Clothes is a nice and easy one to begin with choosing an alternative for because it's a much more simplistic product with a more easily traced supply chain. Phones, computers and cars are something we'll likely struggle with for a long time.

For anything else, the public will likely need to demand change as I doubt a superior or equal alternative will emerge. With that said, products like the FairPhone are very interesting, though I haven't used one.

Food is something that'll largely hinge on your geographic area and availability of produce that makes sense.
