[BNW] How do I decrease tile yields for a civ?

[Grey Ackerman]

I want to make jungle, forest, and grassland tiles to produce -1 food for this civ only, and make it so it can't be sold. How would I go about doing this?

 

[Grey Ackerman]

Never mind. Figured it out.

Edit: Not really. Check next post.

Post the solution. Then others with the same question can benefit from your figuring out

Here's my idea, but can't add it for my civ as it would be a 3rd unique.
Does anyone know how to get around the 3rd unique problem? It would be greatly appreciated.
