An environmental group wants to stop a huge project because of a fish. They plan to sue Mazda Toyota, and the city of Huntsville, over a big factory that’s being built. The group, Center for Biological Diversity says the project will pollute a spring where pygmy sunfish live. Mazda Toyota says it has tried to work with the group to protect the fish and stopped construction earlier this month — but now a suit is planned. And construction underway again.
