Humans still have evolutionary pressures caused by drugs, war and
ecological changes. Pollution is one of those pressures, medicines are
another (thalidomide resulted in an unsuccessful mutation, for example).

Evolutionary pressures exist. However, there is no way (evolutionarily speaking) of judging what is the successful strain because advances in medicine don't let them just die off.

See changes in average heights, for example.

This is not an evolutionary change. This is just due to better nutrition now (as compared to whatever historical period you care to name) in the growing years.
