Why are we talking about ferns and duckweed? It is the same reason wildlife conservation efforts tend to involve talking about the "charismatic megafauna"?
We would do well to remember that a full 70% of plant-based carbon sequestration takes place in the ocean (you know, 70% of Earth's surface), not inland, and is done by phytoplankton.
- elihu 4y agoI think all these approaches should be looked at. It's not obvious to me that farming algae to sequester carbon would be cheaper/easier per ton of CO2 removed than farming duckweed or azolla.
- steve_adams_86 4y agoThis doesn’t necessarily ignore or exclude utilizing the ocean, though. We should be aiming to do both. The ocean is harder to control - at least with inland controlled experiments we can get a sense of what’s possible and how it can scale. With the ocean it seems our goal would be to simply let it do what it does best, and stop getting in its way. They seem like different endeavours.
