humans can have things on their shoes and leave it on the ground to make soil
Soil can be made unproductive by salinification (which is often the result of prolonged irrigation) or by depletion of needed mineral content (after prolonged farming, without fertilization).
Because the soils are generally nutrient poor
Physical Geography is the natural side of geography. Weather, rocks, soils, etc. Human is cities, roads, buildings, urbanization, etc. We humans affect physical geography by living. We build roads and buildings. Our cities cause a heat island which is kind of a bubble of heat in urban areas. This is hotter than the surrounding cities. It can influence rain and climate downwind of the heat island. We dump things chancing the soils. There are other ways, but this is a general start on some of the ways that human geography affects physical geography.

Humans depend entirely on science and research. Science revolves around every move of humans. So, we can't guess in how many ways it is helpful.
Three ways with which humans interact with the environment include dependency for livelihood, to modify it and adapt to conditions.
