" Let them live a bad lifestyle...let them get fat, lazy, unhealthy, and sick..."

What it really comes down to is this: you can't make people do anything they don't want to do. If you accept that fact, you may live a happier life.

Everything wrong with people is from environmental pollution?

No, the food we eat is safer now than it ever has been. In the past, food spoiled because of poor refrigeration. Until the 1930s we still had ice boxes in cities and damp canvass boxes in the rural areas.

Water? In years gone by, wells were unfiltered and people got whatever amount of lead, arsenic and other minerals that happened to be dissolved in the water. Also no cholorination to kill microbes.

Air pollution? Maybe, but it is not responsible for all of man's ills. Besides, people out here in the rural boonies have exactly the same problems and ailment as everyone else.

Now is a great time to live except for one problem: people. There are too many people and too many of them are violent and antisocial.
