I found the most beautiful spot by the creek to paint. Then I poured my left over paint into the creek after I finished my project
Oh you shouldn't have done that. Why would you dispose of paint in a waterway?
Because it's a big city and a little paint into a creek won't hurt.
Yes, but if everyone did that, we wouldn't have any clean water for drinking and growing crops. It's not only morally wrong, it's also illegal.
It's not wrong as long as it's ultralight paint.
No, it doesn't matter paint is still hazardous. There are recycling programs you can take paint to the next time you have paint to get rid of. That keeps it out of the waterways.
