Not sure if it's a time to cry about the loss of a bush of roses when the forests are burning. Any natural iron supplementation like blowing the dust from Sahara or a river carrying out to the ocean waters full of red soil should be causing similar effects. Granted, rivers are likely carry other nutrients, often in excess, but this also does disrupt what grows or not in the surrounding areas.

Iron fertilization may still be pointless since the effectiveness is being debated afaik. On the other hand if it does work well for a competitive price compared to other methods, I would rather have a fish in the middle of the ocean full of algal neurotoxins and lower global temperature than the same fish cooked. No need to at it though.
