It is NOT a coincidence that Al Gore’s global warming propaganda masterpiece, Earth in the Balance, was found among Ted Kaczynski’s belongings in his ramshackle hovel in rural Montana. For those who may be historically challenged or suffering from memory loss, Ted Kaczynski was the violent serial killer who became known as “The Unabomber”.
The Unabomber’s lengthy “Manifesto” called for the “destruction of the worldwide industrial system.” Both Kaczynski and Al Gore drew inspiration for their rants from numerous sources, including eco-terrorist Dave Foreman, founder of EarthFirst! and The REWILDING Institute.
The strategy for using violence and threats to accomplish green objectives was first implemented with great effect in the 1970’s by a cadre of anarchists and environmental extremists. “Monkey Wrenching” was the term coined by radical environmentalists who engaged in spiking trees, destroying machinery, and blowing up infrastructure. Unlike the more sheepish Gore, Kaczynski publicly claimed that the best way to implement the brave new “green” world order was by knocking off “Scientists and engineers, especially in critical fields like computers and genetics.” 
A comparison of quotes from various well known individuals rationalizing the use of violence and societal destruction to accomplish radical environmental goals provides startling revelations:
“Only with the Industrial Revolution did the effect of human society on nature become really devastating. To relieve the pressure on nature it is not necessary to create a special kind of social system, it is only necessary to get rid of industrial society.” – Unabomber Manifesto (Sec. 184)
“We are trying to subvert the system. We would like to see the system collapse. When I say the system, I mean the modern industrial system as we know it….The deep ecology movement, or the EarthFirst! movement, would like to see human beings live much more like the way they did 15,000 years ago, as opposed to what we see now.” – John Davis, Managing Editor of EarthFirst! Journal
“We already have too much economic growth in the United States. Economic growth in rich countries like ours is the disease, not the cure.” – Paul Ehrlich, Stanford University biologist; Special Advisor to Vice-President Al Gore.
“Isn’t the only hope for the planet that the industrialized civilizations collapse? Isn’t it our responsibility to bring that about?” – Maurice Strong, Chairman 1992 Rio Conference and founder of the UN Environment Programme (a.k.a. “Agenda 21”).
“A massive campaign must be launched to de-develop the United States. De-development means bringing our economic system into line with the realities of ecology and the world resource situation.” – Paul Ehrlich, Professor of Population Studies, Stanford University, Special Adviser to Vice-President Al Gore.
“Adopting a central organizing principle – one agreed to voluntarily – means embarking on an all-out effort to use every policy and program, every law and institution, every treaty and alliance, every tactic and strategy, every plan and course of action – to use, in short, every means to halt the destruction of the environment . . . Minor shifts in policy, moderate improvement in laws and regulations, rhetoric offered in lieu of genuine change—these are all forms of appeasement, designed to satisfy the public’s desire to believe that sacrifice, struggle and a wrenching transformation of society will not be necessary.“ – Al Gore- Earth in the Balance p. 274
“It is necessary to develop and propagate an ideology that opposes technology and the industrial society… And such an ideology will help to assure that, if and when industrial society breaks down, its remnants will be smashed beyond repair, so that the system cannot be reconstituted. The factories should be destroyed, technical books burned, etc.” The Unabomber Manifesto [Sec. 166]
“We must identify our enemies and drive them into oblivion.” – Bruce Babbitt, Secretary of Interior- 1991- speaking about conservatives, independent rural Americans, ranchers and farmers, land developers and other assorted “anti-green’ capitalists.
“The system does not and cannot exist to satisfy human needs. Instead, it is human behavior that has to be modified to fit the needs of the system.” – Unabomber’s Manifesto [Sec. 119]
“The big threat to the planet is people: there are too many, doing too well economically and burning too much oil.” – Sir James Lovelock, BBC Interview
“I honor EarthFirst! for having the guts to do the things they do.” [Blow up timber mills, spike trees, destroy private property, threaten people, etc.] – Brock Adams, VP, Audubon Society, quoted in the Los Angeles Times.
“I personally believe there’s going to be a crash. I don’t know when, or how, it will take place, whether it will be a pandemic, a massive economic crash, a clash of centralized state governments, a massive famine, or whatever, but I do know industrial civilization cannot go on.” – Dave Foreman, EcoFuture interview with Derrick Jensen
One particularly evil source of radical environmentalism deserves some added recognition. Perhaps the most infamous serial killer of all time, Charles Manson, claimed that it was his love for the Air, Trees, Water, and Animals (ATWA) that motivated him and his followers to embark on their murderous rampage.  Manson’s radical green organization, ATWA , posits the same inhumanity towards his fellow man as does the modern green agenda. Manson’s tactics were a only a bit more brutal, as he believed that slitting open a mother’s womb and stabbing an unborn child to death was an environmentally friendly act not much different than modern abortion procedures, which many people besides Manson believe to be a necessary and beneficial procedure for limiting human population growth.
Another follower of the radical environmental death cult is James Lee, the man who became known as the “Discovery Channel Killer”. In justifying his murderous rampage against employees working at the T.V. network, Lee said:
“The world needs TV shows that develop solutions to the problems that humans are causing, not stupefy the people into destroying the world. Not encouraging them to breed more environmentally harmful humans.” – James Lee – the “Discovery Channel Killer”
But not to be outdone by his murderous brethern, Dave Foreman claims:
“We must make this an insecure and inhospitable place for capitalists and their projects. We must reclaim the roads and plowed land, halt dam construction, tear down existing dams, free shackled rivers and return to wilderness millions of acres of presently settled land.” – Dave Foreman
“My three main goals would be to reduce human population to about 100 million worldwide, destroy the industrial infrastructure and see wilderness, with it’s full complement of species, returning throughout the world.” – Dave Foreman
Other notable “greens” such as Ted Turner, Bill Gates, and Steven Rockefeller, echo the same anti-human murderous agenda as the most radical environmentalists. As if fulfilling the dreams and aspirations of any number of deranged psychopaths who have gone before them, these “concerned citizens” are spending billions of dollars to promote and institute global eugenics programs, including forced sterilizations and anti-fertility chemical vaccinations that have been proven to induce still births and miscarriages.
It is a very thin line, if indeed one exists at all, between killing innocent humans via the distribution of vaccines which are intended to cause infertility but may also induce abortions or miscarriages, and the admittedly cruder methods employed by James Lee, Ted Kaczynski, or Charles Manson.
As far as the radical green agenda is concerned, the mass murder of human beings is not only environmentally justifiable, it is inevitable. While some wolves in the green movement appear to be wearing sheep’s clothing, underneath their disguises they all exhibit the same ravenous appetite for death and destruction.
“[Charles] Manson’s advocacy for the religion of death, and his call for violence in the name of global warming and overpopulation, would be dismissed as the inane rantings of an evil psychopath if it were not shared by people holding significant positions of power in government, academia and science today.” Paul Joseph Watson
