Apart from preventing skin diseases, how is the ozone layer significant to man?

All life is adversely affected by ionizing radiation which is the kind filtered by the ozone. Some have evolved melanin and other ways to prevent burning but they wouldn't be evolved for the higher levels. The scare that suggested the ozone layer would be adversely affected by humans was hyped out of proportion. It certainly has had no effect on warming. If it was destroyed, which is impossible since it is continuously formed by the sun, the amount of extra heat would be the least of your problems. You would likely get a m extinction event that would wipe out the vast majority of species.

Where can I find brain teasers / puzzles that come with the charts that help you solve them?

A store on line and has a catalog of brain teasers with all of the solutions. More brain teasers than you can handle. And they're fun. My wife burns the solutions though. I like it that way.

Hillary's NAFTA position?

That is something the Clinton's did back in the 90's. It's been a nightmare since. Yes you are right, it is a huge "job stealer" but they don't care.

I want 3 chickens and i have a few questions???

3 chickens is not much....they dont lay every single day. Of course you can mix breeds. My parents had like 80 chickens and they were all different kinds...its only the males that like to fight which causes problems if you have a whole bunch (I would say 1 male to every 20 hens) but I doubt your getting males since you want eggs. That space is fine...as long as they can all move around without bumping each other. They do like to take dirt baths though so make sure you have a little area of dirt they can lay in.

Brock Lesnar vs Randy "the natural"?

All i want to know is how in the hell did brock lesnar earn himself a tittle shot against randy. Is it that fighters no longer have to have a good fight record to even be considered to fight for the belt!. Just look at Randy's accomplishments and not just that but the amount of fights and dedication,sacrifice that he has given to the sport. I just think its flat out ridiculous that lesnar would have the right to step into the ring with somebody of Randy's stature. I know its all money driven but its just pathetic that lesnar has not proven nor has fought nearly half as many fights as the natural! People don't see that, there are tons of other great fighters who are 12-0 or 9-0 and aren't even close to a tittle match and here's lesnar who is a joke,who's lost half of his fights(4) i'm tired of this crap because fighters like diego sanchez who have proven to be contenders always have one more fight to prove, is the UFC going to wait until they are 46-1 to give them a tittle shot!

Why does he only talk to me at school?

I know a guy from school since 5th grade. He's in my homeroom and we talk at school a lot. It's the end of the school year so we went back to homeroom for 2 hours at the end of the day. We sat together and looked at my yearbook as the others watched the movie. We were laughing and stuff and having a good time. He was definetly flirting with me and I sorta like him now. He said he would date anybody if he likes their personality and he even told me he liked mine. I recently made my facebook account again but when I try to talk to him he wont reply to anything I say. THing is he's really popular so he is busy I guess but everytime he's on I might say "hey" or "how was ur day" or something. But EVERYTIME he wont reply. He seems interested at school but wants nothing to do with me when on facebook. What's with this guy?
