Not only are we faced with more and more carbon dioxide in the atmosphere each year, but with global warming resulting from it and acidification of the seas. One might say we are in for calamitous times if we don’t somehow reverse these dangerous headlong trends.

We have a lot of them right here in our own backyard.
