Every week, I share something I learned in the previous seven days. I usually find this while I'm putting my weekly newsletter together but somehow it doesn't quite fit!
This week, I learned that scientists have discovered a source of 'dark oxygen' on the floor of the oceans. These are lumps of metal, that generate oxygen into the sea and might mean that we need to change the way that we think about mining the ocean.
Dark oxygen made by deep sea ‘batteries’
The discovery that lumps of metal on the seafloor produce oxygen raises questions over plans to mine the deep ocean.
