes that we put into our own waters.

The question is very vague, but to name a few transportation types that "USE" Water: boats, ships and submersible craft or course. But "that use water" is a broad scope. Steam Locomotives use water to make steam to run pistons. Cars and other vehicles using a combustion engine often use water to run cooler. If this doesn't answer your question, please be more specific and we'll see where we go then.

As for the first responder; although most watercraft release petroleum byproducts they do so in minuscule, trace amounts. We're talking .001 parts per million contaminants to sea water. That's 1/1000Th gallon of oil per 1 million gallons of sea water. Does it hurt the environment? A little bit, but not enough to outweigh the benefits of sea transportation versus the little damage it does. Will it kill the oceans? Hell NO, because all the crap that we put in the air that rains into the ocean and all the other water sources will do it first!
