Here are some key points from the following linked article:
Al Gore backlash: Why environmentalists are celebrating rising CO2 levelsLearn more: http://www.naturalnews.com/040588_carbon_dioxide_environmentalists_Al_Gore.html#ixzz2VG8CxPBt
#3 - The current level of CO2 in Earth's atmosphere is 400ppm. By comparison, Oxygen exists in the atmosphere at 210,000ppm. When you exhale, your own breath contains 40,000ppm of CO2, and if you know anything about emergency first aid, then you know that breathing this 40,000ppm of CO2 into another person's body (mouth-to-mouth resuscitation) is a lifesaving action. It's not uncommon for CO2 to reach levels of 3000ppm in homes, schools and offices. OSHA allows workers to work in environments with up to 5000ppm of CO2. (Because, again, oxygen is present at 210,000ppm, vastly out-weighing the CO2.)
So all this talk of carbon dioxide threatening the entire planet at just 400ppm -- less than one-half of 1/1000th of the air -- is pure nonsense. Total quack science fearmongering.
In fact, most of what we've all been told about CO2 over the pat few years is a complete lie. It's time to stop believing these lies and wake up to reality. Most importantly, stop defending the CO2 / global warming hoax. Yes, CO2 is rising, but it's mostly from non-human activity, and rising levels actually support forests and plants everywhere.
How did I "wake up" to this information? It's simple: I used to be a believer in the CO2 hoax until I really began to study plant physiology and aquaponics production. Only then did I discover that CO2 is a vital nutrient for plant growth and that levels of CO2 in the atmosphere were radically deficient for optimal reforestation and plant biology. My awakening to this in no way means I endorse coal or oil industries, both of which are dirty polluters of the planet. But I am no longer allowing myself to be conned by the likes of Al Gore who has successfully convinced far too many people that their own breath is a global pollutant that needs to be regulated and taxed.
The CO2 scam is nothing more than a global tax moneymaking scheme being pushed by people who hope to get rich off our collective guilt for a problem that's entirely fabricated and fictional.
