The nature of which continent has suffered little from human economic activity? why?

Of all the continents of our planet, Antarctica is the most untouched by human economic activity.
All this is primarily due to its late development and discovery, as well as the harsh climate, due to which there is practically no permanent population on it, and as a result of this, some kind of active economic activity.
Despite the fact that lately there has been active scientific activity and many countries are developing mineral deposits, the nature of Antarctica has practically not changed.
