This happens along the coastline around America quietly many times a year. Generally the outflow pipes are 1-2 miles offshore so if you aren't in a boat you don't see it, but as a sailor I see it two or three times a year in my home waters. This is why I always scoff at people who talk about MPG or global warming or anything else - we don't even separate storm run off from sewage in this country because a lot of towns saved some money by running one set of pipes - why are you worrying about possible effects of CO2 when there are massive effects happening from something we have the technology to solve today.
One thing that really pisses me off is people using petrol-powered leaf blowers. They are loud and obnoxious, and incredibly wasteful. Whatever happened to the simple broom? To me, the leaf blower is emblematic of this issue. Nobody really cares enough to actually do anything about the insane wastefulness of our society. (And I include myself in that - I utilise way more resources than I really need. At least I don't own a car.)
Your second point is a separate issue - it's more practical to get people to fix the things that can be fixed before asking them to change the way they live and go back to this unrealistic ideal world of no machinery etc.
When you consider that so many people (in Sydney, where I live) commute to work on their own in their cars, and that every 30 of those cars could be replaced with one bus, you can only conclude that it's madness.
Similarly that we're still using incandescent bulbs. Or that many office buildings leave their lights on 24 hours a day. Or that people here run air conditioners 6 months of the year (we are not living in the tropics - I'd say there's probably 10 days a year here where aircon is necessary for any healthy adult - obv the sick or the elderly are another story).
Everywhere you look there are gross inefficiencies, things that could be fixed with a little planning, expenditure, collaboration, and compromise. It saddens me that we seem to be too selfish and disorganised.
The difference between a car and a bus to me is the difference between the internet and cable television. With the former, you get what you want when you want it. With the latter, you have to go along with the group and rely on others to decide for you.
When we all send our money into one big pool, and then have to grovel and beg to get it back from bureaucrats, we start to resent our neighbors.
I'm somehow reminded of the homemade submarine in 2007: http://www.nytimes.com/2007/08/04/arts/design/04voya.html
my first thought: i wonder if someone has already taken them....quietly....
What other way would there be? The line of "officials" who've decided your find should be theirs would stretch around a NYC block. Secrecy is the silver perl of salvage.
Good little article that has made me think about what might be lurking, hiding, or waiting in a waterway closer to my home.
