Get Carbon Positive With Ixpo
I have a tweep (someone I follow on Twitter) who told me about the “Plant a Tree” initiative.  This program plants a tree for every blog or site registered in the program.
Why plant a tree?  Because trees use carbon dioxide and replace it with oxygen in the air.
Still not clear?  Think about this:  visiting a blog uses electricity, and making electricity (to power the servers, computers, etc, as well as the cooling systems) discharges carbon dioxide, having an overall negative impact on the environment.  They’ve figured out that 1 new tree planted for each blog will actually use more carbon dioxide than the blog creates, essentially negating the carbon dioxide effects of the blog on the atmosphere.
I’m not sure how it all works, but I do know enough about science to know that planting a tree is rarely (if ever?) a bad thing.  If my blog is contributing to the mounting carbon dioxide discharge in the world, and I can do something to minimize or even stop contributing all together, then that’s a good thing too.
Ixpo will plant a tree for my blog, just because I added the button to my blog, and told you about it!  Cool, eh?
So, this blog is carbon positive!  It just seemed like the right thing to do!
