Why not?

It's just another planet right?

Not as if planet earth is the only unique thing in the universe. Every point in time is unique. Everyone we meet is unique. Every interaction we have with others is unique. Yet we don't cherish them.

So, why this? From what you've been doing so far, saving the planet isn't consistent with your actions.

... so why not?

It's just a human life, right?

How's a human life worth any more than another animal's life? How do you even judge the worth of a life? People don't judge the lives of everyone equally; it's worth more if they can relate to it and empathise with it, and worth less if they can't. In fact, most people would be more affected by the death of their pet than a fellow countryman whom they can't relate to.

You trust such judgements on the worth of life? Then why preach about the sanctity of life? It isn't consistent with your actions.



Conclusion: unbounded insistence on consistency would get us nowhere, even on the most obvious things.

Common sense is common sense even if they are wrong, because everyone else think that everyone else don't know it is wrong except themselves, and they wouldn't admit it because it's obviously true.
