#9 farmers and humans will need to move around more and tear down more natural land to find suitable soil or else there will be famine all over

#10 since farmers have to till massive amounts of tops soil in order to be able to use the land it cause erosion from the wind rain etc. causing land to fail cause mudslides etc. then famine start setting in cause there would be now more suitable land for farming cause farmers would move around and use up all the land.


i hope these are right if one is wrong then put in comments
