How can we break down these barriers?
Various insights from behaviour science have shown that gradual, incremental change to achieve goals work. It is said that individuals make 35.000 decisions a day, with 226 of them about food alone. With this in mind, being able to consciously make small changes in decisions every day - even if starting with only one out of the 226 - is already a good enough start to change food habits and hopefully make it feel rewarding in the long run.
Have you seen a business or government changing their behaviour based on the demands and actions of individuals?
Yes. I think this is certainly the case for the plastic issue.
