The worlds population is exploding and not many are potty trained. Here is some encouraging news for your kids. Today's population is around 7 billion and by year 2050 it will be 10.5 billion that's an increase of 50% in 37 years. Many Campgrounds will be residential areas and when you are camping you might need to share food with your neighbors. Farmland will be reduced due to population growth, residential and commercial info restructure. So less farmland than we have today to feed 50% more people, could be a famine.
So the long way of saying it will only get worse so let's enjoy the peace in quiet while we can.
