I think many people who are getting their knickers in a knot over this whole climate change thing dont really understand the different sectors of the environmental movement so i will try and clear things up now here goes:
1) Pollution = Any human addition to the earths environment of harmful products - This is a real problem and can come in the solid, liquid, and gaseous forms. Think chimneys spewing toxic gases into the air, factories releasing dangerous chemicals into the water, and rubbish trucks dumping toxic waste in landfill.
2) Extraction = Any human removal from the earths environment of limited products - This is a real problem and can come in the energy and materialistic sectors. Think Earth having a finite amount of feed-stock for non renewable energy sources, and Earth having a finite amount of reserves for minerals and metals.
3) Climate change = The periodic (on a geological time scale) change of the earths weather systems, temperature, rainfall, and all the rest of that fun stuff. Most scientists agree that this particular climate cycle is going to be more serious than previous climate cycles due to human beings pumping more carbon into the air.
Have i missed anything?
