It's high time my mind was opened to encompass other fundamental fields into my vision of sustainability besides just the environmental one. I think it'd be most appropriate for me now to talk about circular economies and my new steer away from fast fashion.

The design of new products would then incorporate these recycled materials, with a lesser need for raw materials. To illustrate:
