And how do you think the device you're using to read this was built and transported to you?

You've just made my point.

A kilo of meat uses many times its weight in water, grain and fuel to produce. The same goes for many manufactured goods, my device included.

But domestic electricity usage of a computer? Yeah, that's immaterial and makes the point poorly.

The point is not that you should stop using your laptop, rather that you should not have bought it in the first place to avoid encouraging the practices you dislike. If you keep buying and using your laptop, that means you're ok with everything that went into the process of building and transporting it to you, as you're helping financing the very process you denounce. It's like buying and eating meat of protected species and saying "hey, I didn't kill the poor thing".
