Can cities tax or ban commodities from certain areas (i.e.-Rain Forest)?

Question

Purpose is wildlife preservation.

Answer 1

I don't believe it would happen at that level of government.  Municipal governments are not responsible for international trade; that would be a Federal responsibility.

Answer 2
