Finish an Era with at least 1000 Food being used by Villages
Ocean Animals and forest Giant plants are your best friends in this development. The ideal situation you’re looking at is to cover the world in forest and simply proceed to clutter its tiles with the aforementioned resources in excess. Focus on placing resources and the villages will come.

If you’re having issues then don’t forget about replacing resources once you gain access to improved abilities. Placing level 2 plants with the Forest Giant can lead to Pear Trees that generate 70 Food instead of 40, a rather dramatic increase when applied worldwide…
