so i need to make a comic strip (in french, but dont mind that). it needs to be about how we pollute the environment and all that crap and its gotta have an environmental moral behind it. you guys got any plot ideas?

Since it's a comic, does it have to be funny?
It's rather serious but this is a big issue and you could show how some corporations are endangering peoples and animals lives by not taking corporate social responsibility. Basically, they don't want to take responsibility of the environmental damages and unforeseen side effects which are called externalities. I seriously hope that you're old enough to understand that. If not, then sorry.

teachers tend to like animal stuff. Maybe you could show somebody cleaning up the waters for fish, a smog control ad for cars, or address a bigger problem about the ozone, and the aerosols which are making it dissapear!

This assignment is probaby already over. Considering it's been 2 weeks since you told us about it. But I say, go with animals and try to be witty. Use the facts as well.
