I'm not going for global warming because if it is a scientific fact, there's nothing positive about it. Unless with flooding, it could result in ZPG.
ZPG or zero population growth was huge when I was collegiate. Over population would destroy the earth. There were just too many people having too many kids worldwide. So no self-respecting couple would have any more than 2 offspring, resulting in ZPG, of course. And, of course, that was before Roe v Wade, thus making ZPG out of date, since if we want to abort because, well because of anything, we can legally. Nothing positive there, so ZPG is out.
How about Earth Day? That was also begun when I was in college, and I attended the first celebration of it just outside the Student Union. We were celebrating taking care of the earth. We were into conservation of our natural resources. But then we polluted Lake Erie so bad, that a spelling change was necessary--Lake Eerie. We also had no respect for the land at a little love concert we called, well, you know, Woodstock, the one in New York. But we littered the landscape with plastic bags, and screwed up the ozone layer. Well, we're still celebrating Earth Day, but we use our cell phones to inform others about it, while we deprive the gorilla population their land because we need a valuable ore necessary for production of the cell phone. So we take it. Thus, while the concept is good, the practice isn't.
See what I mean? The green, that's good. The plus, that's good. Put them together and you get Plus Green. Or Green Positive. PG or GP. I still don't know what it stands for or what it should represent. But it's an idea whose time has come.
