Now ain't that the truth!

Actually, I have mixed feelings about the global warming issues, CO2 and the like. I have absolutely no doubt that it is having an effect. How much is questionable. However, that question is neither here nor there. The fact is that this is the only home we've got. And as Carl Sagan once said "It's the Big Blue Marble of our solar system. There is no place like it. If we crap it up - where we gonna go. We had better figure it out - like the Indians of old before us. Take care of the land and it will take care of you. The old Indians understood this. They were not educated in a traditional sense, but were educated by the wilds themselves, and they understood. Modern man, particularly those with a European heritage, are still heavy oin the consumption and weak on the giving back. That philosophy is going to eventually eat our lunch, dinner and late night snack as well. Like canaries in the mine, the are many animals that are warning us now, that things are not right with the planet. The disappearance of the golden frogs in S. America, The current disappearance of the honey bee. All are indicators of something wrong in the environment.

We had best pay attention, do what we can, and become major stewards of the land.
