I like your comment and the honest answer is I don’t know, but I see no problems with dumping plastic on the ground, vs in the ocean. But some observations on your comment. Is plastic, that was never in the atmosphere (for millions of years anyway), really a carbon sink? It seems that trough its entire lifecycle it never goes into the atmosphere. Also, if you burn plastic you’re displacing oil that wouldn’t otherwise be burned. Oil that is never extracted. And don’t forget that it takes a lot of energy to extract oil, so burning plastic reduces CO2 emissions globally somewhat. Also, I’m skeptical about the practicality of using landfills to create geological treasures for mankind 100k years from now. The problem with it is that I feel that it is wishful thinking that placates our conscience. It’s easy to imagine yourself living “sustainably” in geological time scales. It’s hard to live sustainably in 1000 year timescales.
