I was a little worried by the following quote:
> New farms are being built in polluted areas like Bridgeport and the Bronx River in order to soak up the nitrogen and carbon, pull out heavy metals, and re-build reefs.
They're pulling out the heavy metals. Where do those heavy metals go? Into the food? I limit my intake of certain foods because of their heavy metal contents; do I have to do the same for their seaweeds?
- icefo 11y agoHe says that just after your quote: "Instead of harvesting food, these farms harvest ecosystem services." That means they don't sell the production
- mioelnir 11y agoHe also commented on it: > It’s a good point. We have two types of farms: those that we place in pristine waters that are tested weekly and those that grow in polluted water. These “pollution farms” like in the Bronx river, farm ecosystem services, with none of the crops going into the food system. Key is traceability of our crops.
- meric 11y agoHmm, they could if it's to make ethanol!
- goda90 11y agoI wonder if it'd require extra processing to make sure heavy metals aren't left in the ethanol or if the typical production methods already leave that stuff out.
- bradleyjg 11y agoDistillation should have no problem dealing with heavy metals. Other nasty things though are azeotropic with either water or ethanol and would have to be accounted for if you wanted to make drinkable vodka. Contaminants are less of a concern if you are looking to make fuel rather than booze.
