The problem with "global population growth rates" is only in the developing world. As a society develops, birth rate naturally goes down. Right now Japan is facing a top-heavy population due to declining birth rate, and Europe is also below the replacement rate. I think the US is about flat, but because of immigration. The reason is that as infant mortality goes down (less need for "spare" kids), and as lifestyle options increase, children turn from an asset into a liability. Child labor laws also help reduce the value of a large family, and having children at a later age reduces the replacement rate.
You not having kids isn't going to help the planet. People in India and China having fewer kids makes a much bigger difference.

The contractor made changes to save money. Only in this case they got the PE to sign off on their changes without evaluating them.
The other day I needed to open a Visio document. I had created it a few months ago, before my old XP PC got refreshed with a Win 7 box. For some reason, while it still had Office 2007, it was missing Visio. Even worse, it wanted to open IE, which wanted to use an ActiveX viewer plugin... which proceeded to turn the line art into a bitmap when printing to PDF.
So I downloaded OO. No Visio for you! (This was actually the point at which I tried the ActiveX viewer.) Then I decided to check if Libre Office could handle it. Holy crap, yes, it opened it like a native document.
Then I made sure to save a PDF version of my document just in case someone else wanted to see it later.
I've been using the H&R block off-line software for the past few years, OS X version. The main reason is because they are NOT the #1 in that market, so they won't get cocky like Turbo Tax. And I'm in Texas, so the basic basic version. You also get 5 e-files included for the price, so I got my mom to use it a couple of times.
I get it for $15 at Fry's in January because even though they mail me a new disc every year, the amount they want to activate that online costs more than buying it at Fry's (like ten bucks or so more). At least they sent a cardboard sleeve mailer this time instead of a full snap case, to save postage on something I won't be using anyhow.
