Alas, even if you are not one of those "get your hands in the dirt" kind of people, you might still be affected by the increased CO2 Another effect is that ragweed is creating more pollen, so airborne allergens are getting worse as well. (just in case you thought the reports that claim every year is the "worst yet" for allergies was hyperbole) A link to an article about scientists who are studying the effects of CO2 on plant and specifically weed growth:
At this point, I am not even sure what has been the worst part of all of this, the actual physical reaction (disgusting rash and mad itchiness), or that the physical reaction has caused me to not sleep well, and is so distracting, that concentrating for any period of time is difficult, and reading to retain content impossible, or lets face it, that the rash is intensely ugly and disfiguring. (ahh, vanity!)
Coincidentally, DH and I planted more than 65 trees this spring-what are you doing to help combat the rise in CO2 levels?
