Plastic bags are one of the main contributors when it comes to waste issues, apparently due to the fact that they are not biodegradable and that they would most likely be harmful should some careless people resort to burning them.
But just like other plastic-based materials, plastic bags can be reused too. In fact, maybe you can even use them as prime materials like this Hammock Chair.
With about 500 plastic bags, two spring link carabiners and rope, you can do this Hamock Chair all by yourself. The result is a comforting chair which can reportedly hold up to 220 pounds of weight.
The plastic bags are apparently braided into such, making them alternative materials to the common braids made of nylon or cloth to offer the restful piece which you can probably have up by your backyard.
