No, I respectfully do not agree 
. Obesity is increased by food in this case, because food is on the left side, meaning being a cause for this. The point is: green means throughout the game ‘increasing’. It could also be red, hence decreasing. Why is food price going up (+37%) increasing obesity? I would say: the arrow should be red, meaning it should decrease obesity. Higher prices = people buy less food.
@cliffski Would you please explain us (or at least me) how to read / to interpret / to translate the visual data of that particular screen into words, since this is the main purpose / mechanic in this game.
Thank you very much!
