I thought ain't it a lot more of lakes on the trees than it use to be...
”The lakes are nature's air indicators. If you want to see if the air is clean where you live, you can check which lichen grows on the trees. If you find beard lichen, the air is probably clean. If you find no lichen at all or only shoe plots, the air is probably polluted.”
I really hope I'm right about that it's more lakes growing on the trees than it uses to do back in the days!
