Before we go into more detail about these highly controversial issues, we need to clarify what we mean by these terms, because you always have to look at what they are for today's "science," politics, the environment, and, of course, the human Health and safety mean.

A Weapons of Mass Destruction is a chemical, nuclear, radiological or biological weapon capable of killing or severely damaging large numbers of people, not to mention the massive damage to manmade structures and the biosphere. 

Pesticides are the only toxic substances that are intentionally spread in our environment (and regularly) to kill living things. "Pesticide" is the generic term for substances that kill weeds (herbicides), insects (insecticides), fungi (fungicides) and rodents (rodenticides) or other agricultural pests (pests).

Chemtrails are part of a continuing mass distribution of biological waste products and pesticides in the air. At first they look like normal contrails in the sky, but they are easy to distinguish. Because they dissolve much slower, because they are not formed by a normal water-based condensation. Chemtrails are therefore much denser than contrails and often spread x or lattice in the sky. 
Vaccines are experimental injections of morbid drugs designed to cause an unnatural over-stimulating immune response in humans to mitigate the effects of later infections by "wild" pathogens. The efficacy of vaccines has never been conclusively proven either in theory or in practice.

In fact, "dead" or "weakened" microbes and viruses in the vaccinated person come to life again, provoking the most contagious disease that immunization should protect, and ensuring their spread. Even if the vaccinated victim does not get sick immediately from the inactive virus, well-known carcinogens and genetically modified organisms are now included in all vaccines, including flu shots, and can cause serious health damage in the short and long term.

Some of these agents or "adjuvants" are mercury (termed thiomersal), monosodium glutamate (MNG), formaldehyde (baling fluid), and aluminum (which can be shown to cause Alzheimer's disease). Not a single vaccine has ever proven to be safe for the human body despite paid studies published by the manufacturers. Today's vaccines have been proven to help spread more than 25 infectious diseases, including polio and measles. 

Biological and chemical weapons are used for population control in America and developing countries

No other country in the world has a greater interest in limiting population growth than the US, especially in eugenics - ethnic profiling and the hindered proliferation of the colored population - while the globalists and super-rich assert themselves, the minorities and underprivileged to help with "food" and "medications".

In fact, US law allows testing of chemical and biological agents in the civilian population. Although there is no such authorization, no democratic voting procedure protects the wellbeing of humans, animals and the environment. And many even declared philanthropists like Bill Gates or George Soros to support depopulation by funding, promoting and distributing genetically modified foods (carcinogenic, pesticide-laden foods) and vaccinating unsuspecting citizens with toxic substances.

Under the guise of charity, "unwanted" sections of the population are systematically eradicated by food and medicines that are supposed to help them. Vaccines such as those against DTaP and HPV make female teens infertile. The Kenya Catholic Doctors Association accuses UNICEF and WHO of sterilizing millions of girls at the start of their childbearing years under the guise of the "anti-tetanus" vaccine program (funded by the Kenyan government). Scientific studies by independent laboratories have shown that at least half a dozen of the tested tetanus vaccines from different regions of Kenya confirm the worst fears: they have tested positive for the hCG antigen contained in contraceptive vaccines.

Zika Virus Dizziness: Actually, Naled Exposure Causes The Birth Defects That Bring Mass Media Back to Zika 

Right now, in a 25-square-kilometer area in Miami-Dade County, one approved by the US Environmental Protection Agency (EPA) and the Health Department CDC War against humans instead - under the pretext of Zika virus fraud. The highly toxic insecticide "Naled" contains dibromo, which has been proven to cause birth defects in humans even at low concentrations. Ultimately, this is where a weapon of mass destruction is used in the name of insect control - and the US population has been so stupefied by fluoridated water and pharmaceuticals that it actually believes the government cares about it and wants to help.
