Would you care to address oil pipeline breaks now? There's been plenty of oil tankers that have wrecked and/or spilled their load of oil. Lithium ion batteries aren't going to have the widespread effect like millions of barrels of oil that get out at about any spill. Oil also spreads a lot, whereas the lithium ion batteries at most would just kind of leech some chemicals into the ocean. I don't think some lithium ion batteries falling into the ocean is some huge environmental disaster compared to all the other ways oil can and does continually spill, aside from an oil well in the ocean.
