Do you think some people would act better if we had less dangerous gasses in the atmosphere?

Since we are all exposed to the same gasses in the atmosphere that is the issue. If people were brought up correctly and taught kindness, manners, compassion, caring, instead of gimme gimme gimme the would would be a better place.

The truth is, people would still have at least questionable behavior, because no signs point that the gases in the lower troposphere (which is where we live) are noxious enough to cause the Earth to be uninhabitable. There is cause for some concern that greenhouse gases are building up in the atmosphere and that the ozone layer is disintegrating, because it's nothing so serious as to cause people to have malignant behavior, as that is a personal decision.
