We often focus on consumption, during these discussions, but there also needs to be a focus on the need for an ever expanding economy, growing companies, increasing shareholder value, growing market share... for the most part, businesses are not filling a need but creating a product that is then marketed to consumers.

There is a growing industry in products that are made from natural fibres, processed so they perform like plastics, we are being sold a lie, these 'like plastic' materials will still end up in landfill, our compost will have 'like plastic' particles in it which will disturb the balance of the soil and still have an impact.
