Can we modify the genes of plants so that they can absorb more carbon dioxide and grow faster? If happens, it will both create more biomass and reduce green house gas. Thank you.

I think so. Plants have a couple carbon fixation pathways. C3, C4 and CAM are the main pathways, each with different characteristics. There are many genes and enzymes in each pathway so upregulating/overexpressing some of them will make more carbon be processed into their biomass (most of a plant's biomass is from the air, not nutrients/water). Couple problems with this is that the plant may grow too fast for its structural features to support the weight, especially if they're not developing fast enough or absorbing enough nutrients/water to keep up with the increased C.

Whoa, did my answer contribute to the podcast? Pretty cool if it did. If not, I'm glad I wasn't incorrect.
