Providing feedback, or aggregating behaviours, will help people visualise the impact that they have on the environment.

With the given information, people can learn to set their own goals to reduce the amount of times they take food away without bringing their own containers.

Using feedback and setting goals for people will help them to see the impact of their current actions, and can thus, guide them towards improving themselves. This is especially useful as most people are unable to see the immediacy of the effects of their actions. Quantifying a person’s impact thus helps to make the association between their habits and their actions clear. This is crucial in helping a person take their first steps towards committing to making a change.
