What keeps the oxygen "pollution" from plants, from getting too high in the atmosphere? If oxygen level was much higher, forest fires would grow uncontrollably and consume entire forests. Perhaps by allowing some of the oxygen to naturally burn off. If not via natural wild forest fires left to grow naturally and burn themselves out naturally, then perhaps by small controlled burns in power plants and in cars? Such smaller "controlled burns" sounds to me to be more human-friendly. I would rather there not be the emissions, if we could have better technology such as electric and free-energy cars, but strangely there is NWO elitist and liar mad-scientist resistance to that idea.
Anyway, I seriously doubt that nature worries about why some people supposedly need such big SUVs.
Way too much enviro-wacko fear-mongering. And is is undeniable that plants need CO2.
