# Could we sequester co2 by dumping forests in deep oceans?

We know that trees are the most efficient "tool" we have to get CO2 out of the air, but the problem is that most of their fixated CO2 will naturally reenter the carbon cycle through decomposition. Would it be possible to remove this carbon by sinking the trees deep underwater (and possibly putting some rocks / sand on them)? How effective would this be, if at all? (I was unable to find any studies on this, if there are please point my to them.)

Update: I found a study regarding wood burial on land, for those interested. This might or might not be easier than under water, are there are any field trials either way? https://cbmjournal.biomedcentral.com/articles/10.1186/1750-0680-3-1

• Effective? Not at all. Transportation alone would require enormous amounts of energy. – Jan Doggen Aug 6 at 13:03
• Where would the many trillions of £ / $come from to finance this mad enterprise? How would we get permission from other countries to chop down their forests? Who would pay for the riot control when outraged environmentalists rioted? Wars are extremely expensive, so who would pay for the wars that ensued when countries with forests we attempted to take tried to defend their territory? How would you console the relatives of the dead? How could any politician who attempted to implement this crazy scheme ever hope to be re-elected? Any answers? – Michael Walsby Aug 6 at 13:26 • "Where would the many trillions of £ /$ come from to finance this mad enterprise?" - I'm not talking costs since this is more about general feasibility. However, if one where serious about co2 removal, it might be one of the cheaper methods. And why be so adversarial and assume that countries need to be invaded (lol) - maybe such a scheme might be financed by co2-offsetting and the wood is just bought wholesale. – Quote Aug 6 at 14:12
