happy arbor day

i heard on npr today that it's officially arbor day, but just did a moment of research + turns out yesterday was arbor day in some states (http://www.arbor-day.net/arbor-day-state-dates.htm) . must have been a rerun. regardless, it seemed like a nice reminder to pay homage to (+even plant!) our lovely tree speesees, which absorb carbon dioxide + help to keep our planet cool (a single mature tree can absorb carbon dioxide at a rate of 48 lbs./year + release enough oxygen back into the atmosphere to support 2 human beings). now that's something to celebrate!
