The World Health Organization (WHO) painted a grim picture of the future by predicting more deaths and diseases in 2030. While WHO's reputation may not be at par with that of Nostradamus, it serves as a warning to people who'd take the brunt of the fearless forecast: smokers.

The saying "Smoking Kills" has never stopped cigarette-loving individuals from inhaling nicotine. And if they don't kick the habit, the smokers' population will eventually drop. If the WHO's prediction is accurate,  1/10 of all deaths worldwide will be due to smoking.

The next 25 years will also see the increase of AIDS-related deaths. The number will soar to 6.5 million come 2030.  Smoking and AIDS will be joined by heart attack, stroke, pneumonia, HIV and pulmonary diseases to round out the list of deadly killers of 2030.

It's a grim scenario but it's something that can be prevented as countries become prosperous. In general, as countries begin to prosper, they can afford to set up a better health system (e.g. better hygiene and vaccination measures).
