Floating between California and Japan is the Great Pacific Garbage Patch—a massive swirl of plastic debris trapped by ocean currents. It's not a solid island, but a soup of waste: fishing nets, bottles, and microplastics, much of it hidden below the surface.

Held together by the North Pacific Gyre, this patch has grown to twice the size of Texas, making it a hazard for marine life who mistake plastic for food.

But there’s hope. Cleanup projects like The Ocean Cleanup and efforts to reduce single-use plastics are making a dent. The patch may be massive, but it’s not beyond reach—every reusable bag, better policy, and smarter cleanup helps.
