Carbon austerity is a political and human-nature non-starter. Kelp forests and phytoplankton blooms across expanses of the ocean are the only viable alternative to capture and sequester (by sinking) enormous quantities of carbon to get us to net carbon negative faster than anything else. This will require robots to help us seed and farm huge areas of the ocean.
