Don't you pollute the ground by default just doing what you are doing daily?
Don’t everyone pollute by default? Think of all the empty containers and jars of stuff thrown in the trash? Most things are never used up 100%. When you buy oil after you empty it into your vehicle there is still oil clinging inside the bottle. This clinging oil may not be much but even if it were 1/8 of an ounce multiply that by 1,000s or 10s of 1,000s of containers and it can add up to quite a bit, especially if the plastic ever deteriorated away or was damaged and breeched to let the oil escape. Down the road there can be a potential oil slick created in a buried landfill. Not to mention all the engine treatment containers, nail polish, and other chemicals. As much as one might try you more than likely always pollute de factoly whether you like it or not.
