Really fun video about sperm whales. I feel like their natural iron cycling and phytoplankton boosting properties, and the fact that we nearly hunted them to extinction, should be more than enough justification to pursue iron seeding for geo engineering purposes, guilt free. There's a massive iron deficit in our oceans and it's probably one of the largest causes of runaway CO2 and global climate change.
