I believe the Pope mentioned this just recently…about taking care of this earth.
The church doesn’t have a complete list of sins. And nobody makes up a sin…it is either right or wrong or neutral in everything we do.
I know on the motor oil it says right on the label that this can cause cancer by coming into contact with it. And I’m quite sure that many chemicals could also do the same.
Sometimes these items have mercury in them and if not disposed of properly can cause a number of medical problems.
I bought a bag of grub worm killer for my lawn a few years ago and on the label it said to handle with the utmost care and to keep pets and people off the lawn for a few days. It said to cover the entire body before using and to wash exposed skin about three times. Then it listed the illnesses it could cause. I gave it to the chemical disposal unit without using it on my lawn.
Another fellow a block from me had a lawn fertilizing business which his two sons helped him with. He quit the business because the chems caused permanent damage to one of his son’s knees and did something else to his other son.
Most of the plastic grocery bags do break down in the ground and are recycled by mother nature. But I don’t know what the chemical breakdown does to the ground and water supply.
I didn’t bring this up to make anyone’s life more miserable, but to make other people’s lives after us more safe and healthy. What we don’t know does hurt us. And charity dictates that we care.
