Where and how to start with responsible shopping?

One of the first steps towards a more sustainable way of life was when I decided to make a more conscious, thoughtful and responsible purchases. Previously, when I was buying in conventional shops I have never wondered where the products come from, in what conditions they were produced and whether they are good for my health at all. And after completing purchases, more and more waste was collected in the waste bin at my home. Every purchase has its consequences! And when I started to realize this, I became increasingly aware of the choice about consumption of goods.
