PLEASE HELP ASAP I WILL MARK BRAINLIEST.

Explanation:

if you put a lot of cows on one pasture they will end up eating all the grass and then when they run out of grass and they will start to eat all of the greenery and that's how your grass land will end up as a desert. the ways to prevent it would be to put a certain amount of cows  on a  a piece property like if you had a 100 acres you can only have 5 acers a cow you could have about 20 or 30 head of cows or you could have your land separated into different pastures  and move your cows from each pasture when you grass starts getting low .another thing you could do is putting hay out so the could eat on hay and not eat as much grass. and if all the land is used up then it w would have directly disturbed everyone because people need the grass to to feed there livestock and if the land is destroyed then they cant feed there animals then the cows will die from starvation then they cant harvest them and then there wouldn't be meat in the grocery store.

i hope this helps
