Hmmm, I'm not sure where you got the 2% thing but I do know that in many countries of the world we have changed and are using almost all of the available land. The oceans are not exempt either, look at the grand banks, the amount of cod there used to be able to stop ships (sail equiped, not engine equiped) now the cod is on the brink of extinction. Matbe you meant that we occupy 2% of the world with our houses, highways, parking lots, refineries, shopping malls, etc? You couldn't mean our farms, open pit mines, fisheries, wind farms (no offence), etc. 3% of the world (entire world, not just land) is farm land, hell, we use over 350,000 acres of land just for the cultivation of cocain! I know, farm land is good, it is a plant and therefore is part of the ecosystem, the difference is that we take the plant elsewhere, eat it, vacate it, then it goes to some treatment plant and never returned to the soil that made it, it is not a sustainable system. We are changing this planet and we are changing it in a hurry, solar farts or not.
