Since the topic of the week is conspiracy theories, here's one that I've had re-iterated at me a few times. Supposedly these white stripes after airplanes is created by airplanes releasing biological or chemical agents on a global scale for various purposes.
One site claims that this is causing many forms of radiation to rain down in some areas:
Ionization of these sprayed particles also causes many forms of radiation to rain down upon the as yet unsuspecting populace of the world, as well as lensing programs to dehydrate land and dry up water sources. The first lie of the NWO animals is that a shield is needed because the atmosphere has been depleted -- it is too bad that THEY themselves can now deplete the atmosphere at any time and thus CREATE THAT NEED.
From one site:
This whole chemtrail issue is related to the plan for decreasing the world population to around 450-500 million -- and starting with the US first.
Another one gives out three hypotheses:
Weather Modification
Humans have had the ability to physically affect the weather since learning how to seed clouds in 1946, or possibly 1880. The popular conception of weather manipulation is limited to cloud seeding, but the possibility that the extents of our abilities may have progressed in the meantime is definitely plausible. The fact that the military is very interested in weather control is no secret and many propose that the Chemtrail Phenomena is a part of this. If true, what is the goal of the weather modification and what negative effects could it have on the environment? NASA is currently conducting several programs that are studying the effects of contrails on weather and the effects do not appear to be beneficial.
Population Control
The use of chemical and biological agents by a government against it's own people is, unfortunately, a historical fact. Even unintentional accidents can occur. But, some people suggest that Chemtrails could actually be part of a program to reduce the population and many feel Chemtrails have caused them to become ill and perhaps they are right. If the Chemtrails contain biological agents then people already weakened by other factors may have even died as a result of the additional strain on their systems, but could such a diabolical purpose be the ultimate goal? History has taught that even the most unconscionable schemes can be made into reality by men filled with fear and hate, and with such weapons in the hands of government we must remain vigilant until answers are forthcoming.
Inoculation Program
Chemical and biological weapons have been used for centuries but have recently entered the world stage as a primary threat. Biological agents have the ability to spread and multiply in casualties. These bioweapons are easy to produce and difficult, but possible, to defend against. The recent actions of the military to require anthrax vaccines for all service personnel show that this matter is of high importance. Some propose that the government may be quietly releasing bioagents to vaccinate citizens via the air. This could account for reported illnesses since a vaccine sometimes makes a person sick. Municipal water supplies might not be universal enough and could be easily sampled and tested, but everyone breathes the air. And the federal government rules the air.
Is there any verifiable evidence that there is an ongoing effort to spread chemical or biological agents in the sky for any reason (good or bad) which produce these chemtrails?
