Each year human activity currently adds over 30 BILLION TONS of CO2 to the atmosphere.
Thats a staggering amount of anything to be loading into the skies - 30 billion tons! And as the graph suggests the amount is increasing rapidly. I cannot understand how anyone could assert that 30 billion tons of CO2 couldn't possibly affect anything, let alone the climate.
What we are struggling to realise in the west is that the Planet is not so vast, or human activity so insignificant that we couldnt destroy it.
Just something to think about.
