It’s incredible that we’re still learning new things
When did trees get lungs?

When they got leaves. I used to do tree work. We never did chemical injections on windy days, because the stoma would close down and transpiration rates slowed to a crawl.
Amazing. One person asks a really good question, another comes up with the really good answer. I love it!
