It's bad enough that smog, fuel emissions and other industrial pollutants may contribute to asthma. Some years ago, I read a study about how non-indigenous plants caused health problems by introducing pollen allergens in communities where people were planting lawns and trees instead of xeriscaping.

Now, some of those same communities are trying to control the use of water by encouraging residents and business owners to xeriscape. Perhaps, in doing so, there may be a positive effect on public health, as well as on the economy.
