I need your help. The people in my town are interested in catching birds recently. These birds are caught to be sold. We are afraid of the future of the birds. I am going to suggest the mayor that we should make some laws to teach the catchers a lesson. Do you think it is a good plan? I hope you can give us some more ideas as a good lawyer.
