What do mixing crops and livestock allow farmers to do?

There are always different things that farmers need to do to make sure that their crops and livestock will be amazing. A lot of them rely on the weather in order to ensure that their crops and their livestock will do well.

Some farmers know that they are going to lose a lot of money if the weather does not cooperate. If all goes well, they will not have enough in order to live a comfortable year but if by the next year, things do not go as planned, it will require them to make more effort in order to make ends meet.
