Nothing underground generates oxygen, but moving the roads from above to underground gives more “it’s free real estate” to grow grass and trees, like in the second photo, which generates oxygen and stores carbon. It’s not the best thing like suppressing the cars all together, but it’s better than the first picture.
I think it’s better from a polluting point.
