Darin,
How much bar oil have you used over the years? 20 gallons, 50 gallons, 100 gallons???
Now, let's assume you were to take that same amount of oil and just dump it out on the ground. Are you polluting?
I realize when you use a saw, the oil is released slowly over a large area, but does that make it OK?
How much bar oil is used nationwide? ALL OF IT ends up in the environment.
You're, right. Your little bar oil is not going to make a difference. But that attitude is part of the problem. When you multiply your little bit of oil by thousands or millions of users, there IS a problem. You contradict yourself when you say that every little bit helps, but you refuse to do your little bit. "If you're not part of the solution, you're part of the problem."
