Positive AND negative effects of going green?

I think you're grasping at straws. Yes everything has a good and bad side. Take explosives for example. It can kill people. It has killed people, but it's used to make was for roads and in special effects and fireworks. It has two sides. Green living is the same, but overall, it's a good thing and necessary to a healthy and sustainable society. Don't even get me into the bad side of non-sustainable living. What you will find will make you throw up. It's disgusting and despicable.
