I'd argue the idea of doing something is a strong one. If people become engaged, if they start thinking about the environment on a daily basis then that is already progress in itself. If that means starting with a kettle sure that's probably not an improvement in itself but I'd say the thought counts. People who take/propose such small steps might later start thinking about other means to improve their footprint on the planet that have a bigger impact. They might start to identify themselves as people who care about the environment. They might start spreading the idea to other people. And one day maybe they will say hey I ditched an electric kettle and made a compromise and what did you do, what are the big corps doing? So I hope you engaged the teacher in a positive tone and proposed how we can all have an even bigger impact.
