When did I advocate going back to the Stone Age?
All I am saying is that I have yet to see a situation where destroying our immediate environment and adding lots of toxins has not had a negative effect, so it seems reasonable to limit the extent to which we do so whenever we can.
Big difference between unnecessary excess/willful destruction and moderation/good stewardship to keep from destroying our planet.
Not sure I follow you on this one. Give some example of what you are saying becasue your original question was as follows-- "The question was drastic environmental change plus pollution and a positive outcome". I am not saying that we can never change anything, just asking for an actual POSITIVE example of man-made changes that caused pollution and had a long-term positive outcome because I couldn't think of one offhand.
Okay--here is one example--the automobile/truck/truck/boat/aircraft engine. The exhaust from these engines creates emissions that the global warming crowd says will eventually lead to the melting of all the ice caps in the world. Yet, without these engines, we would still be living in the 19th century. A positive outcome from polluting, man made products.
Here is another--oil/coal/nuclear power plants. These contribute all kinds of pollution to our world. Yet, without these we wouldn't be powering air conditioners, computers, refridgerators, tv's, electric vehicles, etc, etc. Again, a positive outcome from polluting, man made products.
Either we go back to the stone age or you realize that most of the stuff you enjoy day in and day out will likely create some kind of negative impact on our environment but the POSITIVE OUTCOME outweighs the negative impact on our environment.
