Is there a more unsafe way to cut down a tree?

Yes, there is.
Cut the whole thing down at the base.

Natural selection

I'm pretty sure throwing the chainsaw at it Is more dangerous.

Blowing it up with a nuke would be pretty unsafe.

Why women live longer than men

Trying to cut it down while in free fall would be pretty bad

Throwing the tools you used that you're currently not using to the floor, then attempting to bodyslam down to the ground to get off the tree.

Yeah but it involves a flamethrower and a jar of mayo.

Well, the ladders could be wood and on fire.
