Does anyone realize that the above statement is a big lie?
A few minutes with Google finds annual CO2 release numbers:
ALL volcanic activity: 200 million tons.
Burning fossil fuels: 26.8 billion tons (2003)

Which produces more CO2, volcanic or human activity?

Global estimates of the annual present-day CO2 output of the Earth’s degassing subaerial and submarine volcanoes range from 0.13 to 0.44 billion metric tons (gigatons) per year [Gerlach, 1991; Allard, 1992; Varekamp et al., 1992; Sano and Williams, 1996; Marty and Tolstikhin, 1998]; the preferred global estimates of the authors of these studies range from 0.15 to 0.26 gigaton per year.
