Do you believe a microwave involves more pillaging than a gas oven?

Let's say a modern oven isn't available. Just a word burning one. Operating one is an all day amount of work (there's little that's romantic about it). They're dangerous, filthy, and the smoke damages your lungs. If people switched to wood ovens the rest of the world's forests would be pillaged (stripped) of all wood. A wood burning stove has a lot of iron in it, that requires an enormous amount of energy to smelt.

BTW, you should know that gas appliances are a major source of indoor air pollution. Microwaves aren't.

Also, I usually get 10 years out of a microwave. Not bad for an appliance. If you want to save the environment, they sell them in thrift stores for $10-20.
