I'm just trying to point out a couple of issues in your logic. You cannot multiply wetland. It takes a thousand years to get a 10m deep peat bog and every second of its wet, rotting existence creates CH4. Wetlands offer lots of benefits —nature, water management, etc— but greenhouse gasses really aren't one. More importantly you're only comparing standing volumes of carbon. We extract billions of m³ of lumber out of forests each year. Even the process of growing it, is far better. Methane is being consumed, not created. The overall picture is complex but if we're thinking about things in the short term, farming lumber (and using less concrete, brick) would do far more good than creating wetland.
