there was a great piece on NPR (I’m sorry, I can’t remember which show) talking about an invasive species that is decimating citrus. There have been board meetings btwn companies on the issue. They estimate that citrus will soon be a delicacy. One lemon/orange will cost ~25-30 dollars.
It’s already destroying huge swaths of crops & causing farmers to abandon agriculture. You can tell bc oranges from the grocery store are largely flavorless. Other places in the world hang these huge nets over the crops, but only ONE of this species has to get in to completely ruin it.
