I agree with you. I wouldn't be able to make a cellphone from scratch in a million years, but I have researched where they come from, and have settled on only using secondhand units, so that I am not directly complicit to everything which goes into making one.

I've developed a similar stance to most products, and have largely abandoned spending money, exactly because factory farming is not that much different from making a cheap T-shirt, if not worse, in terms of cruelty and environmental damage.
