Vinted is a Lithuanian company, just checked it out and it appears to be only available in Europe and the US yet. Their site says it has a growing userbase of now 37 million users (1), so I hope it will spread to other places such as Asia, Australia and Africa in due time.
It’s quite horrific to read those numbers in your article, such as that approximately 20% of all industrial water pollution comes from the production of garments. That being said, it also makes it a relatively easy thing to tackle, in my opinion, as all this pollution and water usage has merely one cause: the production of clothing. If there will be a global consciousness on this, industry responsibility and pollution laws will improve, tackling this issue may have a major effect on the world!
