I recently read about heavy metal eating worms in India which can remove toxins from soils. I found this to be fascinating and wonder if anyone out there has additional information about this cool idea. The project in India, overseen by Dr. Suneet Dabke, used 300,000 regular earthworms to reduce the heavy metals in the test soils by 60% in one year! That is impressive.
What I don’t understand is how that takes the metals out of the larger “Earth system.” According to the study, once the worms have completed their job, they are sifted from the soil and burned. First of all, that seems a bit mean since the worms had worked so hard for us! Secondly, I imagine the heavy metals would be released into the air during the burning process. This is where I am hopeful that you may have some insight for me. I am curious and want to learn more.
