Research Paper

I found out something very interesting about myself today in class that I had not realized before.  When we were told to pick 3 topics that really get us going and what we would like to write 10 pages about, I found out that my entire list was about being against killing.  The three things I choose were abolishing the death penalty, having no kill animal shelters, and stopping poaching.  I am extremely motivated to help animals in any way I can.  I am so against animal cruelty, I just need to find a way to truly make a difference in stopping animal cruelty.  My major is nursing but I want to have the ability to be licensed to join an police group against animal cruelty also.  I would be so happy having two jobs that involving saving animals and people.  I am just really disgusted with killing and torturing anyone or anything.  I found that I am definitely going to write about this in my research paper.  I am not sure which topic motivated me the most or which one I can accurately and effectively get my point across.  I think I have decided I want to talk about animals in my research paper but I have many topic I could do like: hunting, poaching, rainforest deforestation, endangered species, euthanizing animals in humane societies, and animal cruelty as a whole.  I feel so strong about them all.  Any advice on which one I should write about?  I am excited for this paper because I am motivated to have research to back up my points and convince others to make a difference also.
