In our current state of living, we MAKE and USE things that cannot be repurposed or reused, after which we DISPOSE them in a way that is harmful to our environment. This is why we have ever-growing landfills in Nairobi. This is the Linear Economy.
The solution is to find a way to ensure that we draw our resources from materials that are already in circulation. This means replacing the Linear Economy model with the Circular Economy Model.
