Yes. But the the amount is very, very small. Somewhat more than 50% of the world's oxygen comes from the top meter or so of the oceans. At least 30%, by the last estimate I remember, comes from forests, rain forests, and similar large-scale O2 producers. Your lawn does indeed contribute to the total O2, but I wouldn't worry about it. On the other hand, if I owned a house & thought could get away with letting the grass grow long, I would. The reasons not to do this include ticks, fleas, and assorted insects. dan davison/theoretical biology/t-10 ms k710/los alamos national laboratory los alamos, nm 875545/dd@lanl.gov (arpa)/dd@lanl.uucp(new)/..cmcl2!lanl!dd -- dan davison/theoretical biology/t-10 ms k710/los alamos national laboratory los alamos, nm 875545/dd@lanl.gov (arpa)/dd@lanl.uucp(new)/..cmcl2!lanl!dd
