Earthworms might be an indicator for soil quality. In a study out of Melbourne, Australia, earthworms were collected from farms that use conventional farming methods including synthetic pesticides and compared to other earthworms that were collected from organic farms. The study used metabolomics which can show how creatures with the same genome might be responding differently to different environments. Worms from conventional farms showed a higher level of metabolites which are associated with stress. Metabolites have, in the past, been high in worms that are exposed to copper and other soil toxins. Dr. Simone Rochfort of Victorian Department of Primary Industries and head of the study suggested that farmers could get a sense of how healthy their soil system is by getting their worms tested.

earthworms quality soil better soil more earthworms present. I have a lot on my property the soil is dark and rich. So i agree if you find a lot of earthworms in your soil, your soil quality is very good.

The hatchery on the Noosa River has been experiencing more and more mutant fish, at a rate which appears to coincide with the expansion of a nearby macadamia nut farm. That farm uses pesticides—carbendazim and endosulfan—which are banned in many countries, and is now completely bordering the hatchery.

Some fishermen in Maine say current environmental regulations inadvertently support large fishing operations, leaving the small ones high and dry. But with CSFs, small scale fisheries win. In addition, many of these small-scale fishermen are looking to their past to address environmental issues. Instead of jumping on the technological treadmill and buying up new equipment to catch fish in order to keep up with the big guys, they're scaling down their technology and using older, tried and true methods that don't cost a fin and a tail to either fishermen or the marine environment.

It's true what our moms said...we are what we eat. In fact, it's truer than they thought. What I eat doesn't just affect me anymore, it affects all of us.
Unfortunately, the story of food can sometimes be complicated. But envirovores help each other out...which is why this blog will be bringing you news, tips, and information about food and the environment every step of the way.
