What Is The Legal Way To Deal With Nuisance Wildlife?

I’ve seen a number of questions where people have squirrels or bats in their attics, or deer eating their flowers, or geese polluting their lakes, or coyotes threatening their pets. The answers on this subject run the gamut. Some people say to just shoot it, to trap it and relocate it, to poison it, etc. And some people say you need permits to kill or trap/relocate wild animals that are damaging your property or threatening your safety. What’s the legal way to deal with nuisance wildlife?

What Graduate Degree Should I Get If I Want To Work In Wildlife Conservation?

I am currently finishing up my B.A. in Public Policy. Unfortunately, I’m not overly strong in the math department. This would make it difficult for me to do an M.S. in a hard science area.
Does anyone have any ideas of what I could do? Working with wildlife is my dream, but I’m not sure what academic route I should take.
