Helps?
The claim that haze and smog diffuse sunlight, allowing a greater dispersion of sunlight to leaves may be true, if accurate.
What I can't believe is that this is seen as helping.
Most environmental issues have positives and negatives, but helping implies an overall improving of the situation; helping a man with a flat tire out by buying him a Coke doesn't do shit.
it's called global dimming, there's a good horizon or panorama episode about it. don't watch the nova version though all the info has been dumbed down.
