I want to do a science project like i am going to show two different ecosystem and predict and show which one is more polluted and what happens during global warming????

What my hypothesis going to be then???
Also....
What Future Refrences do I need To Get Before starting this project????

Since it is your project and you have selected what you would like to do, what is it you plan to prove/predict? Which 2 ecosystems have you selected?

Answers to those questions will help you determine the future references you will need.
