I bet an average lawn generates more oxygen & sequestures more carbon than 30 trees. It just grows so much faster.

  You can't be serious. The leaf surface of a lawn is much less than that of a tree. And there is zero sequestration of CO2, because all that cut grass is either burnt or turned into compost the next year. With a tree, there's at least a chance the wood is used for some decades.

    At least in my area, that's not how it works. Much of the cut grass goes to the dump, where it's buried anaerobically. That's almost perfect carbon sequestration.

    I wonder how much biomass a tree grows throughout a year? Seems grass would be more as it just keeps turning air into leaves nonstop. Just picturing all those piles of composted grass compared to the pile of leaves raked up in fall...
