I saw that show too, Poetry. I couldn’t help but think of all the trees we cut down since we came to America. That might have something to do with CO2 levels. I’m a self employed gardener living in a predominantly agricultural county bordered by the Sassafras and Chester rivers and the Chesapeake bay. Some of the longest continually farmed land in the country. The same population as at the end of the civil war. So, yea, we depend on Mother Nature to get by around here. Let it grow. Happy Earth Day.
