Science type program on TV a week or so ago was about CO2 and global warming. It suggests that due to the present amount of CO2 in the atmosphere, grasslands are prolific and forests aren't growing as well. They have very good data to support this. They think this is happening because the CO2 level is LOWER than it should be and LOWER than it was in the past. CO2 is, of course, plant food.
Go figure eh?
Next they'll be telling us that salt on our food isn't bad for us! (Oh, they already did.) Or that margerine isn't really better for us than butter. (Oops, they already did.) Well, at least no scientist will ever tell us that beer is good for us. (You say they already have? And wine too!!!)
I give up!
