I think that most people do want this ultimately but sadly to do these things that really matter such as switching to electric cars, using renewable energy at home, buying locally sourced produce etc is not incentivised and considerably way too costly for most people to be able to commit to doing the right thing even when they want to.
However there is also a lack of information and practical advice available to educate people about other things that they can do that won't leave them out of pocket.
