I sometimes wonder when the next ice age will come. Does anyone else ever think about stuff like this? I wonder what will be the fate of humans when it comes, and more interestingly what the next reigning life form will be if humans don't survive (remember the ill-fated dinosaurs?). I'm fascinated by the mammals that did survive the last ice age! If some of you think that humans and dinosaurs existed together and dinosaurs perished while humans survived, feel free to speculate what you think will happen to humans during the next ice age.
