Great Migrations: Feast or Famine

Every migration is an epic journey, driven in large part by hunger. Every day, trillions of creatures are moving in search of greener pastures. From microscopic plankton to rare desert elephants; from predatory bald eagles to luminous jellyfish; from ravenous Great White Sharks to lightning quick peregrine falcons; our planet is on the move. Countless creatures on timeless journeys, moving in numbers, surviving as one.
