How the field works
It's spring — plant corn by dragging across the soil. Through summer it grows tall;
in fall it ripens golden and the farmer harvests whatever's left.
But mice and voles wander in to eat your corn, and they breed fast. Your job is balance:
raise barn owls (they hunt all night), keep a few barn cats (they prowl by day),
and a scarecrow spooks mice nearby.
Poison works fast — but an owl or cat that eats a poisoned mouse gets sick and dies too.
Real farms learned this the hard way: a single barn owl family eats ~3,000 rodents a year,
which is why owl boxes beat poison.
Watch the graph: more corn → more mice → more owls → fewer mice → … the whole web breathes.
