We’ve seen numerous endeavors undertaken by individuals, organizations and government bodies alike, each attempting to bring our world into a more sustainable state of being. But even with all these new initiatives, can we really trust that society is moving at a speed effectual enough to place us ahead of the perils of climate change?

While this necklace may look like it’s best suited for the likes of Darth Vader, we’d certainly wager it’s a better bet than slow asphyxiation via toxic fumes. Check out the video ahead!
