How might life be different if the ice ages had not occured?

Hope this helps. History is the answer of the future it's high time that people realise the threat of Global Warming and the Next Ice Age that would be associated with it. How can we deal with our brains from now on, simply because it will be useful in the human life; if not us, may be for he next generation to come. Most of the foreseen problems are solved with a good study of facts related to similar issues in the past. Thus, the lessons we leant in the past about Charles Darwin's survival of the fittest, come back suffer extreme cold, extreme heat, malnutrition, and above all, a fastly reducing human race. I would say people should start getting used to eating what they get, instead of choosing what they like. Hope it helped!
