Hopefully they planted some trees to offset their carbon expenditure. It would be nice if they stayed home; diverted the money from the trip and simply planted some trees.

I'm starting a couple trees indoors for the winter (two pomegranates and a drought tolerant lemon and tangerine). If we all plant some trees (suitable for one's locale), and tend to them until fruition; we will accomplish more then thousands of delegates.

Tldr: Squirrels combat climate change; squirrely flying around the world in jets does not.

Edit: I should add drought tolerant citrus is quite the misnomer. That being said, I have recently found a six inch diameter four ft tall Meyer lemon and a similar stature tangerine. The best part of this discovery is that they were found in abandoned farmland with no irrigation for three years.

Hoping to get a few growing and then start squirrely tossing seeds in barren environments. Nature will find a way, it's up to us to follow it.
