last week i was inundated with "take care of the earth" messages. my church had a discussion about global warming; i saw food, inc. in the theater; and i finally watched who killed the electric car on video.
there's a lot that can be said about these topics, theological and not, about what christians should do/think. but i think everyone (myself included) is making it more complicated than it needs to be.
christians are not supposed to be selfish. sometimes they are, but i think they all know that they shouldn't be, and most of them are trying not to be. if there was a small amount of food on the table, you would take it all and leave the other people with nothing, or less than what you took -- so why would you use up all the oil and not leave any for our children's children? why would you put fertilizer in the ground that ruins the soil so that you can have an easier time farming but the next farmer has to content with dried-out, poisoned soil?
just because you don't see the victim of your selfishness face to face, doesn't mean it's not selfish. christians should try to take good care of the earth -- it's part of being unselfish.
