But, im confused

I just got done talking to Ms.Savido on how i wanna do something with animals, but i think animal abuse to common of a topic to do. So i searched online on animal projects, and when i came across something about animal extinction. I thought of using that but what would i make my topic about, when i thought about polar bears and how global warming is getting worse and the animals in the cold climates are getting affected by it and going into extinction. So i thought what if my question was this: What do you suppose will happen to polar bears if global warming worsens?
