From "GLOBAL WARMING"  to "CLIMATE CHANGE".  Global warming makes you think it should be getting hotter outside, but it isn't. Unless you live in the desert.  True global warming will melt the ice packs, spilling more cold water into the oceans which will lower the temperature of the water and that will affect the temperature of the air moving off the ocean that creates our weather patterns.  Every thing affects everything.  All of existence is interconnected, from the scale of the entire globe to the micro-ecosystems withing your yard, garden, any little spot of earth.  Even the sand in the desert has more than sand in it.  We (man) cannot help but impact our world and change it, simply because we exist.  One more child is born, and one more mouth breathes out carbon and requires stuff and food and water.  The human impact is unavoidable, so we do what we can to compensate for it.  The human impact can be positive through the practice of reducing our carbon print by growing our own food, staying home more, composting, recycling, reducing, reusing as much as possible.  Start by using cloth diapers, wash them at home, hang them up to dry.  Live withing the cycle of 'usefullness'.  Of course, it does require you stay home long enough to wash and hang out and then take down and fold the diapers.  Personally, I love the chore of hanging clothes out on the line to dry, and then taking them down and folding them.  You experience aroma therapy when you fold line dried laundry.  The sun has an antiseptic (purifying) effect on diapers.  You get fresh air and a sense of doing the right thing for the earth that balances out the new human being that will breathe out carbon all his life.  People need to think more about their choices and take responsibility for them, perhaps compensate for them whenever possible.  That does not mean having no children, it just means raising them smarter.
