What do you think swarming locusts affect planted crops?

they say yum yum as they eat planets and make humans starve

Explanation:

but they still eat them

Large swarms of locusts can completely strip the foliage and stems of plants such as forbs and grasses ... They often eat dry plant matter on the ground and will forage for weak or dead grasshoppers when plant food is scarce. As nymphs have a large appetite, they cause more damage than adults.
