How does a person adapt to unfavorable environmental conditions?

In our time, a person has almost completely lost the ability to adapt to unfavorable environmental conditions. We have learned to use animals, plants and any natural substances for our purposes. Since we can dress warmer, the person does not have a coat. In people in the desert, there is no change in the shape of the eyes, since we can use glasses. This applies to almost all irritants that caused changes in the organisms of our ancient ancestors. Now, we use the means at hand.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
