Your Garden Rocks and It Offsets Carbon Dioxide, too!March 09, 2009
The headline that caught my attention this morning (after the cartoon that celebrates the arrival of mud season) reads, Rocks Found that Could Store Greenhouse Gas. Mostly, the article discusses deposits of stone in the US that have the potential to store something like 500 years of US carbon dioxide production. That’s pretty cool!
What’s additionally cool is that they’re working on studies of common volcanic basalt, which is mentioned at the end of the same article. Here in Seattle basalt is used to create rock walls everywhere. Too, it’s the cool stone you see used in a variety of stone column waterfeatures. Personally, I’m not a big fan of basalt for rock walls for a number of reasons. But, I do like it used in landscapes for waterfeatures. The natural birdbath shapes and the columnar forms are beautiful. In my own garden, along with many other forms of natural stone, I added a small dish stone years ago. It collects water, attracts birds and provides a focal point from one of my patios and out my dining room window.
Is it sequestering carbon dioxide? I sure hope so ’cause it isn’t going anywhere anytime soon and besides sitting there looking pretty and acting as a bird spa, locking up carbon would help this lovely stone start eradicating the saying, “dumb as a rock.” If it can react with the carbon dioxide and draw it out of the atmosphere to help the planet live another day, I consider that pretty darn smart!
