As we know, the technological revolution of the 20th century launched discoveries, events and activities that have helped shape the highest standard of living known to mankind. Within the health industry alone, many deadly diseases have been totally eradicated and scientists continue almost daily to announce new breakthroughs that could lead to improved health care. But many challenges to human health still exist.

Today, humans are confronted with a hustle-and-bustle lifestyle unimaginable twenty years ago. While enjoying the highest standard of living ever known to man, humans are dubiously rewarded with increased stress and tension, exposure to life-threatening environmental pollutants, viruses and bacteria previously unknown to scientists. Many of the unintended consequences of the technological revolution adversely affect human health.

For example, antibiotics, one of the wonder drugs of the 20th century, have helped conquer many diseases that previously resulted in death or disablement. We now know, however, that antibiotics have limitations and their, use and misuse has frequently led to ill health.

There also are a number of viruses and bacteria that have developed partial or total resistance to some antibiotics. Further, "wide-spectrum" antibiotics usually don't distinguish between "bad" and "good" bacteria. They kill the good bacteria along with the bad bacteria and this indiscriminate killing of bacteria may be one of the worst side effects of using antibiotics.
