Boosters buildings affect the income your dragons earn when ON THE SAME ISLAND. Each such building gives a bonus to one element and hinders another one.

Organize your habitats and the dragons that live in them to make sure that as many dragon as possible aren't on the same island as a booster that works against one of it's element.
