Civilization VS Early Man

While I was studying the "Wall of Thoughts" I realized that the world had changed a lot from the past till now. It had become more comfortable and better for us to live in. For example, food. In the past they had to hunt animals for food, eat plants and insects that aren't harmful. But now, we have shopping malls and Cold Storage to get food from. Another example, education. Early man had to teach each other or learn from experiencing. Now, people have tutors, schools, parents and jobs to learn from everyday. As we well aware of, the basic items for human being to live such as ingredients of food, water and numbers of natural resources are remained the same since early man's times. Most importantly, our global warming is getting worse from the polutions that are happening right now.
