In the movie: A single mother’s business of a Locust farm isn’t doing so well. She discovers by accident that blood makes them thrive, and does her best to hide her secrets. In real life: In the movie, Locusts are sold as protein; i.e., as food for both human and non-human animals. In an ideal world, one we hope to live in someday, we wouldn’t need to breed insects and other animals because we shall then only be relying on plants for food. Like Slugs, Locusts are a threat only to plants, which could be solved by making a concoction of garlic and water to be sprayed on leaves. Kind of similar to what you do to ward off aswangs, right?
