negative and pulls more c02 out of the environment than the electricity puts back in but in order to feed the world, these algae farms would need to be placed around the globe. not everyone is top of the volcano. the system itself is also always carbon negative because we take in c02, carbon negative because we take in co2, we fix it in biomass and c02, we fix it in biomass and breathe out oxygen. but co2, we fix it in biomass and breathe out oxygen.- co2, we fix it in biomass and breathe out oxygen. but if you are havin: to breathe out oxygen. but if you are having to use breathe out oxygen. but if you are having to use electricity breathe out oxygen. but if you are having to use electricity that - breathe out oxygen. but if you are having to use electricity that is - having to use electricity that is generated through coal. the system is generating c02 as well. yes. is generating co2 as well. yes, es. and is generating co2 as well. yes, yes- and then is generating co2 as wel
