On train home and I see cows in a field chomping, and the grass is very short, but how come they don’t eat all the grass and ruin the field?
What made me think this is locusts or whatever they’re called which destroy crops and leave nothing behind

The part of grass that does all the growing is below the ground level. The grazing animals don’t pull it up by the roots – they snip off the leaves just like us mowing the lawn. So the grass can just keep growing in perpetuity.
This is the same reason why grass can start to grow again almost immediately after a serious land fire. The leaves are burned, but the “living” part of the plant was safe underground.
