What is the biggest problem in society?

I think that the biggest problem in society today is wastefulness. I feel that people, especially in this country, have problems conserving resources and exploiting too much of everything. You can even tell that we're wasteful just by looking at the massive size of the landfills we take up. A lot of that is food and materials that can be reused. It's called a recycle bin! I don't mean that you should recycle food, because that would be weird... I'm just saying that if people ate all the food on their plate (African children, anyone?) and recycled, then we would have a lot less trash. AND STUPID PEOPLE SHOULD STOP CUTTING DOWN TREES WITHOUT PLANTING NEW ONES!!! GEEEEEEZZZZZZZ THAT MAKES ME MAD -____-
