And we all have the responsibility not to be flinging dirty old used waste oil around in the woods.
The past was the past, and hopefully, just hopefully , we can we learn something from it , and some of the new ways that are available around us.
I guess we all have our own versions of what we think is right.
In my opinion? Worrying about the little bit of oil that gets flung off my bar in my woods? Does not even amount to a pimple on a flea's private parts.
It's in so little concentration, it breaks down fairly quickly. Some winds up in the wood I burn.
I worry a lot more about all the farms in my area using tons of petro-based fertilizers, herbicides,and insecticides every year.
Do you eat any food bought from a store? Chances are -you are supporting modern agriculture that relies almost 100% on petroleum products - that get dumped into the ground and spit into the air and trucked using diesel fuel and refrigerated using coal-generated-electricity.
Now, if I take all my waste oil to a local "proper" dumping place, it will get burned to make heat - locally. So, OK, now it will be turned into various chemicals and go into our air.
I don't fly. Note that air-travel is huge pollutant. I heat my house and barn 100% with my own firewood from my own woods. No oil or propane or natural gas being burned here. I am using a renewable resource to heat my home and barn and all my hot water. My house and barn are on 100% solar electric. We grow most of our own food and mostly organically (but we have to cheat a little).
So yeah, I cause some pollution - but I'm willing to bet I create a heck of lot less then most people.
I'd like to see some facts and figures how much pollution and waste takes place manufacturing "clean" bar oils. I suspect the record is far from perfect.
