I found this by accident and thought it was pretty interesting.
I'm going to link a couple websites instead of trying to explain it all out in detail.. because a) I don't have much time on here and b) its a little too complicated for me to do that lol. Long story short, each visitor to a blog or website equals out to a certain amount of carbon dioxide emissions.
Yes, the first link does link to the second lol. For obvious reasons. I like its explanation though, was very easy to read and verified the other for me.
So what can you do? If you haven't already read those sites, what they're asking is just for you to write a blog post like this & add a badge to your blog, send an email with your link, and they will plant a tree. Easy enough.
This is a pretty basic schedule here, just to help me out w/ posts and avoiding ruts. I put family on one day, but little updates will probably end up doubling other posts on other days too because, well, they're the main focus of the blog to begin with lol. This may change as time goes on too, adjust as needed.
