Just because it happens in nature doesn't mean it's OK for us to make it happen in more places. If you've ever been to the beach around that oil seep you'd know it sucks to get the tar on you or your surfboard. We don't need more.
And it's also interesting that these companies have been passively capturing the oil from the seeps, which potentially reduces the amount of tar washing up on the shores.
it seems like even without a spill, these things are dangerous to ecologies over the long term. the petroleum industry has negative externalities at every end and throughout it’s operations.
