With carbon dioxide levels rising to the highest levels that have been seen in recorded history, it is likely that this trend will only increase. The cause of these deaths by emissions are cancer and heart disease, two of the most deadly killers in this modern age.wo of the main nutrients affected by higher levels of carbon dioxide are zinc and iron, nutrients for which about 2 billion people on Earth are already deficient (that comes out to almost 30% of the global population).
The discovery of mercury as an element was in the 18th century. Incidentally, at about the same time, also 3000 years ago, the Sumerians discovered the planet Mercury.
