Please help with the environment! 8th grade project!!!!?

[*Live*Laugh*Love*]

I am in 8th grade, and I am doing this project where you have to pick 3 major problems/things that you can fix in the environment. For example, Shopping Bags, Food, Transportation. Instead of those simple, non-unique ones, I would like to brighten it up with more unique and creative problems. Please help! Even if you can only think of 1 big ideas, please put it down! I want to have a very creative project! Thanks SO much!

Overfishing kills marine life.
The current threat of over population is a global crisis.


Both of these effect the environment.

How about electricity?
Just think about how much energy teenagers waste with their cell-phones, computers, ipods. xbox's, etc..
