Good illustration. In Asia, the tundra is either still there if you are far enough north or has become the greatest grassland in the world. Extensive Siberian forests though still dominates much of the land. Different environments dominate different niches for reasons humans haven’t reall effected until you get into China where deserts have replaced grasslands for reasons of climate. The other little parts have enough farming to feed billions without really dominating nature except in the river valleys. Even in tropical Southeast Asia, the river valleys have been modified to produce primarily rice. The American Midwest is thoroughly changes to accommodate agriculture but is we were to disappear, grasslands and woods would reappear.
I’m not saying we cannot do a great deal of damage (the Amazon) and unwisely use our environment (areas of desertification in Africa and elsewhere) but even there we can mitigate it.
