I know people that are working in carbon sequestration and ethanol production.
Ethics becomes complicated once you realize that surrender is a bad policy. Would you rather than Iran have the ability to produce nuclear weapons while the US doesn't? I know lots of people in the military, and soldiers hate war more than most people. I happen to believe that you can't have peace unless you prepare for war. Some people disagree, but there is no need to get insulting about it.
Some of us were involved in keeping a bad situation from getting a lot worse. Also, I know a lot of people that are working on risk analysis and trying to figure out what happened and how to keep from having it happen again.
I'm trying not to get annoyed here, but some of us are trying to use our skills to make the world a better place and to improve our own lives.
What the heck have you done? What do you want?
