Sadly and unluckily, yes,
yes I have. Many neighbors dump their chips and juice boxes carelessly, as if
the ground, as if the precious ground, was a wasteland! Not many, but some
ride cars to places that you can go by foot, bike, roller skates, skateboard,
and many other equipments that can be used to get there! I have also seen a ton
of people fixing their cars outside and then dumping the old oil out! And then
do they know that the oil gets evaporated? And then it affects our fresh air severely?
And did they also know that all that "unuseful" oil can be used for
something helpful? From personal experience, I used a small amount of old and
unwanted car oil to actually reduce and even remove filthy rust from my bicycle.
Most neighbors don't think before they act. Something they and I must always do
before they act!
