Adaption checks.

The last ice age, also known as the Pleistocene, was a time of extreme weather conditions. The average temperature was around 12 degrees Celsius colder than today, and much of the Earth was ice-covered. Despite these harsh conditions, humans survived and even thrived during this period. One reason for this is their ability to adapt. They created tools and clothing to withstand the cold and learned to hunt and gather food in icy conditions. For example, they used spears for hunting woolly mammoths and other large animals and created warm clothing from animal hides. They also built shelters from bones, rocks, and ice to protect themselves from the elements.

While humans were able to survive the last ice age, the next one could prove to be much more challenging. The world's population has grown significantly since the last ice age, and many modern technologies rely on electricity and fossil fuels. In an ice age, these resources would be scarce, making it difficult to maintain our current way of life. However, advancements in technology and infrastructure may help us adapt to extreme conditions. For example, we could develop sustainable energy sources that can be used in cold environments. We could also build more resilient infrastructure to withstand extreme weather conditions, such as stronger buildings and roads.’
