-One big reason Chile is an excellent choice is that it is in the southern hemisphere. 95% of the world’s pollution is created in the northern hemisphere. Air from the northern hemisphere virtually doesn't mix with the southern hemisphere. 85% of the world’s rainforests are in the southern hemisphere (Chile has the world’s largest temperate rain forest). Rain forests are natural pollution filters. 96% of storm related deaths are in the northern hemisphere. Life expectancy is higher in the southern hemisphere compared to the northern hemisphere.
Planetary atmospheric airflow follows a simple pattern. Cold air from the poles travels to the equator, heats up along the way, and then circulates back to the pole of origin. Very little air from the northern hemisphere enters the southern hemisphere and air from the south stays in the south.
Now consider this, – all pollution and airborne radiation poison from, a) the past sixty years of worldwide above ground nuclear testing, b) the two atomic bombs dropped on Japan, c) Chernobyl, Three Mile Island and other nuclear accidents, d) the steady emission of radiation and related toxins from nuclear power plants, e) the exhaust of massive amounts of depleted uranium dumped on Iraq over the last fifteen years, in Afghanistan, in parts of northern Africa today, from training exercises conducted on U.S. domestic military bases, and very likely soon to be dumped on Iran, f) the radiation fallout from Japan’s nuclear reactor meltdown cause by the 2011 tsunami and, g) all the industrial toxic pollution from every nasty source imaginable, – coal, gas and oil burning, chemical manufacturing, factory farming of animals, spraying of agricultural crops, car and airplane exhaust, heavy exhaust from the launching of space-bound craft, etc., etc. – stays in it’s hemisphere of origin!
Now look at a map of the world. Note that nearly all major industrialized nations lie above the equator, – United States, Europe, India, China, Japan, Korea, Taiwan, Hong Kong, Canada, Russia, and most of Africa. The few exceptions would be Australia, South Africa, Chile and Argentina, and they are relatively very light in the production of these kinds of pollution.
Why is this important? Well, for starters, there are now tens of thousands of man-made airborne chemicals in the atmosphere, most of them, if not all of them, harmful to living organisms (i.e. you). This is considered by many to be one of the leading, if not the leading, contributor to the explosive rise in chronic disease in the United States and most of the northern hemisphere. Another major contributor to disease is food grown in depleted and polluted topsoil covered with herbicides, pesticides, fungicides and petrochemical fertilizers. If you aren’t eating it directly, then the animals that your are eating are eating it! The heaviest of these nasty airborne toxins settle down to the ground thereby polluting land, rivers, lakes and streams. You breathe them, you eat and drink them, and you bathe your bodies in them.
On map: yellow, green and orange red are very high Polluted areas.
