None of the above Leo, it is not an eaither or situation.

I am not in the "it isn't happening" camp.

I am in the "it is happening but the reason why is more complicated than just human population growth and industrialization" camp.

Not all of the data supports the theory of human advancement as being the SOLE cause. The main reason such scare tactics are imployed is an attempt to motivate people into supporting a change in how we do things and changing how we do things is not somthing that I am against at all. In fact I am all for it. Lets just not make up a reason for that change when we allready have a perfectly good one that makes better sence as it is.

Do we as a species effect the enviroment around us?, of course we do, we have been since before we had language. Are we the sole perpetrators of global warming? No I do not believe we are alone responsibile, I believe our own contributions are just part of a much larger climatic / solar cycle.

Should we still change how we use rescources and take care of our enviroment? Of course we should, after all, unless we feel like going to other planets , we are stuck here on this one together.

The planet has been both much much warmer and colder at different times during our time upon it and we survived those times with little to no technological inovations at our disposal but we also had a far far exponentialy smaller population back then.

The small changes our climate is making currently if continued along current trends in and of themselves isnt such a big deal alltogether until you add in our ever increasing populations rescouce demands vs the dwindeling unrenewable rescource supply, and when you factor that in then we are going to be in a very very bad pickle soon enough.

But then even if the climate stops changing along current trends, we are still going to have a problem if we dont change sooner rather than later.
