The New York Times hits the nail right on the head:

Recycling may be the most wasteful activity in modern America: a waste of time and money, a waste of human and natural resources...

We're a wicked throwaway society. Plastic packaging and fast-food containers may seem wasteful, but they actually save resources and reduce trash. The typical household in Mexico City buys fewer packaged goods than an American household, but it produces one-third more garbage, chiefly because Mexicans buy fresh foods in bulk and throw away large portions that are unused, spoiled or stale. Those apples in Dittersdorf's slide, protected by plastic wrap and foam, are less likely to spoil. The lightweight plastic packaging requires much less energy to manufacture and transport than traditional alternatives like cardboard or paper. Food companies have switched to plastic packaging because they make money by using resources efficiently. A typical McDonald's discards less than two ounces of garbage for each customer served -- less than what's generated by a typical meal at home.
