PIG topic

So I'm almost positive on my work of art. But the topic is the tricky part. I'm thinking about the pollution in the oceans or the world in general. Either way I would like to make a 3-D model for my project. Either with clay or some other type of ... stuff I guess. I feel like the amount of trash on our planet is disgusting. Every where I go I see tons of it on the side of the highways, in lakes and rivers and we all hear about it on the TV. Is it really hard to recycle or throw things in a trash bin? Not just out the window because your lazy. My car is a mess I will admit but I clean it out every so often and recycle what I can. I'd rather it be in my car then in a deers stomach or around a skunks neck. I guess I'm done ranting for now. But seriously, Pick Up After Yourself!
