Free: Contests & Raffles.
Is this college level English class? Being it is English and not a research paper you will be graded more on the writing then quality of sources. If you want a valid argument then you should start researching pear reviewed papers from the science journals. Your library should have all the resources you need. Ask for help. Journal of Wildlife management is where I would start. Also check USFW reports and papers available on the web. You will find that you will need to replace "strongly regulated and controlled" with managed. There is a lot of information out there that supports management. Look into the WDFW action on the wedge pack. This was supported by science. Don't bias yourself. Always look at it from the other side. Check out a book on critical reasoning and use the rules to argue.
