Or if you've "signed" social agreements not to bring harm to people who care about you then it's unethical because your actions could cause harship to those people. Think children, spouses, friends, family -- folks who are going to have to pick things up if/when you lose control of whatever it is that you're doing to and with your self.

There's a lot showing that epigenetics carry your poor life choices on to your children. So, though the DNA itself may not be changed, there very well may be an inheritable genetic result of drug use.

There are foolish places in the world that have water piped into the desert. See Las Vegas, for instance. I'd much rather see Vegas producing cheap, renewable gasoline with that water that used to be known as the Colorado River.

Offset this by using Solar Panels which cause a net cooling effect on the atmosphere and you get back close to being neutral. I'm not sure what it would take to create a true balance, but it'd be a good start.

Last I checked:
latter/latr/
Adjective:
Situated or occurring nearer to the end of something than to the beginning.
Belonging to the final stages of something.

Yeah, though I am pedantic, I fear no evil...

Leash laws prevent letting them slip, though.

I endorse this approach. I like community bug-hunting.

Unfortunately, you're only half right. You have to take the listener into account.
I spend quite a bit of time in the queer community and hearing someone refer to something as being "totally gay" is positive. Both speaker and listener feel it's a good thing for something to be gay.
I could take that term off to my tech job and say that our new environment is totally gay and...well...I'd have to go and have a talk with HR about what's appropriate because, though I intended the statement to be as positive as the other community means it, my listeners didn't.
I never knew that "spade" was also a potentially racist word until someone pointed it out to me. I wasn't being racist but I was definitely making my listeners uncomfortable with my potentially racist remark.

tldr; Communication is a bi-directional and the listeners connotations matter just as much (or more) as the speakers.

I am the pedantichrist!

Only in calculating their budgets.

I have to disagree. Though the listed items for the most part deal with things that are sourced from external stimuli, the act of cogitating on them for a while does NOT have to be external. Once you've read a piece of poetry or literature, heard a song or held a political discussion, you can go back and reflect on that. Distracting oneself with Angry Birds (the apparent favourite from reading so far) can prevent reflection on past experience or taking the time to extract meaning or insight from previous stimuli. That being the case, I'm guilty of hovering over my OpenSudoku while stuck at the DMV, so what do I know?

Those of us with extensible browsers can do better than DoNotTrack, which relies on the good nature of the site you visit.
Try getting a browser plugin to modify your headers and set it to filter or change your Referer header (I like to set mine to something snarky, in case the site I'm visiting is watching).
I've yet to have anything noticeable break as a result of this little hack.
Steps 2 and 3? Disable Cookies and Javascript. Of course, that can take quite a bit of fun and functionality out of HTTP services, but it's your privacy.

Or Wikipedia could join CACert.org.

AC, I wish I knew who you were so I could praise you properly. Instead, I can just say, "Fuck Yes."

If I've read this article correctly, the math shows that it's possible. The downside being the energy required to generate the field in the first place.
