A man trimming a tree in America learned the dangers of messing with Mother Nature the hard way.
In a new YouTube video, the man is seen at the top of a ladder yelling, "I don't want to hit anybody, is everybody good?"
He then cuts a branch and as it starts to fall it swings back towards him and throws him off the ladder onto the ground.
A woman is heard screaming "911 or not?"
She then runs over to the man.
YouTube user Kurt Stepp posted the video on the social networking site and captioned it: "My coworker cuts down a tree and the tree is not very happy about it."
The video has been viewed over 478,000 times and users have left comments advising Kurt's co-worker how he should have cut down the tree.
One wrote: "Wow. Seriously, your coworker is not going to survive for very long if he doesn't start:
1. Roping himself off at 15-feet heights.
2. Not standing on the very top rung of a barely-secured ladder
3. Making a bottom cut first
4. Not trying to cut above his own height, and, for f**k's sake
5. Not trying to use a chainsaw one-handed"
Another wrote: "You should always cut from a higher altitude from the branch, you should be looking down at it not up."
Kurt later confirmed that his coworker escaped without serious injury.
