Some Childhood God Questions

Growing up through the eighties and early nineties (I was born in 1974) I was always concerned about our impact on the environment. I mean it was twenty some odd years after Rachel Carson published "Silent Spring", so the message was out there for all those that wanted to see. Of course, being a typical kid, I wanted to see anything and everything I could lay my eyes on. And it was obvious that we were destroying the planet. So some of the questions that I asked on occasion were: Why are we destroying such a beautiful place? And why, if God created it all, is he allowing it to happen? And, also, why if he created us did he program us to do this? You'd think an all-seeing and all-knowing God would know better.
