Did you know that I wrecked into a golf course with my friend's dad's car?
Is there a reason why you wrecked the golf course and your friend's dad's car?
I was drunk and I didn't care what I did.
Driving drunk can be reckless behavior to others around you and is something that you should avoid doing. You caused a lot of property damage on purpose to both to the golf course and the car, which is not correct. It is important that you take responsibility when it comes to drinking and perhaps get professional help about it since it can lead to significant health and legal problems.
Did it hurt the environment?
Yes, it very well could have. Driving around recklessly is dangerous and incorrect for all sorts of things, and especially you as the person driving. You could have died.
