In order to rail against he over-fertilisation of lawns, the excessive use of pesticides, Ted Steinberg makes this mindboggling statement:
While some of the company\’s claims for the environmental benefits of grass are reasonable – lawns do indeed cool the surrounding air, at least relative to, say, asphalt – others are just plain silly. Exhibit A: Scotts says 2,500 square feet of lawn produces enough oxygen for a family of four. Hello? The world is faced with many ecological problems, but a shortage of oxygen is just not one of them.
Can you spot the error?
Excellent, for of course the shortage of free oxygen (ie, O2 moelcules in the atmosphere) is in fact the largest ecological problem we face. You know, the IPCC, Kyoto, climate change, boiling Gaia and Aieeeeee! we\’re all gonna die!
The entire problem is based around the fact that much too much of that lovely O2 is in fact in another molecule, CO2, and floating around the globe, leading to Greenland melting, Bangladesh sinking below the waves and the last humans will end up barbequeing Flipper in the coming end times. All of this is predicated upon the fact that we\’re putting more CO2 into the atmosphere than the current ability of extant vegetation to fix it, by taking in the CO2 as food and releasing O2 as the by product. This is why people advocate growing forests and the like, as they so often do.
It\’s true that a lawn doesn\’t add all that much to this process, but every little helps, right?
