Let's say this is true. It doesn't square with the fact that the average life span in North America has increased by 10 years since 1950. Worldwide, it has increased from under 50 years to over 70 years over the past 10 years. So, people may be dying from new or different illnesses, but fewer of them them are dying young. If anything, dying is harder and not easier because there are more cures and life extending treatments today then ever before..
They can be cured or manage the condition, so not necessarily 'dying' as Wiggs stated, but all the toxins, pollution, pesticides, radiation, and other chemicals are not helping and arguably increasing chances of developing illnesses.
Fr example, a person who smokes cigarettes is more likely to get lung cancer. What about the people living in smog filled cities who are constantly breathing fumes from vehicles, factories, etc. ?
In China they have to close school on some days due to the toxic levels of smog.
