Between the hybrids, the reusable canvas shopping bags and cloth diapers, everybody's doing their little bit to save the world. Entire industries have sprang up to cater to us socially-responsible types who want to leave behind a better world for the robots to inherit once they take over.

But, most of the time, making you feel better is about all it does. For instance...

#5. Buying Organically Grown Food

Why People Do It:

Seems like a no-brainer. Organic food eliminates the use of chemical fertilizers, hormones and pesticides. Getting rid of all those nasty chemicals means healthier foods and less contamination to the planet.

And anything that's organic or natural has to be better for you, right? It's like you're eating the opposite of Twinkies here.

Why They Shouldn't:

So what's the problem with eating healthier food and saving the Earth? Nothing, except that the food may not be any healthier. And that's even if you can afford the (much) higher prices. Oh, and the impact on the planet may actually be worse.

The funny thing about those chemical fertilizers and pesticides is that they were invented for a reason, and that's to increase food production. Turns out organic farming is pretty damn inefficient. Holding hands and thinking peaceful thoughts does **** all against pests that want to eat your crops and weeds that want to choke them out. The current acre of farmland produces 200 percent more wheat than it did 70 years ago. The same goes for meat and poultry. The chemicals did that for us.

Take them away, and suddenly you're getting less food per acre of land. According to some guy who won a Nobel Prize, we could feed 4 billion people if we went all organic. This sounds great except maybe to the 2.5 billion people who would be left without anything to eat...
